Colt / Umarex M4 Carbine .22 Tactical Rimfire AR-15
Colt and Umarex have teamed up to produce the Colt M4 .22 Tactical Rimfire. The is probably the only real “Colt M4″ you will ever be allowed to own!
I am not 100% sure they are in fact AR-15s. UMAREX USA uses well known brand-names such as Beretta, Ruger and Walther to sell their airguns. This could easily be a AR-15 patterned rifle much like the .22 GSG MP5 or GSG AK.
There will be four different models.
Colt M4 Carbine
* 16″ Barrel
* M4 collapsible style stock
* A4 flat top upper recoever
* detachable carry handle
* A2 flash hider
* A2 pistol grip
* 30 round magazine
* Weight: 5.95 lbs
Colt M4 OPS (includes the following extras):
* Rear BUIS (Backup iron sight)
* Free floated aluminum picatinny rail handguard
Colt M16 (includes the following extras):
* 20″ barrel
Colt M16 SPR (includes the following extras):
* 20″ barrel
* Free floated aluminum picatinny rail handguard
* Flip up read and front sights
Fake suppressors will also be available as seen in the above photo.
It will be officially announced at SHOT Show 2009.
Hat Tip: OnPointFirearms
Good marketing when they said “COLT M4″. It’s an outright lie. I wounder what the action for the .22lr will be?
I have a Ceiner .22lr conversion kit on one of my AR15 build. My cousin bought four Spike .22lr upper, three of which sold to our gun club members. Both use the Max Atchisson .22lr design.
I was thinking about adding a folding stock to one of my strip lower because the Atchission doesn’t use a gas system. It is a recoil base action so there is no need for a buffer tube.
There are a number of .22lr upper and conversion kit for the AR15. The demand for .22lr AR15 outstrip the supplies chain. Very long waiting list.
BTW don’t buy the Ceiner kit directly from the manufacture. You’re not going to get it for sometime.
Here is the link to the Spike .22lr upper.

Steve,
the M4 isn’t all that great, I have carried them for years and would rather have the M1A SOCOM 16, or a H&K 416.

It would be a breath of fresh air to get a cheaper .22lr upper than what Spike’s charges. Hell forget about getting a ceiner kit from ceiner, he’s an asshole and a bad businessman.
Get the CZ v-22 if you want a cheap .22lr upper. They are around $250.
Ceiner isn’t the best person to deal with. That’s why you don’t buy it directly from him. Get it from an online store.
There are a number of .22lr ar15 manufactures. Spike is desired because they make their upper compact and offer SBR version of it.
nice looking rifle. if the price isnt to high. i would definitly be interested in finding out more about it! i wonder how long before it is going to be in stores?
jdunn, where are all those cz v22’s you speak of? from what i’ve found they haven’t been made/imported in a while. other than the upper on a sun devil lower that is on GB (and has been forever) i haven’t seen a single one for sale. i’d definitely buy one if i could find one.
as for the colt/umarex m4, i’ll wait till after it, the s&w m&p 15-22, and the sig 522 come out. let the jones’s go out and test them all. then buy the one which is working the best. let’s face it, these likely won’t be the shooters that the dedicated uppers (with the right twist) are, but all 3 look like a lot of fun.
it looks cool, i saw it at a g.a.t. guns factory shoot and the guy said it was a semi auto gun
Is this gun going to be non-restricted in Canada…anyone know?
Yes the Non-Restricted permits have been approved for the new Clot .22 M4
prices are not confirmed yet, they say anywhere from $600- $1100… so that is a big range at the moment, more details will come closer to the release date.
Stay Tuned !
Umarex has posted a website for the Colt .22 Rimfires: colt22rimfire.com.
Interesting … it seems this will be a better shooter than the Sig 522, since the Sig 522’s twist rate is 1 in 7″ (inappropriate for .22lr), while these M4’s all use 1 in 13.75″.
Scratch that last comment. The site I was looking at for Sig had the twist rate wrong. Sig 522 is 1 in 16″. Sorry.
These are dedicated 22’s. The uppers will not fit on an AR lower. I played with them in KY and they feel the same as the real deal when it comes to the size and weight. The S&W is a polymer frame gun, even the quadrail is polymer. Conversions for AR uppers usually don’t work great due to the bore being larger than a 22lr needs. Umarex USA is a couple of blocks away from my shop, and they have done their research. As a matter of fact Walther actually makes the gun.
I just bought this gun and it is excellent…the quality unlike what others have said..not flimsy whatsoever….it’s made tough but the metal is light. Performance is wonderful…really accurate and reliable.
I just got the tactical carbine myself. The rifle is very solid and shoots quite accurately. I mounted a Leupold 1×14 Prismatic sight, and it is very accurate. The pistol grip is non-standard, even though it looks like it might be. I pulled off the wobbly butt stock and replaced it with a MagPul CTR. Strangely, the standard M4 carbine was being offered at the same price as the tactical M4 carbine. I expected to pay at least $100 more for the quad rails w/covers, but they were both $595, making my purchase a no-brainer. It shot Winchester value-pack bulk ammo just fine, but didn’t care too much for Remington value-pack bulk ammo. I will most likely run CCI ammo through it from now on.
I have just ordered the standard m4 online for $599. The next day I noticed that the ops version had gone on sale for cheaper! I believe it was only $589! At the time I placed my order it was about $650. Anyway. Does any one know what the threading is on the barrel of the standard version? I assume that it is threaded at 1/2×28 to accept the muzzle break that it comes with (or is it just for looks?)
Not sure what the threading is, but the muzzle brake is removable. A few oddities I noticed:
1) The very basic pistol grip is proprietary, with two holes (one for a pass-thru pin from the trigger group, the other — toward the rear — to mount the Allen screw). Standard AR grip options will NOT work as their hole(s) does not line up at all with where the screw mount would need to be. I did quite a bit of modification and drilling to get a Hogue grip mounted (which was worth the effort). Shame they couldn’t have made that part STANDARD!
2) The recoil buffer tube, although mil-spec diameter, does NOT thread into the receiver the way a standard AR does. Instead, the castle nut is mostly for looks, because that tube mount to the receiver via an Allen screw that can only be accessed by removing the end-cap at the end of the tube. Bottom line, you can’t change tubes out, but you CAN replace the 5-position butt-stock with a mil-spec after-market version. I first tried the CAA version which went on easy, but was WAY too wobbly when fully extended. I then went to the Mag-Pul CTR which has the lock-down lever, which fit much better, and took the wobble out.
3) Very impressed with the accuracy. The free-floated barrel of the “tactical” version (quad rails) certainly lends to this.
4) Trigger pull is rather heavy, but consistent with little play or over-travel. Didn’t take long to get used to it.
5) I wish there was a way to lock the bolt open (other than inserting an empty mag then pulling back the charging handle). The lever that would normally do this on an AR, is also on this rifle, but it is cosmetic and non-functional. Hmmm…
All in all, I am pleased with this rifle, and proud to finally own at least SOME type of Colt AR. I hope you find these observations useful.
Ed, did you get the email I sent you?
I understand this is going to be California legal withthe 10 round clip. Talking with Colt the lower id dedicated to a 22lr and cannot be changed out to a .556 so there should not be any issues in California. As you know., AR-15’s (all) are illegal unless you have a bullet button on the lower assembly. I just want a tactical rifle. This is a rimfire and shouldn’t have any issues due to the “Ban” list…. Any coments on this ???
Anybody else have trouble with the magazine falling out the bottom when you pull the trigger? I bought one of these Colt/Umarex AR looking .22 M4 Ops rimfire rifles at a gun show last week, paid $599. The first time I went to fire it, the mag shot out the bottom and hit the floor. I tried it again with the same result. After checking it closer, the magazine was not locking in, and the cartridge was actually being struck on the side by the firing pin (yikes). I called Umarex and they ae sending me another mag release button to see if that will fix the problem. I’m curious if anyone else had this problem, or am I the lucky one?
Anyone having extraction issues. One of mine, carbine, does not grab the spent reliably, the rifle never misses an extraction.
Has anyone figured out how to disassemble the receiver?
I could fix the extractor if I could figure out how to do a takedown.
Tim
My Mags all seem to fit snug with a semi forcefull snap into the reciever. Im afraid you got a bad one..
CLEANING: \
How is the besy way to clean the bolt and breach?? It doesnt want to come apart any futher after the upper is dissconnected. The Manual says to always start from the breach???
I’m using a .22 bore snake , it works,, and wondering if im missing something else or better?
In responce to steve’s comment. “The first time I went to fire it, the mag shot out the bottom and hit the floor. “
Like any AR when you insert the mag, give it a firm tap from the bottom to ensure the mag is seated. This one seems to need a little firmer tap than normal. I got a few minor complaints. The rear retaining pen is way to tight, have to use dowl and hammer to get it out, and I cant figure out how to take it down to clean the chamber. Anyone out there got a take down file for it? We had a blast with the little rifle at the river yesterday. I have three AR’s. I shoot an AR in 308 by DPMS, girlfriend shoots the 223 by rock river, and I got this colt 22 for my ten yr old daughter. I’m happy with my puchase. Now if I could just take it apart to clean it. Any Help?
I purchased an ops version in June 2009. Fantastic plinker. Put a $75 sight mark laser/holo sight and it is great. Hates Remington ammo but Winchester and Federal bulk ammo do well. The bolt can be locked open by reaching up in the mag well with a finger, but the bolt release is just for show. 1″ patterns are easy at 40 yrds with halo sight.3″ with laser. Careful if you break it down…the fake bolt release and “bumper” (bolt stop) will fall out. Breaking down further than just removing the upper is pretty complex. The barrel is a light weight tube that sits inside the heavy external barrel. It is held in place by the flash threads on the flash supressor or compensator. The good thing is that replacement barrels are cheap and you should keep one handy if you blow a lot of 30 rnd clips. The action seems cheap and loose, but is accurate and reliable and it holds up well. We have run 8500 rounds thru it so far without problem, but it likes to be field cleaned and oiled in the after two boxes (1100 rounds). We keep a snake, Qtips, bore cleaner and oil in the tactical case ($29 at Gander Mountain). Buy a couple of spare mags (35.00 ea) and go have a ball. I wanted an AR-15 but couldn’t justify the ammo cost. This thing is more fun and costs pennies a round. Shooting at night with the laser is better than sex (almost). I have 4 boys ages 10 to 16 and we all love this toy. Highly recomended for the $550 price the get on the internet. Have fun!
Picked mine up for $500 NIB off of GB. Been a great little plinker. By no means should this rifle be compared to an AR other than appearance. The fun that can be had adding options from the AR world are unlimited. My AR22 M4 has worked great right out of the box. I picked up a couple of extra mags and have been having a blast with it. I have left owning the real AR’s to my friends and love annoying them with the look a likes. My Safir T14 has been well accepted and I believe that in time they will come to like the colt M4, once they get their noses bent back in place.
Follow up on my June 24th question about anyone having their mag fall out of the bottom. Colt (Umarax) sent me a new mag release assembly at no charge. I installed it and still could not get the mag to grab. I called Umarex, they sent me a call tag to send my Colt M4 Opts .22LR in for warranty repair. Waiting to see what they find. I saw one at a show last weekend and tried it out….the mag snapped in ok (nothing like an AR feels, but it snapped in). I’ll report how my rifle is repaired.
A video was just posted on field stripping it:
http://www.colt22rimfire.com/index.php?page=videos
Is the trigger similar to real AR-15s? I have a RUGER 10/22 with the Arch Angel conversion and I really like it. But it only looks like an AR (kind of) it still doesn’t feel like one when shooting and I want to get the most out of my trigger time.
So my question: is the travel, creep, weight, break and reset feel like a GI trigger?
Howdy Gerod — In my opinion the trigger feels similar to a standard issue AR trigger. It seemed a little heavy at first, but has lightened up a bit after extensive use and additional lubrication. I too, have a 10/22 w/Arch Angel conversion, and I agree that its feel is way different than an AR, or this Colt 22.
Steve:
I also had problems with the magazine catch. The mag stays in and the rifle shoots fine, but even the slightest pull on the mag and it comes right out. Tried the other 2 mags I have and same thing. Had my gunsmith look at it said to get a new mag catch. Called UMAREX this morning they said they have had a few of these issues and are sending me a new mag catch. Hopefully this fixes the problem unlike the new one you got Steve and I dont have to resort to sending the rifle in and wasting time my time.
Other than the mag catch issue the rifle has been awesome. First few hundred rounds I had about 5 FTF from light firing pin strikes and one stove pipe, but the past 500 or so rounds have had no issues. So far it shoots anything I put in it from CCI mini mags, Federal Game shok, and federal bulk. Put a holo-red dot and its accurate all day long.
Steve: keep us updated as far as turn around time with the warranty repair. this will be a good test of UMAREX’s warranty and customer service capabilities. Hope they are prepared for dealing with gun owners and not their regular customers who are probably 10 year old kids that purchase their airsoft guns.
Thanks Ed! I think I have to get one. I have gotten really excited about 10/22 conversions. I think have enough people here to start a support group for those of us who have ripped our hair out because of the cinere kit.
“Hi my name is Gerod”
“Hi Gerod”
“I have been cinere kit free for 3 months now and I just don’t want to put myself out there just to get hurt again.” ;,(
just kidding. I put in my order today with scottsdale gun club and will report shortly.
BTW scottsdale gun club said that they got about 30 in a week ago and had to send them all back. They were broken in half, things missing, etc. and they had to give refunds to another dozen or so customers who bought them.
Update on my mag falling out while plinking: I sent my Colt M4 Opts version .22LR in to be checked out (after they sent me a new mag catch and it didn’t solve the problem). After only about a week turn around, I received my Colt back today and the mag grabs nicely. It looks like they did some gunsmithing as opposed to replacing parts. Either way, the mag holds nicely. Going to the range tomorrow to finally fire my new toy. Umarex was quick and kind in handling my situation. My hat is off to them! I didn’t know what to expect, as I have never had a problem with a new pistol or long gun EVER.
Jon-I think Umarex is prepared. They are ready to handle warranty situations, at least in my case. Thanks Umarex!
“Nothing is better than the service behind it”. I’m impressed with the service I received from Umarex.
I just purchased the colt m4 22lr, and so far I really like it. It seems to be the most accurate 22 cal. rife I have ever shot. I matched it with a bushnell 1×32 red dot scope that really looks go on the gun and at 25 steps will hit the same hole every shot. Next step will be to shot at longer ranges. Only shot around 200 shots so far but really like it so far.
Just got the NEW Colt .22LR …made the mistake of putting Remington ammo through….lotsa problems….switched to Winchestor…as fast as you can pull the trigger it cycles! Loving it….
How do the rail covers come off….have the M4 OPS version…
Thanks!
Howdy Doc,
Push down hard on the steel spring clip and slide forward at the same time, and the rail covers will come off. They are clones of the Knights Armament design, and are every bit as nice. I put a standard ladder rail cover on my top rails, after installing my optic.
Remington bulk didn’t work well for me either, or anyone else that I had heard from. Just like you, absolutely no problems on Winchester bulk, or Winchester up-scale, or any CCI versions that I have tried.
Enjoy!
Update:
Just received the new mag release from Umarex, installed it, and shazam the mags stay in! Thanks Umarex for resolving my issue in a timely, professional manner.
While installing the new mag catch I also turned in the bolt speed adjuster all the way on the recommendation of the video that is now posted on the Umarex web sight about field stripping.
I have had very few misfires and most of them came in the first few hundred rounds, but hopefully they will be all but non existent now.
Has anyone else found the front sight post to be on short side?
I have to run mine all the way up on both my carbine and rifle.
Tried regular AR post but threads are different.
Wonder if there will be optional front posts available???
Tim
Hey Tim,
I just shot mine today for the first time and found the same situation. Front sight post does seem too short as well for me. Ran it up as far as I dare. Also shooting extreme to left, had to run rear sight almost to full right to bring group in line. Not real happy with the iron sights, but had a blast with it anyway. I think a scope of some kind may be the way to go here. Iron sights, shooting 36 grain Federal (Blue Box) ammo, sub MOA at 25 yards, 1 1/2 MOA at 50 yards and just over 4 at 100 yards. No feed or ejection problems with ammo, but expect a flyer every so often. I wonder how CCI would group? No its not my AR HBAR, but its still fun and cheap to shoot.
I also have HBAR and a couple of NM AR’s but with ammo and reloading prices I have been shooting the 2 colt rimfires most.
The carbine that had eject problems went back to Umarex last week for tweaking. The rifle now has red dots and scope to play with. At 100 yards using Remington match it but the majority in a 2 -3 inch group with a fair amount in x ring. Really suprised me on the 100 yard range. Just bought last 5000 round match ammo case from CMP yesterday so that should last a week or 2!
Tim
I had to run the sights up real high also. They are about an 1/8 to 1/4 inch too short. The retaining spring for the sight also pops out. I will call Umerex tomorrow!
Having the SAME problems with my front sight! I ordered a Holo optic…I guess that will fix the problem as long as I have battery life! Any news from Umerex in regards to the short sight? Let us know….Thanks!
Called Umarex today. The Armorer there said that they knew that some of the sights were too short. Is sending me a taller one today. He also said to adjust the tension on the spring nine turns and that should help with most ammo.
I now matched my m4 with a nikon 3×9x40 scope and it really is a good match for the gun. I shoot cci mini mag in it and it never miss fires, not like the remington that the gun would not even load. I would recomend this gun for anybody. The gun isnt the problem that most people are having its the ammo. All guns like different ammo, this gun is not an exception.
Called umarex on the 7/21 recieved the taller post on 7/24. Great turn around time. No cost
New front post sight! Dead on shots now!
I am ordering an M4 OPS. I was wondering what the fire control group looks like. Is it comparable to an AR-15/M-16?
MACHINEGUNBOB
The fire control group is unique not interchangeable.
Tim
I received my carbine back today everything works much better now, mag stays in well, new taller front sight, new recoil buffer and spring, now shots all my match ammo, and extractor now works 100%.
Now I just need to send rifle back and they will be a fine pair!
Tim
Hey All!
Has anyone heard that Smith and Wesson is making a .22? I looked for it online it looks pretty nice.
Yes, it’s called the M&P15-22, and you can read more about it from this same blog, @ http://www.thefirearmblog.com/blog/2009/01/20/sw-mp15-22-a-22-lr-tactical-rifle/
Unlike the Colt, it is polymer, but claims to share many components with the AR platform (probably things like the pistol grip, where the Colt falls short). It’s supposed to be shipping right around now, at an MSRP of $499, but only in the tactical carbine configuration (unlike the Colt). It will ony have a 25-rd mag capacity.
Hi Ed. I read the TFB page on it. Some irritating dweeb arguing that $500 is too cheap…
To me the Colt sounds better. Plus On your previous post you were saying that you could modify a pistol grip to fit it. The ONLY thing that would make choose the M&P would be if the trigger was interchangeable or at least very similar to the USGI trigger. It looks like it isn’t though. 7lbs!
Does anyone know the trigger weight of the COLT?
i had the same problem with my colt m4 .22 . My magazine would not seat correctly. My gunsmith told me to send it in but i decided to keep tinkering with it because i knew it was going to be something stupid. Sure enough i found if i slightly bent the “lower receiver pin” or the part thats attached to the spring on the opposite side of the mag realease the mag seated perfectly.
Bought the M4 Ops model. Very nice construction but had the same problem with elevation as others. UMAREX is sending me the longer front post. The front sight is an “F” type. Was told that this is shorter than the standard front sight. (The whole sight not just the post) Hopefully I will have the same result as others and all will be well. Also have the problem of shooting very left. If the rear sight is centered at 50 yards, it shoots about 12-16 inches left. When corrected have very little left in the rear for a true windage issue. Tests were done in no breez and in a protected berm. No wind at all. I will replace the front post and go from there. BTW UMAREX was very responsive.
Hey Robert,
When I talked to Umarex about my sighting issues, they sent me a new front post and recommended removing the tension pin holding the front sling guide. Under that is a set screw (1.5mm) which may be backed off to allow you to tap (I used a rubber mallet, dead blow) front sight mount/gas tap block in the direction required. I suggest you do these adjustments at your range if allowed, as it may require a couple of tries to get sighted in. It worked for me. Mine’s a M4 Ops also. Added an elevated red dot also for more fun.
Tim – Thanks for the info. on the trigger group. I want to (legally) convert mine to select fire. I guess I’ll have to whittle out a hammer and sear on my Bridgeport. I have an 07 FFL/SOT so there are nor legal restrictions for me to do this. When I figure it out, I’ll make up some blueprints and make them available to other people that want to (legally) convert their gun. The .223 M-16 is getting really expensive to shoot. Plus, I can shoot the .22 LR at the indoor range.
Thanks again, Tim
BOB
Bob, my former boss (also manufacturer/SOT) has been asking me to help him figure out how to do this. LMK if you have some success!
It might be easier to do it on the M&P 15-22 because it uses GI lower parts but we haven’t examined one in any detail. We have been messing with the Colt a bit if we have any success I will let you know.
Gerod
hi i bought one of these colt m4 22 carbines and let me tell u iam far fron impressed the gun was fine the first 90 rounds of 22 ammo i put through it using the federal bulk 22 from wallly world but after that the gun started jamming anf miss feeds and then the saftey fell out i lost it somewhere well i called uramax and they are sending me a call tag all i can say is lets see what there warranty is like so far iam very unhappy wasting 600.00 dollars on a gun that iam beginning to think is junk this the first time i ever got a lemon with all the guns i have bought over the years but like i sais we will see if they fix it and how good is there warranty .
Gerod – If I have any sucess, I will let you know. Are you familiar with the “Lightning Link” for the Ar-15 to M-16 conversion? A modified version just MAY work on thee Uramex. If you want me to email you blueprints for the lightning link, let me know, and I’ll scan them and send them to you. I will need your email adress to do this.
Thanks
MGB
BOB
Gerod – My email adress is: bobanick [ a t ] yahoo [dot] com
Bob,
I sent you an email.
Received my S&W M&P 15-22 today.
Storm was coming up so I only had a chance to try 200 rounds of different ammo.
Observations:
It feed and fired every type of ammo I had. Even the Remington that would not chamber in Colt. Never missed firing or had any feed problems.
The wind was up put it does not appear to be as accurate as colt. Eley Practice seemed to group the best, wind was a factor but I tried for calm air.
Things I liked:
Seems to have same trigger group as AR
Both front and rear sights are removable.
Bolt comes out same a AR for cleaning.
Very light weight, maybe a little too light.
Eats all types of ammo and does not complain.
Well made as far as I could tell.
Things I did not like:
Accuracy, need to put scope on in calm air to verify.
Tim
I got my M4 OPS today. I tried shooting CCI Velocitor ammo thru it. I failed to feed about 75% of the time. VERY dissapointed. I tried some old cheapo Federal ammo in it, and it worked good. It could not have been the difference in velocity, because it failed to feed the first round almost every time. The first round is fed by the spring alone. It can not possibly have anything to do with how hot the ammo is. Maybe I’ll learn to like this gun once I figure out what ammo it likes besides ancient Federal. It shoots to the left, even with the rear site adjusted ALL the way. All over, I was very dissapointed with this gun. I am an 07/SOT N.F.A. Manufacturer. I looked at the fire control components. Tim feels as though this trigger group is similar the AR-15. It does not look at all like an AR-15/M-16 fire control group to me, but then I did not completely rip the trigger group apart, so Tim may be right. He may have torn his down to the casting. I did not. Overall, I am very dissapointed in this gun. Buy a 10/22. It may not look as neat, but they shoot every time you pull the trigger. This gun may work good after they make a few million of them and work the bugs out of it. But for now, I would never recomend one of these. Someone didn’t do their homework before they went into full production. This gun is still in it’s secondary tryout period. And they are having paying customers send them back the bad ones so they can figure out what is wrong with them. That’s exactly what the U.S. auto companies did in the 60’s and 70’s (Chevy Vega). And they are still paying for it with customer confidence that was lost, and never re-gained. Colt is going to severly tarnish their reputation by letting someone stamp their logo on this gun. They should have named it “High Point” or “Raven”.
I am a federally registered N.F.A. gunsmith and that’s all just my opinion, for whatever it’s worth. I may be wrong. My wife tells me I am all the time.
BOB
Bob
I was frustrated at first but now I am a fan! The feed problem is related to bullet diameter ( I believe ). I can run all types of new and old Federal with no problems, same with Wolf Match. I should go out to car and get my notes but a lot of ammo works OK and over all it is at least as accurate as any 10/22 I have built. Also more accurate than the S&W M&P 15-22 I just finished doing more testing with today. The factory told me that Walther used a match reamer for chamber and it is tighter than normal. Some ammo just will not seat all the way in chamber due to oversize lead. You would not notice this as much with a bolt gun but I do notice this with H&R 12 match rifle, some ammo is hard to seat. Umarex offered to open up chamber but I am reluctant to do so, I may let them do my carbine but keep tighter chamber in rifle. I also had them install (they will also ship) a new taller front sight and mag catch, worlds of difference.
Try some Federal ammo, even Dick’s Federal blue box 714 worked well.
Tim O in NC
Bob,
I thought you LOVED it! What happened? Also, I think Tim was talking about the Smith and Wesson M&P not the Colt.
Gerod
Bob,
Also, Try a different rear sight. I sometimes have issues if I buy a cheap CAA carry handle rear sight. I will ship you a good one if you want, though I am sure you can get whatever you want. Also try Tapping the front sight base over a little or possibly a new sight post. Maybe the hole drilled for the front sight post wasn’t drilled straight…
Don’t give up buddy!!! We need ya! Plus who is going to help me look smart in front of my old FFL/SOT boss when I know how to make his go FA?
Gerod
(All NFA rules apply and are always followed in everything relevant that I do. Only grubby dirt shooters even think about breaking them)
The chambering issue I had were with Colt, S&W will digest anything I threw in Mag!
If your mag pulls out easily take the mag release lever off and file the upper surface of catch boss slightly .010-015 will make it latch in and not pull out. Takes 10 minutes in old man mode!
The S&W is very pickey on accuracy as to what works and does not.
Colt is fairly accurate with anything that will chamber, so far it seems Eley Practice and Wolf Match (not extra match) seem to one hole at 25 yards.

Bob…Thanks for the info. Just received the new front post and from the height difference, it should solve my elevation issues. I will try the front set screw and see it I can, gently, reslove the azimuth issue. I will post when I have worked it. Just an asside, my M4 has functioned perfectly with almost any ammo but some old CMP Remington (The lead seems very soft but is the best in my H&R M12). The new Remington Match/Target works fine. The El Cheapo Federal functions just fine. I tried Eley Tenex, Federal GM, all worked with NO malfunctions. Group-wise the Remington and Federal are pretty equal at 50 yds.
Took the M4 OPS .22 to the range today for the first time and WOW…what a great fun gun!!!! Easy to operate, adjust, and maintain. Be sure to adjust for high velocity ammo before your 1st trip to the range as I did. No jams for me with almost a 500 round brick used up!!! Great gun!!!! WOW
I just can’t justify doing work on a brand new gun that is under warranty. If I do anything at all to it, Umarex could void the warranty, right? I am going to send them the gun back, with a letter telling them my problems with the gun. I paid $665 for this gun (delivered, with four mags). That’s a lot of money for a .22 LR that doesen’t work most of the time. And when it does work, I can’t hit anything because of the sights are off farther than their adjustment. I have built belt-fed machine guns, submachineguns and just about everything in-between (legally). I’m not going to do a bunch of work on a brand new gun that is under warranty. Hopefully, they can fix it. If not, I will expect my money back, or a different gun. If it was some $100 gun, then maybe I could say “Oh, well”. But for over six and a half hundred, it should have worked good right out of the box. I bought an American made Walther PPK once. It was a piece of junk, too. I guess they are living on their name, not how good their guns are. From now on, I’ll build my own. If they don’t work, I can only get upset with myself. And I already don’t like me, so it doesen’t matter, right?

Bob , I am sure they will honor their warrenty. WHen I first shot mine , it was rough at first. The tension spring needs to be set before you shoot. The armorer at Umerex said to turn it 9 times. Not 9 380 degree turns, but 9 twist of the wrist. The more I shoot this rifle the better it gets. just needs some break in time.
Johnny – I wonder exactly how many revolutions nine twists of the wrist is supposed to be. It’s like when my Grandma baked a pie. A pinch of this, a dash of that. In today’s high-tech world, telling someone “nine turns of the wrist” is not very specific. This must be the kind of logic that they used when they designed and built these guns. And they turned out just like Grandma’s pies. One was fantastic. The next one would taste like cardboard. Leaving important items to human guesswork is exactly the opposite of Quality Control. A guy named Deming wrote a book about this subject. The Americans ignored it. The Japanese auto companies used it like a Bible. That’s when they started kicking our corperate butts in Quality and customer satisfaction. I loved my Grandma. But I wouldn’t trust her “pinches” and “dashes” logic to build weapons with. This gun reminds me of the pies she made that tasted like cardboard. Take one bite and spit it out. Give the rest to the dog under the table. Grandma taught me a lot. Mostly what NOT to do!

Tried the higher front sight post today. Resolved the elevation problem. Then I pushed my luck. I swapped a handle from my Colt HBAR. Right back to being 2 feet high. Funny thing, using this handle resolved my azmuth problem. Hmmmmmm……. Anyway now I have to see if I can have a handle. I would think the shorter (Standard A2) handle would be the best fit. If you use a hightr Mil_Spec handle for the “F” marked FSB it would aggravate the problem. Oh well I will keep trying.
try 9 180 turns. this is what I did and it shoots great.
Just bought a S&W M&P15-22 this week for $495, and took it out today and ran a couple hundred rounds through it. Then I fired my Colt AR-22 from the same bench rest, and got similar groupings. I thought the Colt was really neat until I got the S&W. Fit, finish, and overall quality look quite good, ever though the upper and lower are predominantly polycarbonate. Similarities are clearly greater to a standard AR-15 than what the Colt offers. Pistol grips, butt stocks (without tube), picatinny rail accessories, and trigger assembly interchange with standard mil-spec AR options. That part is really nice, and better than the Colt’s limited interchangeablity of just picatinny rail accessories and the butt-stock (without tube).
I saw some links where folks think the Colt is more accurate, but I do not find that to be the case. They are fairly equivalent in my testing at 25 yards. The S&W, however, seems to take-down easier for cleaning, which is a plus.
BTW, I also saw the S&W at Academy for $449. Of course, I stumbled across that after I already bought mine. Oh well….
Umarex called me today and gave me an RMA number to send the gun back with. I wish I would have bought a S&W from the start. I can’t sell the Colt (I am an FFL holder) as a new gun. And even if I did sel lit as a used gun (and took a beating on the money), I would be selling someone a gun that I know they won’t be happy with. And I really can’t justify keeping the Umarex and buying a S&W, spending a total of $1200 for two .22 LR guns. All I can do at this point is to send the Umarex back to them, and hope for the best. I guess praying would be about the only productive thing I could do, but I doubt if God really cares about wether my .22 works, or not.

I find it interesting how someone with little knowledge of a subject now thinks he is an expert. I have been in the quality business for 30+ years. Do you truly believe quality is a measure of how many turns it takes to adjust something? Would you be more satisfied if someone stated to rotate a wrench 360 degrees 9 times from the 12 o’clock position? Don’t you believe quality is related to customer satisfaction? Maybe you should read some of the other comments on this blog. It sounds like there are some very satisfied customers out there. Have you ever seen any auto company tell you their defect rate, Japanese, German, American or any others when you attempt to sell you a car? They relate quality to customer satisfaction! JD Powers! Etc. It sounds like Johnny was satisfied with his answer. CUSTOMER SATISFIED! You should really read Mr. Deming’s work. It involves a whole lot more than you think you know about. You build/modify firearms one at a time probably taking several days or weeks. Manufacturers build them on a production line where you have variations in each process and each component. The idea is to limit the effects of the variation so that the end product still meets the customer’s requirements. I can see that they have had a few issues but based on what I have read they have addressed them so that the customer is satisfied. No product has ever hit the market without some problems. That is why in the Quality field we have what is called “Continuous Improvement”. That is how we all get better. By the way I am a M4 Ops owner and I am more than satisfied. I have shot the M4 carbine and the M16 versions of these rifles and they all performed well.
Quality Observer – How could you possibly state that I have little knowledge in the subject of Quality Control? I have worked in the Quality Control Dept. at General Motors for over 24 years. We rate our Quality in defects per 100 cars. I work in the C.M.M. room. Yes, you are right. One measurement of Quality is customer satisfaction. But anyone with mechanical knowledge does not explain how to correct something in terms that can not be nailed down. We measure things in one thousands of a milimeter. I know that this is not needed to explain how many turns you need on a screw, but just stating “nine turns of your wrist” is a little vague, don’t you think? The Lordstown factory where I work produced thousand of Chevy Vega’s. They were at about the same Quality level as a Yugo. Junk. As far as J.D. Power and Associates, they started out as eleven people renting office space and test driving cars that they rented. For some reason (their ritzy sounding name?), the public took what these people said as gospel. So the car companies starting loaning them new cars to drive. Special ones that they had their best mechanics double-check every system on. Then they started letting them keep the new cars after they test drove them (providing they got a favorable test report). Demings work involves a lot more than I think about? How could you possibly know how much I know about Deming? You are making assumptions. Assumptions that I am some backyard gunsmith. Nothing could be farther from the truth. I work in the Quality Control Dept. at G.M. I am the trainer/team leader in the C.M.M. room. I am a customer of a Umarex gun, and at this point, I am not satisfied. Like I said in my previous posting, I sent the gun back to Umarex, and I”ll see what they do to it, and how it works when I get it back. Maybe I will be a satisfied customer in the end. I was merely making some observations about the gun I bought, and what other people told me about their experiences with theirs. Assuming that you know how educated I am, or how well I know Deming’s processes is assuming a lot. I may just be a little bit smarter than you think. I just happen to have a different opinion than you. We do not agree. That’s OK. But please do not state that we don’t agree because I lack an education, or the life experiences to judge a product that I have purchased. That just isn’t playing nice. Don’t forget. In this instance I AM the customer. And at this point, I am not satisfied. Hopefully I will be when I get it back. Let’s all play nice and talk about the guns. Not about each other. On this blog, I really think that it’s the gun that counts, not our personalities. Can we agree to disagree, and not cloud the issue with each others thoughs about the other guy? I hope so.
Thanks for the input, and God bless.

Good comments Mr Quality! Love the Colt OPS! Ordered the Gemtech suppressor adapter today to run my AAC Pilot. I’ll let everyone know how it works!
The Gem-Tech adapter works great. I got mine for my AWC can a few weeks ago. It seems like Gem-Tech makes some really fine products. I also have a G-5 supressor from them. Very impressive. I really like the cam lock setup. With the adapters, I could put it on the Umarex, but it would be way too big for it. I hope that when I get my OPS back from Umarex, that I will like mine as much as you like yours.
MGB
Take the wrench that came with the rifle and loosen the flash suppressor two full turns. That loosens the rear pin and you can drive it out. Are you shooting Remington ammo? It doesn’t like Remington. Bolt speed might need adjusted. Check your owner’s manuel.
Mary – I was unsucessfully shooting CCI Velocitor and Stinger. It did like the cheap Federal. It shot the Federal with no problems. Umarex has got it back right now. Hopefully, it will shoot OK when I get it back. It seems as though the diameter of the chamber was tight. I could be wrong, because I did not measure it. I guess that if I take it out with different velocity ammo, then I’ll have to always take the adjustment wrench for the bolt speed with me. I’m sure that after some testing, I’ll know where (how many turns) to have the adjustment screw for the different types of ammo I use. Thanks for the advice about Remington ammo not working well. I won’t bother wasting my time trying it. I usually shoot CCI through all my .22’s. Maybe the Umarex just doesen’t like CCI.
Thanks again for the advice.
God bless

BOB
I want to thank all who have contributed comments here. Great example of the incredible community of knowledge made possible by the internet. After reading through these posts, I made the “educated” decision to buy the Colt, and am taking to the range tomorrow.
MGB,
My apologies to you. There was no malicious intent. I agree it is ok to disagree. I hope and pray that you are satisfied when all is said and done.
God Bless
Machine Gun Bob,Wish I could’ve read your comments before i bought my colt M4. I got mine and couldn’t fire 6 rounds in a row without jamming or primer light strike problems.I have and do own a lot of colts and have never had a problem with them.I tried serveral different type of mmo with same problem.I have sent it back twice now and am in the same boat you are.Can’t resell and get money back. They know me by name there now. I just wanted to take time to thank you for writing and to let you know you are not the only disatisfied customer. I recently purchased a gsg5 and what a difference 1000 rounds without a hickup.
Quality Observer – I’m glad that there are no hard feelings. It’s all about the guns, not you and I, right? It seems like m4noop is having the exact problems I am experiencing. Like you said, hopefully they will fix it up well enough for me to sell it as a used gun. I’ll loose a bunch of money, but at least the guy I sell it to may like it. I am WAY too fussy when it comes to guns. You are right. I build them one at a time, and fuss over every detail. You can not do that on a production line (unless you are going to sell the guns for tens of thousands of dollars apiece). I look at every gun as a weapon. If I do not have 100% confidence in it, I get rid of it. I had a Glock model 27. It worked perfect for hundreds of rounds. One day it “stovepiped” a round. I put it up for sale the next day. I know that this is not acting like a normal person, but I never claimed to be normal. Picky, yes. Normal? No. Guns to me are like a wife. She only has to cheat on me once, and I will never trust her again as long as I live. Thanks for the reply. It’s a small sandbox. We might as well play nice.
m4noop – It distresses me that you have sent the gun back several times, and it still does the same thing. If that happens to me, I will cut it into two or three pieces with a band saw and send it back to them and tell them to use it for a suppository. I’ve done it before. I am not a rich person. But I expect guns to work every time. If a company can not make some little .22 plinker work right, then shame on them. 40-plus years ago (when I was a boy) I bought a .22 Winchester semi-auto. The kind with the tube that holds the rounds under the barrel. I’ve put thousands and thousands of rounds through that gun. It’s gone years in between cleanings. That gun has never jammed once. And when you are 12 years old, you don’t clean, or oil your gun. I never even owned a cleaning rod for the first few years. Every winter I would take it over to my friend, John Konya’s house and use his cleaning rod. I shot it after carrying it around all day in freezing weather while it was snowing. I shot it at a limestone quarry when it was 100 degrees and had super abrasive limestone dust everywhere. It never jammed-up. Never. 40 years later someone can’t make an auto loading .22 to work brand new, at an indoor range at 70 degrees, and no dust/dirt? In 40 years’ time, I figured that guns would improve, not get worse. And you could still probably buy several of those little Winchesters for what I paid for the “colt” umarex. The problems that you are describing are EXACTLY what my gun does. Exactly. It sucks, but maybe if tou try some cheapo Federal ammo, it will work. I haven’t actually measured the bullets with a micrometer, but I’ll bet that the Federal ammo is a few thousands of an inch smaller than the CCI, or the Remington that won’t work. I bought an adapter from Gem-Teck so I could put my AWC supressor on the end of the umarex. Where on earth am I going to find subsonic ammo that this thing will cycle? Probably impossible. We just put a new blade in the big Do-All band saw last week. I hope the colt doesen’t need to get ran through it. Those companies really don’t know what to do when you send them a gun back in pieces. I tell them to remove that serial number from their production book. The paperwork involved for them to do that is probably more than it costs to fix the rifle, or re-issue a new one with the same serial number. I hope I’m luckier that you were. I hope they fix mine. It’s a shame when you buy a brand new gun that says “Colt” on it, and you have to hope and pray that it will work. I’ll bet Sam Colt is turning over in his grave. He knew what a quality gun did. It tosses a bullet out the end of the barrel every time someone pulls the trigger. Modern quality control was not even thought of back then. Like the insurance company says “it ain’t rocket science”.
Machinegunbob
m4noop be sure to adjust your ammo setting inside the gun before your 1st trip to the range. It is pre set to low velocity ammo and the screw needs to be turned inward(below flush)…..try that and report back…..gentleman’s bet your problem is solved!
Derek, Don’t want to get in a online argument here but,I spent a day off and on with Umaex on the phone trying to troubleshoot this problem and trust me when I tell yuo this did not fix my particular problem with the gun. When they sent it back the last time it will shoot CCI maxi mag with some irregularity. This will be one of those guns that I will shoot for fun ocassionaly when it decides to fire,but will never depend upon to save my life. Again not trying to be a colt basher here.When I invest 600 dollars in a gun I expect it might shoot better than my 200.00 ruger 10/22 which I would not hesitate to pick up with any ammo and defend myself or family.
m4noop -Personally, I think you are right. For the price we paid for our two Umarex guns, we could have outfitted eight people with Ruger 10/22’s. I am no fan of Bill Ruger. I feel he did some anti-gun politics when the magazine capacity law was being decided (he only sells guns with 10 round capacity). But he makes reliable guns. Colt used to make good guns years ago. The U.S. Military buys M-16’s from F.N. now. Pistols from Beretta, of F.N. As far as I know, there is presenty no gun that Colt makes for our military. I MAY BE WRONG. I am no military weapons aquisition expert. But Colt sold the U.S. military Colts for years, then they lost their contract. Umarex is only going to make guns’ quality to the specs the their parent company (Colt) demands. If Coly’s guns can’t pass muster with the military, then it’s safe to assume that they are not going to hold Umerax to a higher standard than they hold themselves to. Again, this is merely an observation from an outsider. I do not work at Colt, or Umarex. I work At G.M. Having product/company loyalty is a great thing. Big companies live or die from repeat customers. Selling someone a poorly functioning gun, car, or whatever it is, only makes you a few dollars today. The real money is in making something good enough that they come back to you year after year and continue to hand you money. Colt/Umarex is failing to do this. Maybe not with everyone, but I think they have got their last penny from you and I. I bought this gun primarily so when I take my two Grandkids out to the range, they can shoot a gun like my AR-15. Handing a child a malfunctioning gun may sour their fun. Like going fishing and not catching any fish. Plus, there is a serious safety issue. Everytime the gun malfunctions, they shrug their shoulders, and hand the gun to me to “fix it” for them. Some child trying to clear a rim fire cartridge that has been struck (but not hard enough) is real dangerous. A hang fire is rare, but if it should happen, then it’s going to be hard to explain to their parents why their face likes like a pizza. And you know how impatient kids are. If you are not watching them like a hawk ( I do ), they aren’t going to wait very long before they try to clear the misfired round from the gun. Who do you sue? the gun manufacturer, or the ammo company? I don’t want to need to find out. Guns should work at least 99% of the time. What would the people at Colt or at Umarex think of G.M. if their car stopped running half of the time they drove it? And then we blame it on the brand of gasoline they use. And they are using the same gasoline that they have used for years in all their other cars. They would be livid. Well, that’s exactly what they are doing to us. Blame the ammo. Blame the dopey consumer. They are just making sub-standard guns. The military knows it. That’s why they lost a long-running contract with them. Colt will probably be the next company to file bankruptcy. And this Umerax .22 will be one of the anchors that drags them to the bottom. I know that writing this will upset some people. You can disagree with me all you want. But let’s all stick to talking about guns, and gun companies. Don’t launch personal attacks on me. I have nothing to do with the fact that many of these guns don’t work. Let’s talk about guns, not about people.

I found what may be a cure for some, not all, of the loading problems.
First I have found some ammo to be 100% reliable no FTF or load issues.
Every Federal load is this way and recently I found black box bulk Winchester target to be another reliable load. Yesterday I was sighting in with the Winchester and after 6 10 round mags I started to get failure to FTF with a new full mag. I found this strange, I remembered loading this mag fairly quickly not paying too much attention as to how I loaded the mag. The next 10 times I loaded that mag I was very careful in loading mag and continued with no FTF.
Conclusion, carefully loading mag, checking alignment of each round eliminated all FTF issues. At least with the Winchester.
I suggest trying this on some of your loads that have FTF issues.
Tim
MGB;
I am glad that our tax dollars are continuing to allow you to purchase products. We all know how well GM has been managed over the years. Have you ever worked for either of these companies? Do you know why Colt does or does not supply the US military? You should state facts not your opinion. This is supposed to be about the Colt/Umarex .22 Rimfire rifle, not everything else wrong in the corporate world. Gun enthusiasts get on these blogs to chat/discuss about products and sometimes look for help, not to listen to someone on a soapbox. With your knowledge maybe you should try to help and not hinder.
QUALITY OBSERVER – “I do not work at Colt or Umarex”…. “I MAY BE WRONG”… …”this is merely an observation from an outsider”. These are all direct quotes from my previous post. By making these diclaimers, I feel that I was just giving my opinion. If I am not allowed to give my opinion on this blog, then why does the administrator keep posting my comments? “Just the facts, maam” was for Joe Friday. If opinions are not what you want to read, then ease your mind, and don’t read my comments. If you see a posting that I made, just don’t read it, if my opinions bother you so much.
Enough is enough.
From here on in any comment on this blog post not about the Colt / Umarex M4 will be deleted.
tried the Winchester 555 box of ammo today and shot the entire box without one dud! Later I used the gemtech adapter to mount my silencer and it worked perfect! If anyone is going to use a silencer call gemtech direct and order the adapter.
I have 2 of the sights, one red dot the other has red illuminated reticle. Both work fine, one of them is on sale now at Midway.
If you having feeding problems try Winchester or Federal ammo and carefully seat each round in mag. I pull spring down just enough for next round, let the spring up to seat that round and then back down for the next. No feeding problems with the above ammo. I had issues other brands especially Remington.
Tim
Hi all. Tried my M4 yesterday. Per my original post I had problems with the rifle shooting way to high at 50 yds and to center the impact, the rear sight was almost against the right stop. So………..
1) Called Umarex about the elevation and they sent me a new (higher) front sight post. That fixed the elevation problem but did not change the azmuith problem.
2) Tried the handle from my real 5.56 Colt and was back to the elevation issue even with the higher front sight post.
3) Ordered a handle from UMAREX. …..Great! Resolved the elevation problem AND the azmuith problem. Makes me think the rear (original) sight was off center. The handle is definitly lower and this is what resolves the elevation issue. As far as the azimuth issue…it must be centered on the rail better.
Anyway, both issues are now resolved and at 50 yards the rifle can break paper using Federal GM. Eats anything I feed it from El Cheapo 36gr to Remington Target and Fed GM. Also Remington High Velocity with no failures. I would now say I am happy with the rifle and think it will be a lot of fun. BTW I put my older 3X20 Colt scope on it and it works just fine.
Hey Bob, just a little down the page on this link :
http://www.quarterbore.com/nfa/lightninglink.html
There is a picture of 3 bolt carriers. They say don’t use the regular AR15 bolt or else mill down the BC. Is this true?
Also, I wrote to firearmsblog to get Quality’s ip banned but they haven’t responed yet. The guy comes in here with out ever talking about the Colt .22 and his first post is talking trash like he knows everything. I bet he doesn’t even own one. I would just ignore him if he doesn’t get banned. Thanks for the email!
Hey Beltfeeder. Which gemtech adapter did you get? Just the A2 flash hider with the two left and right lugs?
My apologies to all.
Well, the more I shot my new S&W M&P15-22 alongside the Colt, I became increasingly more impressed with the S&W. The trigger is a lot nicer and has a much lighter pull than the Colt. The difference is not even close. The fact that things like the trigger assembly and pistol grip are all interchangeable with the myriad of AR-15 upgrade options is a real plus. I addition, I like the much heavier barrel, the functional bolt release, ease of disassembly and cleaning (very much like a real AR), and the solid feel. Umarex may be fairly responsive now, but what about in the future when there are a bunch of mal-functioning Colts out there? S&W’s customer support is legendary, and sets the standard by which others can be judged.
Bottom line, I took my Colt to the local gun show and traded it. Dealers were telling me that they have come down in price quite a bit since they first came out. I traded for a 2nd-gen GSG-5 with telescopic stock and HK rail clamp option for optics mounting. Given the plethora of seemingly pleased GSG-5 owners out there, and the breadth of accessories, I felt that was a better addition to my collection than a 2nd AR-clone — especially one that I probably wouldn’t pick up any more after buying the S&W. Fake parts, loose assemblies, and parts that fall out upon cleaning the weapon bother me. A firearm that is difficult to field strip and clean won’t be my first choice when I go to the range. The accuracy wasn’t all that much better than the S&W, so I am comfortable with my choice. Sometimes that’s the price you pay for wanting to be the first one on the block with the next new firearm.
I wish everyone the best and continued enjoyment with their Colts. My decision made good sense for me. If you haven’t bought one yet, seriously consider all the good alternatives that are out there. For me, it was the S&W M&P 15-22. Now if only I could find some spare mags….
Ed I can certainly identify with you about being first kid on the block.The only thing my colt M4 has gotten me so far, is a close repore with my local UPS shipper. I am on my third time sending mine back now and am either going to wrap it around a tree if it doesn’t function or try to get something out of it on trade.By the way have a GSG5 that I’m well pleased with.To the administartor;thank you for providing this forum so that people can express their frustration to others like me. I work hard for my money as I’m sure a lot of others on here do. To pay 600.00 for a non functioning trinket is very disheartning.S&W is looking really good to me right now.
well got my colt m4 22 back from umarex and its still screwed up so i traded it back where i bought it iam gonna go with the gsg -5 i think these colts suck iam sorry iam not im pressed thought it was a cool idea when i first saw it but now as far as iam concerened all these guns are a good 600.00 dollar paper weight and thats it so i couldnt take they aggarvation of it so to those people who are still trying to get theres fixed good luck you will need it
Thanks for all the feedback on the colt/umarex .22. I was in the market to buy an ar(.556) and did not want to pay the higher prices that they are brining right now. So I figured I would go with the colt .22. Ar looks and cheap .22 ammo, could not go wrong with that. UNTIL I found this forum.
Now I am not going to buy one with all the problems reported here.
Thanks again, you guys saved me $500 +.
Helex
What ammo are you using. Even my worst feeding Colt would devour all the Federal ammo with no miss fires or FTF. Even after I had them fixed Remington of any flavor is a no go. All the Winchester I tried also worked 100%.
Tim O
BTW I have 2 Colts, 1 S&W, and the GSG5. I like them all but for different reasons. The easiest to clean and hoot to shoot is the S&W, the GSG is a favorite to just plink with.
I just recently purchased my Colt .22 M4 OPS and LOVE LOVE LOVE IT! Here is my TOP 10 Reasons why everyone should by one:
1. MATCH GRADE CHAMBER: Due to the match grade chamber or, ZIP Chamber as they call it in Europe, it only prefers the quality ammo but not necessaryliy expensive stuff though. It shoots Federal, CCI, Wolf, and most of my Winchester very well. Once i made the bolt adjustment Umarex recommend it worked like a dream.
The easiest way to make since of that is look at is if it is a car – Try to run crappy gas in lamborgini or don’t bother tunning it either” – it won’t run for crap even though you just paid $300 grand for it. Great things take some TLC.
2. Accuracy: It is also extremely accurate – dime size groups @ 25yrds with open sights. Can’t wait to get a scope on it.
3. Materials: I love the fact the upper and lower receivers are sturdy Aluminum and not plastic like the “others” currently out and most of the other parts are made out of heat treated steel.
4. Barrel: it has a LOTHAR WALTHER barrel in it!!! Great barrels!!
5. Parts: All the parts/pins/etc are extremely tight – not sloopy or loose
6.Magazine: smoothest spring on an AR style mag I have ever felt
7. Threaded barrel: I can use my Walther P22 silencer on it without an adapter
8. Fun: I can go out and shoot all day and spend 3/4 less $ than if i took my .223 out – Cheap to shoot!
9. Accessories: They have all kinds of stuff available for them. I got on the website listed on my paperwork in the box just to take a look. They have a few videos about cleaning etc on there too. – Very helpful
10. Umarex USA: I called them before i bought my M4 and kept a couple of their people on the phone for a long time a couple of times asking them every question i could think of and they answered everything (thats how i know what the materials are and about the lothar barrel and such – I made a list of stuff i wanted to know before i spent that kind of money) they were nice and informative and they told me if i ever needed sevice or parts they would take care of me so my impression is they stand behind their product which means a lot to me as a buyer.
I recommend this rifle to EVERYONE and I hope that some people don’t avoid buying this rifle just because a few people have had small issues with them, not to say it should be expected or excused but, out of the thousands i am sure they sold, 3-5 people with issues is extremely great for a new product. (look at Ruger – they have recalled almost all of their new models they have released the last few years but they still make a great product)
Besides from the feel i got from Umarex they are going to take care of any problem that could arise – so no worries and HAVE FUN SHOOTING cause i am!
I know there has been a lot of negetive reports on the colt m4, but I purchased one about two months ago, and I love the gun. I dont expect a good gun like the m4 to shoot cheap shells like the remington bulk pack. If I wanted to shoot cheap shells I would have bought a cheap gun. I only use the cci mini mag and have no problem with the m4. I never have a missfire or a bad feed problem. The accuracy of the gun is excellent, and with the nikon scope I have on it, makes it a deadly machine. I may have lucked out and got a good one but I would recommend this gun to everybody.
Almost a month now since my purchase and 3 range sessions later and I still love this gun……get it, try it, and I bet you’ll love it!!!!!!! It is shooting spot on without fail…..
I just purchased a Colt .22 M4 and had some initial problems with it. It is supposed to be factory set for Standard Velosity .22 but mine wouldn’t cycle cartridges. I had 20 Jams out of 35 using Remington, 7 out of 50 using Winchester and 5 out of 50 using Federal. When I tried to make the adjustment necessary to set the ammo type, the first problem I had was removing the pin to access the adjustment screw. The manual doesn’t tell you that you have to open the flash surpressor 1 1/2 turns before you can knock out the pin. Once open, I found the adjustment screw to be protruding several turns rather the being flush. I turn the screw all the way down as suggested and since then have had no problems with Winchester or Federal ammo. Remington still hangs up and acts as it the lead bullet is slightly too big for the bore. Remington will go in about 3/4 the length of the bullet and stop. You can manually push it in the rest of the way and it will fire. Don’t use Remington. I currently using Winchester standard velosity and Federal high velosity with no problems. Since I have all of the bugs out, it really is a fun gun.
I also purchased a Colt ops. It’s a great looking rifle, But have had the same problems as everyone else except my forearm rail rotates on the Barrel. There are two allen screws that won’t bottom out to the Barrel to lock rail in place. Also when you fire a full clip to empty, the breach should remain open. It doesn’t. I have sent my rifle back to Umarex today after firing about 300Rd’s through it. They were very nice on the phone. Time will tell if they fix or not. Will let you no in the future what happens.
Good luck Bear I’m on my fourth send back for my m4 ops.

Please do not ruin this page for everyone else. If you have a problem with Umarex get in contact with them, I am sure they will be happy to discuss it with you and sort out any problems.
Trigger pull at 7.25. NEVER had a pull so rough.
Colt M-4 22 cal. : New gun – bad tirgger, new gun now at the gunsmith for his comments. Sorry I paid so much for so little quality.
happey with gun now just need full auto concerson never misses with federal 510
After reading horrible reviews of the M4’s, I decided to buy one…
I’ve had my M4OPS out to the range a few different times…
The first time out, I had a few stovepipes and light strikes with the Federal 550 pack… No biggie… I was expecting it… I only regret buying the 10,000 rounds of it before having the rifle… It fires from the 10/22’s just fine… Problem 1 solved…
Took the upper off, did a major cleaning of the bolt, and reassembled… No bolt adj’s or talk or “the screw”…
CCI minimags work without flaw… Winchester SuperX works just as well… 7,500 rounds, boresnake every 1000, and cleaned at the mid-point… 1 light strike and zero stovepipes…
The only problem I’ve had thus far is optics. I wanted a dual sight set-up.
Iron sights out to 100yds, red dot at 40.
The front sight overall is too tall for a red dot or most any optic without removing the front sight in favor of something flip down… $60-90 for the Umarex flip down front… Or $100 for Troy… No brainer… Still haven’t bought it though.
I’ve searched and searched for see-thru picatinny risers and couldn’t find one tall enough…
FFL/Gunsmith mounted his spare Trij ACOG on it, and it worked for what we were doing…
The magazines don’t seem to stand up to heat as well as they should… The plastic lips close to the chamber seem to melt ever so slightly. Nothing major.
We’re working now to design a mod for them to replace the lips with machined steel… Let you know when that comes full circle…
I was a GSG snob at first, but after handling the plastic S&W and polymer Sig, I am happy to own my Walther made Colt M4OPS.
Hello to all colt M4ops owner’s. The time has come to inform you of my new experiance with Umarexusa. I sent my rifle back for adjustment’s and they returned with a nice little scrap on it back to me. I was a little bit Pissed Off at first. Because it was brand new. Then I shoot about 160rd’s throw it today. I must admit it worked perfectly and all problem’s vanished. They also sent me a extra mag with it. I must say those guy’s at Umarexusa are Ok. I am very happy now. Some of your comments online scared me that this company would not take care of it’s customer’s with problems. That is not true. They do take care of the customer I am living proof. Good luck to all and happy shooting. I am glad I bought Colt M4Ops It’s great!
Well I have to pile on with the disappointment of this weapon. Had the same feed and extraction problems many have commented on. I sent it back and recieved courteous and quick customer service from Umarex. However first time shooting it after I recieved it back it now doesn’t load the round fully into the reciever about 75% of the time and had several light strikes of the primer rim. I am going try different ammo and see how it performs. Will post more after I change the ammo.
I have for some time been considering a .22 upper for my M4 type AR-15. Recently at a gun show I made an impulse buy of a .22 “Colt M4” carbine instead. I took it home and went over it and immediately discovered that I should have spent more time with it and examining it prior to purchasing it. It is not a Colt and although Colt claims on its website that the rifle is produced by Walther mine is stamped as being produced by Umarex. I am not sure what this tangled web is or what the relationship is between the companies. Umarex is a company which builds air soft guns and you can see the heritage in the design and quality. I am disappointed that Colt would stamp its name on this rifle. I have found Colts in the past to be of high quality. I made some dead wrong assumptions that this rifle was set up similar to M4 .22LR uppers that I had considered purchasing several times. Upon close examination of the rifle the functionality becomes frustrating. First of all the safety lever is flimsy and mushy. It requires 180 degrees of rotation from semi to fire instead of 90 degrees as is standard with the AR-15/M16/M4 series of rifles. This is a major issue for individuals who constantly manipulate the safety and practice firing drills that began and end with the weapon on safe. The second thing that I dislike about the weapon is the bolt hold open. I have to caveat my statements about the bolt hold open lever by saying that I have not used any other rifles like this and it is possible that my weapon has a defect. The bolt hold open looks like it should be functional however it is not. The bolt locks to the rear after the last shot is fired from the magazines however the only way to lock the bolt to the rear without a magazine inserted is to place your finger in the magazine well and push up on the bolt stop. The AR type leaver on the side it is only eye candy and just takes up space. The bolt spring is the weakest that I have ever seen in a .22 and constantly refuses (with .22 Remingtons) to close the bolt far enough to chamber a round. You will be farther frustrated if you tap the forward assist because it does not function either. The dust cover is also flimsy and you really have to thump it to make it lock in the closed position. I liked the idea that I had purchased a weapon that could fire the cheapest ammo. I went to Wal-Mart and purchased 500 rounds of 36 gr. Remington Thunderbolt ammo and headed to the range to try the rifle. The magazines are probably the best part of the rifle. They are simple to load and allow you to depress the magazine follower and go easy on the thumb. After loading a couple magazines I settled down to some shooting. The rifle absolutely refused to chamber the ammo and I ejected 8-10 rounds before the rifle fully chambered one round. The round fired and the rifle returned to its previous state in which I could not fully chamber another round. Finally I secured a box of 40 gr CCIs from the truck and tried them. They functioned and cycled correctly though the rifle. The .22 Remington have a bad reputation however I was subsequently able to fire two 25 round magazines though my wife’s 10/22 without a single malfunction (while she reminded me the 10/22 cost $197.00 at Wal-mart which is much less than the $598.00 I paid for the “Colt”) so they should be adequate. Maybe it simply requires some experimentation to determine the correct ammo but I am not satisfied with the rifle or its performance at this point. When attempting to strip the rifle down I was also disappointed by the construction materials and the effort necessary to remove the rear receiver pin. I have not had the time to get back to the range with the weapon and frankly I am not sure that it would be worth the time. Presently the “M4” occupies a spot in the back of the safe where it will most likely stay until I feel adventurous. It will not be the tool that I had envisioned it to be. I am disappointed with the rifle. Simply put it is a toy and cheaply made at that. If you like smoke and mirrors and want a fake gun to mount fake optics etc on then this rifle is for you. If you want a rifle with same controls and function as the AR-15/M16/M4 series of rifles leave it alone. I am not turned off to the idea of a .22 AR but do some research and no impulse buys.
Howdy James — I made a similar impulse buy, and was initially fairly pleased with it, despite the design idiosyncracies, until I tried to strip it down for cleaning, or to add other AR-type accessories to it. I only fired CCI and Federal bulk ammo through it, so I never had any FTF issues. I got increasingly concerned as I read the blogs of the many others encountering problems, and having to send their rifles back to Umarex — some multiple times.
I also purchased the S&W M&P15-22 shortly thereafter and fell in love with it. The controls are were they are supposed to be and function like an AR. The trigger pull is crisp and much lighter than the Colt. Accessories are AR-compatible all the way down to the trigger group. Take down and cleaning is just like an AR. It eats all ammo I run through it — even Remington bulk. I has a match-grade barrel from Thompson, not a soda-straw barrel inside of an aluminum sleeve. Best of all, it feels incredibly solid, and of quality design, fit, and finish. Oh yeah, it’s also made in USA….
Bottom line, I chalked my Colt purchase up to experience gained, and traded it shortly thereafter for a GSG-5, which has also been flawless. I got rid of mine while they are still a bit of a novelty, and hence, still held a bit of value. I feared that the longer I waited to trade it, the less valuable it would become, as word of such issues like you and others have had continues to grow and circulate. Of course, I am just a data point of one, but I can certainly empathize with your situation.
this gun is on my top gun list. I have had a few like strikes and two ejections problems, but still like very much. Does anyone else have problems with the dust cover not snapping closed though?
Andrew — mine never would snap closed — it always stayed open. Seems it was another one of those parts that was merely cosmetic.
Well I had a chance to run some CCI ammo though my M4 yesterday and it fired flawlessly. Any brand of Remington ammo jammed it up though. Called Umarex and they verified do not use Remington ammo. In all, I had higher expectation of this weapon. For the money spent ($569) the reliability and finicky ammo issues I would rather have dressed up a 10/22 and been able to dump ammo all day without worry. If you have low serial number weapon ( mine is in the 3000’s) you may want to call Umarex and request a new owners manual. When I spoke to them, they said there had been many changes from the original one shipped with the first series of weapons and that they would send an updated one free of charge.
ps: Andrew ejection port cover is purely cosmetic another question that Umarex answered on my phone call.
I recently purchased the M4ops and ran 500 rounds of cci with no feed problems, only 3 duds. I attempted to shoot some remington ammo and had 60% fail to feed and fire. A couple years ago I had a failure of remington ammo in a 9mm HI-Power in that the loads were too weak to work the action properly. I would not recommend Remington ammo for any firearm ever. Many of the .22 bullets were loose in the cases. Maybe made in China? This Rifle Ser.# in 21k range, no complaints yet.
Man I wish I had done a little more research before buying! I have a Walther 922 with a Gemtech Outback II ans wanted a rifle I could swap the can over to. When I saw the M4Ops at Academy I thought it seemed like a pretty good deal, it felt sturdy and the threads would work with the p22 bushing. so I bought it… had a box of thunderbolts, and subsonics by Remington…and of course had FTF 90% of the time. I have the same issue with the Mag Release as described it doesn’t fall out but the slightest pull on it will break it free from the mag well. my overall opinion at this point is, I paid ~$600 for a cool looking piece of trash… I will try some other ammo later today, but if I specifically bought it for use with the Outback can, so the having to feed it HV rounds is a bit counter-productive. I loaded up some Colibri rounds as well, knowing the wouldn’t cycle the action, but assuming I could hand cycle them…. nope, the ejector doesn’t reliably grasp the rim of the Colibris.
I will file down the topside of the mag release and try the other type of ammo, if anyone has had any luck with subsonic rounds please let me know the type… If I cant find any that work, this little colt will be for sale. I guess if you aren’t using a can, and you have the right ammo that feed in the match barrel its probably a great little plinker…
hope someone has found some sub sonics that will feed and cycle reliably
-J
Jason I hate to tell you this but I just recieved mine back after the 4th time back to Umarex…It will fire cci now maybe 85 % of the time but will not cycle any of my subsonic stuff..I have a Waith supressor also that i had great dreams of shooting on this gun..I have a GSG 5 Pk that works great with the remmington subsonic stuff.Good luck to you.
m4noop, have you tried CCI Subsonic HP ? It is the only subs I use on my .22 guns.
I’ve had a few feeding and stovepipe problems with my M16, called Umarex and found my charging spring was not adjusted properly. 9 turns in from flush for High Velocity ammo. I also discovered since the bolt carrier is in 2 pieces (what a design DUH that was) that one side was just a hair high on the back side and was not allowing my magazine to sit flush. I ground down the top surface of the mag. It now seats perfectly and have not had a misfeed after about 800 rounds. I’m calling Umarex with my results. They also sent me a mag release ??? There is nothing wrong with the one I had.
I’m using CCI HV, Aguila Interceptor, Federal #510 Champion with no troubles. I even used Remington cyclone just to try them out with no trouble.
KEEP IT CLEAN. After 200 rds I clean off the feed ramp and all around it. And run my bore snake once. When I get home I give the action a foam bath and blow it out with compressed air.
I agree the price was alittle high. I paid $650 for mine but it is a great plinker and everyone who tries it out loves it as well.
Gentlemen, all comments were of value to me. I too had some difficulty 1 st. Time out with 50. Percent ftf’s! However as in all new products once the “bugs” are worked out then it is good range rifle to bring the spouse out to. As a former usmc officer. And a current officer we have to remember we all are enjoying our 1st. And. 2 nd amendent rights as americans. Right? Good shooting all of you great americans. God bless you guys! Dr. Commander.
Just purchased the Colt M4 ops .22lr, “Still in the waiting period”. I have 100+ rounds of some 20 year old High Velocity CCI ammo I am waiting to put through it but was wondering what would happen if I did not adjust it for High Velocity before using? It won’t shoot as fast or what?
Garett,
You will have misfeeds and possible stove piping. Your Colt comes with a allen wrench to adjust it. Very Simple, remove rear pin for upper half, allen screw in the back of the action, turn ‘in’ 9 turns from flush and your done. Keep it clean and clean the feed ramp as soon as it looks dirty.
Has any gunsmith been able to do anything with the trigger pull of 7lb’s
If Colt had taken the upper and lower all metal from there 22 AR and used S&W trigger assembly, upper bolt assembly and there barrel from there 22 AR they would have had the top and most trouble free 22 AR out there. And would not have the bad reputation they are getting now and mfg. Cost would have been lower.
Well I am back to square one, The colt went back to the Manufacturer. This is second count of problems and very pissed off. I just returned from my gun dealer with great news. He said he would take back my colt M4 oops and give me store credit towards a new rifle. I am very pleased with that option. I really wasn’t satisfied with the preformance of the colt. I just didn’t need another show piece in the safe. Owning one of the Colt/Walther rifles is like owning a old motorcycle some time it works perfect and sometimes it doesn’t. Good luck to all of you shooter’s and thank you for this Web-Site.
I posted in July when I first got my M4 Ops…I said I loved it then and I still do after 10,000+ rounds fired. We have since purchased a Colt LE 6420 and still like to shoot the .22 just as much. I just wanted to give a positive plug for a gun that has been very,very good to me and my boys.
I have had the M4 now for 2 months and around 5000 rounds. The gun has been shot by a number of members at the local range and everyone loves it. I have shot everything from RWS to Federal to Winchester and maybe 5 hung up cases. I have not shot Remington because of the comments on this and other pages. I have found the gun to be accurate and a blast to shoot. I have a Bushmaster A2 and a DPMS National Match. I can practice my offhand with twice the shots at half the cost. I can’t wait till my Grandson is old enough to teach him to shoot with it.
I purchased a Colt M4 .22LR about a month ago and have put close to 1000 rounds through it and I have found some things that I really like and I just recently stumbled upon a couple of things that really honk me off:
Likes:
1. Once I got it dialed in, it shoots like a champ and is a blast to shoot!
2. I have tried CCI and Winchester 333 and it seems to like those quite a bit, although I think I need to adjust the slide speed because I still suffer from the occasional misfeed/failure to eject/etc.
Dislikes
1. Like others have mentioned, I had to run my front sight post up quite a few turns to bring my rounds down. It was shooting at least a foot high at 60-70 yds. Umarex is sending me a taller sight post when they get back in stock.
2. I had to go quite a few clicks to the right on my rear sight aperture to get on paper too. The rifle shot way left out of the box. Umarex said that I might need to adjust my front sight base because apparently they have had issues with them moving during shipping.
3. Still getting an occasional misfeed/failure to eject/etc that I need to adjust for.
4. The trigger pull is almost painful after a few hundred rounds. I want to take it to a gunsmith to see what they can do.
5. Aguila high velocity ammo seems to shoot very high even though winchesters are dead on. not sure if it is the smaller bullet weight or the higher velocity but it looks like it will require a re-zero to shoot this ammo in my rifle.
This really chaps my a$$
I wanted to improve my iron sights even more so I purchased a . 050 NM DCM front sight post and a .030/.040 NM rear aperture thinking I could really get dialed in with my irons. When I received the new sights, I excitedly set about removing the OEM front sight post and screwing in the new one. Only the new one was too thick and would not fit. %#^@%!! Oh, well I thought. I can at least put on the smaller rear aperture, so I took the OEM aperture off and tried screwing the adjuster back in. Again, the adjustment screw was too large to thread into the new aperture. ^#%$@#$!! I have thought about purchasing a replacement AR front sight base and an AR handle but I am worried what new headaches I will run into with that. I thought some of these parts were standard AR parts but that doesn’t seem to be the case.
All in all, I like the rifle, but it will most likely be much better once Umarex gets all of the kinks worked out. It would also be great if they could use standard AR hardware so you could swap stuff out easily.
I hope this helps others.

I was really worried after reading all these posts. I was very reluctant, but purchased the OPS model Tuesday, September 29th. I have now run about 600 rounds through the rifle. I have used Federal 711B, WOLF target, Federal AutoMatch and Eley SPORT. All have worked very well. The AutoMatch is high velocity but I didn’t have to adjust the spring to get it to work, it worked fine with the spring set for standard velocity. I have had some Fail to fire rounds with the Federal 711 but it was not the rifle, the ammo is many years old and have the same problem in my bolt action target rifles. I mounted a Leupold Mark 8 4.5X15 to fire for accuracy. The WOLF shot under 3/4 of an inch (outside edge to outside edge, not center to center) at 50 yards. VERY VERY ACCURATE RIFLE!!! Terrible trigger 10 to 11 pounds when measured with digital trigger pull gage. The front sight post is too short, so with iron sights it shoots high. Will have to call for a replacement. One interesting thing I found was that the .22 BoreSighter spud would not fit the barrel when I tried to sight in the scope. The Walther bore was just to tight, I kinda’ like that. I also like the ‘match chamber’. Like I said earlier, very accurate rifle. I don’t care if I can’t shoot super cheap crap ammo. I would rather have an accurate rifle then a rifle that would shoot cheap junk ammo that also gives 2 inch groups at 50 yards. I am extremely pleased & happy with it and am already thinking about buying the rifle version that has the flip down sights. I am going to try to figure out how to improve the trigger and get it down to about 3 or so pounds, but the trigger is about the only thing I have any kind of problem with. Really happy that I bought it.
Just got back from the woods. I fired another 500 rounds. Really, REALLY like this little rifle. Even with the 10+ pound trigger you can fire REAL fast. But still really want to lighten the trigger up. I have ordered one of those Walther Red Dot scopes and 4 extra magazines and am looking more & more at the pictures of the M16 SPR model. Should I or shouldn’t I???????
I bought the M4 ops on Sept. 22 and I finally got to shoot it yesterday, I have used 100rds each of American eagle HP, Armscor standard velocity and Remington golden bullet,first i tried the Armscor & it flawless then I adjusted the bolt speed spring to high velocity I used the American eagle & i had 4 FTF then lastly the dreaded Remington golden bullet which i also had a bad experience with my Walther p22 & to my surprise I only had 3 FTF & the 3 that didn’t fire I notice that the slug was too loose on it’s casing…all in all the only problem that i encountered was the FTF which wasn’t the gun’s fault but it was the ammo…I’m very happy with my M4 ops.
I put a Walther P22 thread adapter on my Colt M4 .22 and my .22 suppressor with 1/2-28 fits great. It even will cycle wilh sub-sonic ammo.
The is the only gun I take to my range now
Capt. Perry
Purchased the M4 earlier this week for my wife, first day out today. Remington ammo failed miserably – especially the Golden Bullet, 0% success. Thunderbolts were not good and Viper was Ok, but 2-3 duds per clip. CCI mini mag worked best, but I still have work to do. Plan to try some Federal, and Winchester ammo next time out.
Sure gets dirty, keep it clean – especially the ramp, had a few jam on the tiny, tiny lip where ramp and barrel meet. May take sandpaper to it? Figure I’ll adjust the screw first and see how that works. Could be a cycling thing.
Overall, about what I expected to better than expected. It’s a blast to shoot, seems to deliver a good punch. Figure I’ll just have to devote a little time to tweaking her in.
Got the M4 Carbine , had the usual remington ammo problems as everone else but the winchesters worked great. Have yet to adjust the “screw” so will probably try that before I cycle CCI mini mags.Iron sights were right on out of the box,too much fun! Did’nt pay a huge amount 499.00 + tax & dros but even with ftf from the remington ammo it was a blast to shoot. Does anyone know if a two piece rail hand guard such as a Troy will fit direct in place of the original hand guard on the carbine.
Just bought a M4 and WOW…. What a fun plinker… I’ve only ran about 200 rounds through it and had one mis-feed of a Thunderbolt… (My marlin don’t like them either…LOL… was trying to get rid of the last 20 or so…)
Very Accurate with the Wincherster X ammo. Now I’m looking for a see-thru riser to mount a red-dor optic on this thing…
Joe
I went to the range again today and tried some remington thunderbolt ammo that i bought at bass pro shop last week (that’s the only ammo they have) i bought 5 boxes of 50 rds for $1.99 a box and to my surprise it was flawless, also i got a box of fiocchi super match from tunners outdoor sportsman for $8.99 (ouch!!!) and it was dissapointing coz for the price i was expecting it to go well… I had 2 FTF n 1 stove pipe out of the 50 rds, good thing i just bought 1 box just to try them out, i hope i can get my hands on some cci, federal and winchester ammo next week to try them out on my next trip to the shooting range….i still had a blast shooting my m4 ops.
I did some more testing this week at 50 yds with a red dot, my eyes are terrible with out. I was using black box winchester HV 40 gr and they were grouping at 1 moa consistantly. I had never seen this with this carbine, do not even remember the rifle version doing that well. I will take rifle back to range and repeat with this ammo. I also had the GSG AK, GSG MP5, and S&W none matched this grouping with this or any other ammo.
The Colt rifle with target scope did this with CCI standard ammo if memory serves, but have not seen any of the listed guns and cheap ammo preform this well. Had no feeding or FTF issues with this Winchester ammo. I did have some Winchester 36 gr HV and it was not doing as well.

I love the look and feel of Colt M4 22Tactical rifle. But felt it was a let down. It is a very expensive little plinker. I am just a kid at heart with dreams that things should work right. The problem with most of all 22 Rifle and pistols is they just don’t preform. Looking backward in time I remember 22’s like remington nylon 66 and Ruger 10/22’s and Sears Ted Williams model 22’s. You could fire almost any ammo throught them and the quality of the gun would last a life time. What happen to well made products that worked. I just don’t know. Thanks to this Web-Site it makes it possiable to communicate about the pit falls of poor weapon’s that we purchase. I myself have sold my Colt M4 to get a Smith&Wesson Mp15 22, From what I have seen on U-Tube and read here it seems tobe the hot 22 rifle for now.
Need a mid-range (price) red dot scope for my carbine. Who’s got a decent one???????
i have the m 4 22 umarex have had a little trouble with ammo i am still trying different brands. can any 1 tell me hoe to adjust the set screw . i read where some of u turn in nine turns from where do you turn from, when the screw is flush or when the screw is alol the way out. also does anyone know where i can by a front quad rail, umarex sells one for $220.50 witch is almost half the price of the gun. i tried the one from cheaper than dirt but it would not fit because ots for a ar 15 223 ect.
First thanks for having this forum. I have bought a Colt M4 22Tactical rifle. I live in Alaska and I use my 22’s for what they are intended for, small game and plinking. I’ll still think this gun should of cost $100.00 less.
I removed the front sight/removed the rear sight, put on a picitiny rail adapter with a BSA 4 power scope with steel rings. Very accurate out to 100 yrds, I am quite happy with all the table fare this gun has provided me in the last 3 months. I shoot cci seconds. I have yet to have a fail to fire when my gun is out hunting.
Shoot the same ammo. Try others at the range. The barrel had unsightly 2 drive pin slots from the front sight, easly solved by adding 1 foot of black duct tape wraped around the barrel for emergency use. Never gets hot because the inner barrel is the bore. Rabbits, ruff grouse potato and carrots…Is’t that what it is all about? Great sight…..I’ll be back.
Ok…. well over a 1000 rds and still a absolute hoot to plink with….
from my limited experience….
Thunderbolts work near flawlessly (1 misfire, 200 rds)
Winchester Wildcars work flawlessly (0 misfires, over 600 rds)
Remington Vipers ( 1 misfire…. 14 feed issues, 100 rounds)
CCI Mini Mags ( 0 misfire, 300 rds)
Winchester X (7 misfires, 50 rds… but man what a little bitty group….)
Gun show el cheapos Spanish name… spanish writing …. (3 misfires, over 200 rds)
CCI Mini Mag Segmented Ammo ( 0 misfires, 50 rds)
I come by the wildcats pretty cheaply and easy and will probably stick to them… but have a lot of other stuff to use up…. the Vipers are pretty consistent, very tight group (small thumb size hole at 50 yards) but refuse to feed properly. This is probably due to their stepped conical shape.
Amazing how fast you go through 22lr when you loading 30rd clips…
Vandal
ps. nearly every misfire of mine…. came during slow methodical firing…. 1maybe 2 came during fast as I could pull the trigger firing….. hmmmmm
Double PS….
after two cleanings and all the ammo that has gone through it…. the problems seem to be lessening….

I have the colt ops 22lr and love it and also, would like to ask if anyone else has looked for a see thru riser for it wiht any success? I have the standard tactical sight and front fixed sight, but would like put a scope on without losing any of my line of sight. dual sight set up. thanks billie
does any one know how to take the bolt out of the rifle ???? i know umarex does not want you to but i need to clean it because it gets real dirty and having it out would be easy
Purchased Colt 22rimfire NIB today at Kingsport, TN gunshow. I wish I had inspected it before I left. [I assumed the Colt trademark would be good enough] When I got home and removed it from the box I noticed that that the ejection-port dust-cover wouldn’t latch. The pin to “break open” the lower wouldn’t give to thumb pressure so I had to tap it out with a piece of plastic. When I hinged open the upper and lower, the latch release popped off and piece of plastic approx. 1cm in the shape of cube popped out onto the floor. This 1cm piece seemed to fit behind the bolt. I put every piece back in the box and will call the manufacturer tomorrow. There’s no way I’m going to shoot this weapon or sell it to someone else. I didn’t get a receipt from the dealer but will track serial no. down to get a refund. Caveat emptor………….
HOJO
All that is normal for this rifle and I believe covered in manual. Yes the gray square piece is the buffer for the bolt.

Welcome to the new world of Colt HOJO. Sorry to tell you but I was told by Umarex the dust cover is just ornamental,the release latch is ornamental,and the muzzle break has to be loosened a quarter turn to remove the pin. Mine after 3 times back to Umarex still will not fire a whole clip of anything without a misfire and now stays locked to the rear when empty ,requiring me to insert finger into bolt to manually release bolt stop. I have collected guns for a lot of years and this one is the worst new gun I’ve ever had the dis-pleasure of owning.If I didn’t have a conscience I would sell or trade mine in a second.
still waiting for anyone who knows how to remove the bolt from the rifle so i can clean it
I was going to make some custom displays for my local gun shop in trade for an umarex m16spr… I looked at the spec on the m4 and m16 and it shows 13.78 inch rifled length for both, the m16 has a 20 inch barrel, what gives? Is it useless to get the longer barrel or is there a misprint in the specs? I was hoping to have a nice companion to my M1S AR-15 in 545×39 / 20″ & FF tube for squirrel harasment. What would you recommend? Oh and thanks for all the great information, I think it took me an hour to read ALL the comments!
George,
With the rifle broken in half, unscrew the flash suppressor and remove it, now pull the changing handle back and that will pull the guts out of the rifle, bolt, breech, and barrel.
i am having so much dam trouble with all ammo even the ones that hang fire. the bullets look ok in the mag but when loaded into the rifle and thay still look ok looking in to the breach , when the trigger is pulled i hear that dam click, did not feed a bulley into the chamber / any one no how to fix this problem???? it happens with all mags
thanks
mikeon thanks for the information
mike do you have feeding problems, rounds not feeding after loading a magazine and then putting into the rifle ,pulling the chargeing handle then a click when the trigger is pulled ????????
george
George,
Take a look at the posts around the July time. A major factor in this weapon cycling properly is the ammo you use. Many folks have posted different types however most everyone has used CCI with success. Additionally I called UMAREX and they confirmed this and warned about using cheaper bulk amm like Walmart Remingtons and Winchesters. Also if you don’t have a manual for the rifle call UMAREX and get one sent to you. They are really good about warranty, however warned me about tearing down the weapon to far as it voids the warranty. I started using CCI’s and enjoy the weapon now but had much frustration before and had to return the weapon once to UMAREX. Good luck.
thanks john, i havent torn down the rifle yet tho . but i have tryed many different typs of ammo so far the last being spitfire and thay r not that good either. neither is h v aquila . this rifle looks great but what a problem. my gsg5 shoots everything but the problem also is it wont chamber a round most of the times before it fires only i click on a full loading of 10
thanks
Wondering where to find a 30 round mag for this gun. California gun evidently only has 10 rounds.
George Lack
Do you mean misfires/light stikes? You really have to smack the magazine in because sometimes it won’t seat. I’ve had issues with Winchester Super X ammo from Walmart failing to fire, but even worse luck with the Federal 550’s from Walmart. Using the 550’s I got about 5 fail to fires/light strikes per 30 round clip. In my opinion, they are garbage in my gun, they also leave a really gritty residue in my gun, like someone sprinkled a pinch of sand into the inner working of the rifle. CCI Mini-mags and the Mini-mag HPs work great though.
Bob
You can order them directly from the Umarexusa website.
Hi All, Just wanted to say some positives for the M4 Spec Ops. I now have had it since August and have fireda couple of thousand rounds through it. From reading the forum I must be lucky. I have no problems with it. It eats all types of ammo from Federal 36gr 550 paks from Walmart to Remington Target. I can say it does not like the Remington “golden Bullets” 500 paks. I have never adjusted the bolt spring tension to accommodate any different ammo.
Just on speculation, could most problems be magazine related? I know that I have to give the new mags a good smack to seat them properly but other than that…….
Just wanted to say a positive for the gun. It is fun to shoot!
bob thanks for answering i have had a lot of bad strikes with the rem . also stingers the best so far federal not soo good , spitfire not the best have had better strikes since i turned in the screw 9 times but most trouble with feeding . i agree the 30 rd mag stinks it lockes in but i can pull it out with out pressing the mag release even tho it seats in i bought two 50 rd boxes of stingers cci for $13.oo in wallmart bad huh ???? unbeleiveable what ammo is costing these days even .22s
I bought the M16 Spec Ops in September and have had a blast with it. Remington “golden bullets” 550 pack from Walmart do NOT work as others have posted. They do work in my 22 Kimber pistol, so the boxes I bought will not be a waste. Federal 550 packs from Walmart work great, but not as accurate as the CCI HP’s. I will use CCI for hunting and target. Then use the Federal for plinking.
The rear pin keeps creeping out on me and I have to keep jamming it back in place. I tightened the muzzle brake and that didn’t seem to help much. Is this a potential problem, or do I just take my rubber hammer and punch to the range??
Put a Leupold 2X7 rimfire scope on the gun and what a great combination. Overall, I am very pleased with this gun and have more fun with it than any other gun I own. My high powered rifles/pistols are getting too expensive to shoot, except for hunting.
to day at the range i fired .22s federal 500 pack, stingers, spitfire ,aquila and not one hang fire not one feeding problem. i think my trouble was the flash suppresser was too tight from the factory. tomorrow i will do the same execpt i will ad thunderbolts and federal in the red box will let you know tommorow
All I can say is I read all the negative after I bought the gun of course and thought I was well prepared before I went out and fired my M4 ops model. What a joke out of the box. Firing pin feather striking. Unspent rounds were ate up just fine by my 10-22. Problem solved. I did send the gun back for good. I am not willing to waste $600 for a chance that I might get a diamond in the rough when it comes to this boat anchor.
Alann,I’m glad to hear you were able to get your money back.I have sent mine back to thenm 4 different times and have another problem with my M$ now and they have not offred to refund my money. Going to the gun show this weekend and getting a good gun.
everything was great today, all fired flawlessly again all except thunderbolts but i never really like them too much before anyway. so ithink my troubles are over. must have been the flash suppresser was to tight from the factory
m4noop, I see a class action coming out of this down the pike. I can’t really recall ever hearing about a modern gun with so many flaws and repair tickets. I told the gun shop they didn’t have an option. They can eat it or Umarex can. It’s not my job as unsatisfied customer to figure it out. I was probably one of the rare ones to get my money back. When you spend over $670 on a new gun it better be flawless out of the box or you mine as well convert it to a toilet plunger.
sorry to hear alann that you gave up, i had the same trouble as you to a t . but losening up the flash suppresser and just snugleing it up was my answer to all the problems . now i love the gun .its a blast to shoot.
Maybe down the road after all the kinks get worked out and Umarex doesn’t scrap the guns I might look into replacing it. But for now I had to let it go. I only had my muzzle cranked on hand tight to.
Has anyone had the problem of the 10 round mags being REALLY hard to take out? I just ordered 3, and they are all really tough to remove. This rifle is slowly becoming a POS in my mind.
Nevermind….I figured it out and fixed it.
mike what did you do to fix it
george
mike how did you fix it ???????
george
I have shot remington ammo (350 rounds bulk) with no problems. federal ammo (500 rounds) no problems. I enjoy this gun much. Got mine at Gander mtn, had their gunsmith adjust the magazine clip after about 500 rounds as it was not tight enuff. great service there. Do not let the few whiners here keep you from enjoying this gun.
I bought an MP4 OPs .22L on 11-19-2009. Fired first shots on 11-20-2009. Stove pipes, failure to feed, failures to eject, fail to fire, clip falls out. Nothing but troubles. Using Federal SpitFire high velocity ammo. I would not recommend this gun to anyone. I have a DPMS DCM .22LR that rarely has issues and a GSG-5. (unless using Remington ammo). Planning to pickup a Smith&Wesson 15-22 and maybe a Ruger 10/22, throw this Colt away.
George Lack — I filed a particular spot on the magazine down just a hair. I can’t explain it without a picture.
Bradley Reese,
Few whiners? Feel free to look into more forums and ask around. Heck call Umarex and ask them how many guns came in this week for repair. It’s not a few! This is a wide spread problem. Talk about few? You are one of the lucky few. You got a diamond in the rough and not a toilet plunger. My gun shop was very aware of these mentioned problems not being an isolated incident and fully refunded my money after my gun decided to not function properly out of the box. Yes it was cleaned properly prior to it’s first outing, I used good ammo, my bolt speed was set properly. Now, when a firing pin does not engage the rim properly and you have fail to fires every fifth round, that there Bradley is not whining. I suppose you’ve never had anything malfunction in your life let alone posted your findings or reviews or told folks in person how disappointed you were about a certain product. You keep your clone Colt and I will let my Ruger 10-22s do the whining from now on while they are out performing and outlasting your gun by a long shot.
Whiner Bradley? Fist of all I am a gunsmith and I know a piece of junk when I see it . Yesterday was one of the happiest days I’ve had in a while. After sending my m4 back to Umarex 3 times, and having yet more problems upon getting it back,I traded it at a gun show for a MP 15-22. As of last night I had put about 400 rounds of various brands and velocities through this gun. I had only 1 faliure to fire on a remmington.This is the difference in a well made gun and a piece of junk. Congradulations on your luck of actually getting one that works. Read the post,go to a reputable gun shop, and see all the other whiners that expected that over 600 hard earned bucks would buy them a good rifle right out of the box.
allen you are right, i had a few problems but i was lucky thay are gone now. there is no doubt there is many many problems with this gun and there are some of us that are very lucky and when the gun fuctions and we know it.hopefully umarex will work them out for every one in time
I have just received the Sig 522 and comparing it to the gsg, s&w, urmax colts I also have. First impression is that it may be the best of the lot. The only minor gripes are: no sights are furnished, loading mags is a real pain.
Other than that it is a fine firearm, easy to clean, accurate and well made.
Tim
I was wrong with the whiner comment. Please forgive me. May all be safe and blessed this day and always.
After spending a day trying to tweak the Colt, I gave up. I also took many photos of the problems I encountered with the gun. I packed it back up and took it back to the store armed with photos. The store unfortunetly would NOT return the gun but did give me a new one. The gun was just not safe and the photos prove it. The serial number on the new M4 is higher and has a very different feel when pulling on the charging handle. I am hopefull. I also purchased a S&W 15-22. and already like the gun more without even shooting it. working bolt latch, better lower, safety selector is only 90degree versus the M4 a full 180degree (weird). Will post some results.
Any update on this rifles availability in Canada/whether it will be restricted or non-restricted?
Wow – so many negative feed backs on the Colt AR15 22. I purchased one several weeks ago and love it. I did have problems with it out of the box – failure to eject, failure to feed and failure to fire. At first I was very disappointed with my purchase. I called Umarex and they were very helpful. First step – quit using cheap ammo (remmington). Second step – break the gun down and turn in the fireing pin tension allen screw IN 9 full turns. Third, before putting the gun back together, clean off the garbage left in the feed area from the remmington ammo. I put the gun back together and purchased some Federal bulk ammo – and the problems were resolved. The gun is awesome, and extremely accurate, and reliable. As for you gentleman that whine – yes I said whine, about it not being a true AR, and AR parts not interchanging with it, you miss the entire point of it creation. It is built as a preprietary 22lr in the configuration of a AR15 – and Walther and Colt did an excelent ent job accomplishing that task. I also have a Rock River Arms (and love it), when putting the two side by side, they are virtually the same in appearance. Wheras the Smith and Wesson MP15 22 – in my opinion, it looks like Smith and Wesson pit less attention into their design, and with it’s polymer construction, fails to maintain the handling characteristics of a “real” AR15 – something that the Colt does a very good job at. Now for the reality of the situation, each person has their opinions and their “real to life” experiences. I have spoken with people from the gun shop where I purchase my guns, and they expressed displeasure in the Smith and Wesson for the same reasons as have been described about the Colts version. Each situation is as it is, but take the time to make the adjustments, clean the gun and use correct ammo. Incidently, shooting CCI Velicitors from the Colt is awesome, but they are more expesive than the Federal bulk ammo. If you have a Colt, enjoy it, if you have a Smith and Wesson – enjoy that as well.
Optics Planet has a good selection of red dot sites. One in particular that I have seen mounted on an AR is a TASCO that is currently being offered for $129.00. Dependig on how your factory sites are set up, you will need the burris extra high rings to go with it. Appears to be a nice set up for about $150.00. Another site I would reccomend is RRAGES.com. He has some awesome accessories for the MP 15 22, the Colt ar15 22lr, as well as the GSG configurations. Prices are great and he offers 100% satisfaction money back gurantee including the shipping costs!
I finally had a chance to test out the replacement colt. To my disappointed I have all the same issues. I also had a chance to test out the M&P 15-22. Aside from the colt problems I’ve had I really like the M&P 15-22 better. The M&P on numerous occasions has gone into burst mode, starts spitting out bullets like a full auto 3round burst. Not sure what that is all about. I plan to send the colt in to UmarexUSA at least once. If that doesn’t fix it, It will be sold at a loss.
I’ve been ready all the issues with the Colt M4, which I’m having the same problems. My issues are like everyone else, ammo just keep jamming. But I’ve determined a couple of ideas that might help. If you push on the magazine assist loading button upwards as you fire the rifle (which you are helping the spring), this seems to eliminate failures. Once the button gets past the magazine input it will jam because one can’t press to assist the spring at this point. So, I’m trying to find a higher “K” constant spring to place the original spring in the magazine and run some more test.
Another issue is that running ammo with higher velocities > 1250 fts seem to work much better. Umarex recommends RWS 40grs which I believe the manufactures stated velocity is 1460 fps. I found that I have less failures with higher velocity ammo.
Other issue, which I have not yet placed my hand around, is the shell doesn’t hold probably as the fired case is being ejected as a new case is inserted. My guess at this time is where the end of the shell base sites on the bolt needs to be milled out deeper or the shell holder is not quite long enough. I need to get a spare bold from Umarex an make some modifications. Why do I believe this, if one looks at where the shell eject pin is located, you will notice the shell will dis-log before this pin is hit to eject the spent shell.
When It comes to cleaning, the Engineers should go back to the drawing board.
Guys I had the same problem with my ops. It would stove pipe about every other round. I called umarex and they told me to send it in I sent it to them on a wednesday and they got it back to me on tuesday super servive also gave me a 30 round mag for my trouble. They replaced the extractor and adj the ejector and now it never misses a beat. I have fired two full mags as fast as i can pull the trigger I have probably fired close to thousand rounds since and it never misses a lick keeps on going. So guys they can make the little JEWEL work like magic. I also have the Colt carbine and after it broke inn it is very reliable and never misses a lick just like it is made to do. I use the Federal 550 value pack ammo and have no problems with this cheap ammo. So guys if you have problems don’t give up The guys at umarex can fix the little jewles. I simply love to shoot these rifles they are a BLAST to shoot but is very sad that we haft to send a NEW firearm back to get to work wright.
Kenny, Have you tried adjusting the tension on the firing pin spring. It should be turned in 9 full turns with all ammo. Also, the type of ammo is definately a contributing factor. Use cheap ammo and you will get the failure to feed, failure to fire, failute to eject, etc. In regards to the carrier not picking up the shell and pushing it into the firing chamber. you need to make sure the nose of the shell is pointed slightly up and that the back of the case is situated as far up in the magizne as possible.
Did turn the spring in 9 turns, but still had jamming issues. Also, tried difference magazines with the same out come. Another observation we noticed was the gun likes to be run dry, not like a AR-15 which need to be oiled all the time.
I have completely disassembled the gun and gave it a good cleaning. This will determine if soot build-up might causing some of the issues. I’m not convinced this is the issue. Thanks.
Sorry to hear that everything you have tried in not working. I have noticed that they do shot dry even after oiling. That surprised me as well. I hope you get thing straightend out and get it firing correctly.
kenny i had the same trouble as you at first and was frustrated also. i loosened the flash supresser (that was too tight from the factory) turned 9 turns on the adjustment screw and only tightend the supresser a very little bit.now i shoot almost all ammo even the ones that did not work in the begining
george
George now that’s an idea. I will try loosing the flash suppressor. I already have it turned down 9 turns starting point was with the allen screw flush with the aluminum bolt carriage.
I had a FTF problem using CCI Mini Mag, about 15::300 rounds. But this only happens when loading a fresh mag and closing the bolt. I read the post above and turned the recoil spring all the way in. Tried to cycle with the Mini Mags and seems to feed well now. Will test shoot this week end.
kenny, umarex recomends on there video that you loosen up the flash supperssor before adjusting the allen set screw 9 turns. i dont know if it means anything but when i first adjusted my set screw i did not loosen the suppressor and still had the problem untill i did it the second time around as the video shown. then it worked fine. maybe if you dont loosen it, turning the set screw wont set the right way
george
George, tore the rifle complete down. The suppressor only supplies tension on the barrel which hold the bold carriage in place. See no advantage in loosing the suppressor first. What I did find is two issues, one I’m not for sure about regarding the ejector length. The ejector pin looks broken. I have another on the way from Umarex to make a comparison. Next is the extractor which should hold the shell until the ejector pin hits the shell to eject the casing. With the bold out of the rifle, the extractor will not hold the shell. There is about 10 to 15mil of play. So, when the shell is being extracted from the barrel, the case falls off before hitting the ejector causing a jam or some called stove pipe. The ejector relies on moment to eject the case correctly. If the extractor does not hold the case, then ejector pin can’t do hit the shell. I have dialog going with Umarex, but they think it is the pin that holds the magazine in place. I know there has been a lot of issues with the mag falling out. I will email Umarex today and ask about the extractor issue. By the way, both MP15-22 and Ruger 10/22 will hold the shell with the bolt out of the rilfe. There is no play.
I had the same issue and sent one of mine back and it is extraction much better. I do believe the extractor needs some rework, the angle and relief on the extractor is not good, the rounded outer portion rubs in case and keeps hook from fully engaging rim. I may modify myself.
Is there a take down guide somewhere? I heard you can send spring launched parts all over shop if you do not know what you are doing.
Tim
go to link for take down info…CALGUNS.NET
http://www.calguns.net/calgunforum/showthread.php?t=222049
No more FTFeed with mine but still having occassional light strikes, about 1 to 50 rounds fired. Usually fires the 2nd time. Any suggestions? Ammo used are Federal, Winchester, Armscorp. Although I didn’t have any LS with CCI’s.
Other than FTFeed there are no other issues. Still fun to shoot, I can hit a 4″x8″ steel plate at 100 yds all day.
Ray good link:). Does anyone know how to remove the extractor? I thought removing the pin the that hold the firing pin I could remove the cover to get the to the extractor. Well, this was not the case. Couldn’t remove the cover after removing the pin. I believe I’m going to have to send it back to Umarex for evaluation and/or adjustment.
ray that was great, great, that website you listed. really shows how to breakdown the rifle.
the pics are really clear.
thanks
george
hey, im just a kid so bare with me. i dont know to much about rifles and im thinking about getting the colt m4 ops. would you suggest this as my first real rifle? and i noticed the front sight sticks up quite a bit in the pictures. would that get in the way of a scope?
The link info was given to me by Bill Springfield when I went to inquire about how to remove the trigger group so I can send it to him and he can work his magic on it. I never did though, decided to just wait for the match trigger group that Umarex is planning to come out with.
When I clean my rifle now I just pull out the bolt/barrel group and spray brake cleaner to clean it. And drop of oil on everything. Much easier to do.
Gabriel, I would not recommend this rifle. If you look through this bog you will see the many issues people have had including myself. I gave my son a ruger 10/22 and he loves it. In fact Ruger just came out with the
SR-556 and I wish I had bought this insead of my Colt M4 22lr.
Check it out @: http://www.ruger-firearms.com/products/sr556/index.html
Good luck…
Gabriel,
My bust it’s the SR-22 @: http://ruger.com/products/sr22/index.html?r=y
Good Luck!
ray, thats good to know, i will do the same only i use auto carbruator spray. only thing you have to be very carefull on some plastics
george
I agree with Machine Gun Bob. I worked with ISO900 standards for a defense contractor. A vague reference to 9 twists of the wrist would not be acceptable. Written procedures would have stated (turn X degrees from zero to x degrees stated 9 times).
Hey Bob did you ever work with the old time QC gang at the Chevrolet Cadillac street garage?
Gunner25
ray, be very very carefull , i was going to clean the rifle like you only take out the barrel and the latch handle with the bolt group. but when i pulled on the latch handle ,witch was a little stuck a little spring and pin came out too. i had to take the whole receiver apart to put it back. it works the mag and holds the bolt open. what a job, i think its the smallest spring on the whole rifle
george
Does anyone know how to remove the extractor from the bolt??????
Thanks for the warning George, I wonder how that pin and spring popped out without disassembling the bolt section? Is that the one that sits under the barrel chamber? You’re lucky you didn’t loose that part. Happened to me when I was working on my AR15, the buffer retaining spring flew out and never found it. Good thing the shops here stocks them.
I noticed also when I pulled mine out, the four nuts holding the assembly was a little loose so I tighten them up maybe put threadlock next time. One more thing to check…
Another issue I have is the wobbly stock. Wanted to replace it with a Magpul. I emailed someone from the other forum where he replaced his with a Magpul CTR Mil-spec and he said that there was still movement. Guess I just have to live with it.
yes ray thats the spring under the barrel chamber. just keep the bolt window up faceing you while its on the bench as you pull out the chargeing handle to take out the barrel. if you have the spring window showing the bolt face down the little pin that holds the spring under the barrel will fall out and than the spring will unseat. also does brake cleaner damage some plastics ????
george
George, I’m using Prestone break cleaner (non-chlorinated), not sure if it will harm plastic but I’m not taking any chances. Only using it to clean metal parts like the bolt assembly, works pretty well.
I had just purchased a Colt M4 ops 22 just as a practice weapon. I have a Colt 6520 and I have to call a spade a spade. Right out of the box it was faulty. The bolt carrier spring was not strong enough to push the ammo into the chamber all the way. I tried several different brands of ammo and all with the same results. I contacted the dealer and he refunded me my money. Not reccomended !!
ok ray, i use carbrator cleaner i test the plastic first with a small q tip
take care george
I got real brave and completely disassembled per the previous web site.
If you are careful and do not let barrel slide to rear until you are ready to split the carrier the little spring will behave. As for putting it back together I found if you leave the pin out for the bolt hold open lever you take most of the pressure off that D— little spring. Once the barrel is back in place (you need a lot of patience to hold every thing steady) you can slide the pin for hold open in slide bolt forward while holding barrel and then slide the other half of carrier on. After a few tries it is a piece of cake (almost).
I did see the problem with the extractor. They used a key cutter to make relief for extractor, it needs more relief near end of chamber. Next time I will have a 3 mm end mill and mill this back straight for 2 mm or so and the extractor can then grab the rim better. I believe the only reason it works at all is that after ignition the casing is pushed back with bolt and if you are lucky the extractor catches the rim.
The tear down is not that bad, I only used mineral sprits and compressed air to clean. The graphite goop they used at factory comes off easily with a soft brush. I used Rig grease on all sliding surfaces hope this does not gum up as bad. Have a group of scouts comming to range tomorrow so they should give the carbine and rifle a good work out.
Tim in NC
ray, i made a mistake when you pull the bolt receiver and barrel out of the plastic barrel shroud the spring window must be down ,not up like i said the last time
george
Guys I have a fix for the wobbly stock or loose stock. Take three strips of black electrial tape just shorter than the length of the stock and put them in the stock one at 1200 oclock and one at 5 oclock and the last one at 7 oclock the tape takes the slop out of the loose fiting stock and I find that it fixed mine up great. The black tape is unoticable and works great.
Folow up to disassembly and full cleaning. I had a chance to let the scouts shoot both the carbine and rifle today and I was amazed in the difference. Both had no issues at all shooting Winchester black box bulk ammo. The ejections were clean and shot 10 ft out from rifle. Other than a good cleaning especially the bolt, I did slightly file the extractor relief not very much though. I did do one thing on reassembly, I tightened the flash suppressor with the supplied wrench and then backed it off and re-tightened to only “hand tight”.
Do not know what made the biggest improvemment but it is a different gun now. Will do some more range testing when weather improves later this week. For now I am a happy camper!
I do have 2 GSG’s , AK and MP5, a S&W AR22, and the new Sig 522 and I believe the Sig is the best of the lot except for the miserable mag. It loads and feeds OK it is just a pain to load.
Tim in NC
@George- got it, thanks. Good looking out. I’ll make sure to do that next time I clean it. Come to think of it I could have lose that spring too the last time I cleaned it.
@Sherman- thanks for the info also, works good! Much better now. Save me from buying that CTR.
Tim O in NC, this might be a tough question since there are no pics to post, but how did you file the extractor relief ?
ray, i had a loose stock too a while back,all i did was open the end plate and thigened it up inside with the long alen wrench that is used for the set adjustment screw

As for the ejector relief I used a small square file, I did more polishing and scraping verses actual filling. I looked at some of older Remington 22’s, 513, 541 etc, for guidance. I filed, scrapped and polished this area as much as I thought possible.
I realized that there is a big difference in semi auto with blow back and bolt action 22 rim fire. The bolt stays forward with the bolt action so you can steal a little extra relief with a rim fire bolt action. On the bolt action 22’s they actually cut into chamber a little with this relief and relay on the bolt for support.
The blow back semi auto needs more support around the area due to blowing back when fired. This is the reason these semi auto’s get so much dirtier than the bolt actions.
Hope this makes some sense, I truly believe the through cleaning did more good than any filling and polishing I did.

I have been interested in purchasing a Walther Colt m4 carbine .22lr for some time. I was wondering if this firearm would take an upper of a higher caliber and also if $700 would be a reasonable price?
Allow me to answer your question: No you cannot add an upper or lower or any other interchangable part from other AR configurations other than external mounting accessories such as stalks, scopes, lasers, etc. Why? Because the Colt M4 is a dedicated .22 that was created to only be a .22
Is $700 dollars a reasonable price? It may be if you are lucky enough to get a trouble free Colt M4 22.lr. I think most people would tell you to either purchase a 5.56 / .223 and buy a conversion kit for it or look into getting the Smith ans Wesson version M&P .22 as it will take just about any .22lr ammo you want to feed it where as the Colt M4 ops likes the high grade CCI, winchester, and federal ammo. If you want the most accurate gun then get the M4 ops and feed it CCI mini mags if you can find them.
Places like Gander Mt. Sell the Colt OPS for $699.99. I find them for around $530.00 at local gun stores in MN. I had two Colt M4 .22LR and both failed to perform at any exceptable level. I ended up trading it even up for Smith&Wesson M&P15-22 ($430.00). I now have two M&P 22.lr’s and have been very happy with it. With my experience with the Colt M4 .22lr I have a hard time recommeding it, too fustrating and as a FFL holder, I will not stock or resell them. Hope that helps. I have some very nice pictures of all the problems/jammings with the colt. I’d be happy to pass them on to you. I will say URAMEX is a good company and appears to be servicing these promptly when sent in. I’m awaiting DPMS to rebuild its .22LR life of rifles. DPMS all the way.
Vastar where are you in Minnesota? I am in Bemidji and just sent my trigger assembly to Bill Springfield for rework. Other wise i have had no problems with mine I shoot nothing but Federal 510 in it. Lot of fun to shoot. I allways sad I would Never have a AR type. But this gave me the bug so I just bought a Rock River Lower no sure if i will go with a 6.5mm,6.8mm or 450 bushmaster upper
Gerald A:
I am in Belle Plaine. Glad to hear some are having luck with the Colt OPs. I tried Federal SpitFire, Federal 550, Winschester, you name it. All failed at the same rate. I’ll have to say when it did fire correctly it was very accurate. I deal with DPMS and Bushmaster and have heard good things about Rock River and Stag ARMS.
Hi-all,
As a veteran of Iraq who carried an M-4 in combat. I wanted a fun plinking gun that was familiar. I don’t like the S&W MP15 plastic design and again I wanted the basic M-4, I carried in Ramadi. I just bought the standard the M4 for $470 and I am going to try it out tomorrow. I watched the armorer video at Umarex on how to field dress it and turned the spring adjustment screw 9 (180 dg) turns to prevent potential FTFs. I am going to use Federal ammo and let everyone know how it fires at the range tomorrow.
I fired my M4 22 lr at the range today and I was happy with it. I did have some problems though. The rifle shoots low and to the left at first. I adjusted windage and fixed the issue, but the rifle is still shooting low (1.5 inches) after adjusting the front site post. I had a good group, but zeroing is another story. Do I need to get a longer front site post? Will Umarex replace it if I call in? Anyway, loading the rifle I did have some issues with getting the first round failure to feed, I just pushed the 1st round towards the front of the mag when loading and all the problems went away. Once the first round is in it did not jam. It is not like a real M4 because the dust cover, bolt catch, and forward assist are not functional, but for plinking -the rifle is fun. I ended up shooting around 250 rounds and had a good time. For someone that wants to shoot an M4 – I would say it is accurate like the M4 I shot in the army because I had jams / zeroing issues with M4 / M16s at 25 meters during qualification. I could qualify with this weapon if I had too. Good time / fun weapon. Could someone please answer the front site post question?
Thanks,
Hello all,
Took awhile to get thru all your comnments, experiences.
I picked up a standard M4 Colt/Umerax and have had excellent results with my rifle.
Extremely accurate at 25 yards from sand bags with stock iron sights. No issues with FTF’S or adjustment of front sight. Ammo tried to date has been five different value pak/brick’s of both Federal and Winchester, not a singgle problem.
Gawd I hope Murphy (Murphy’s Law) doesn’t read my comments! ;>)
I also have a S&W M&P 15/22 and have also had excellent experiences thus far as noted above with the Colt. One hole ten round groups using a Bushnell Trophy Red dot scope at 25 yards from a sand bag rest.
Bolth of these firearms are very different yet similar. Love them both and would reccomend them highly based on my experiences.
I put an after market spring kit for a standard AR in the S&W and improved the trigger significantly. Cost, $10.00. I also mounted Hogue grips on each firearm. The S&W was a snap to install and the Colt required about 15 min’s of modificaton work to the Hogue grip to get it on.
My next step on the S&W is to take a Dremmel tool with a buffing wheel and smooth out the contact surfaces on the S&W trigger group. I’ll then put my Lyman Trigger Pull Gauge on it to check how many lbs my trigger pull is. The best test will be at the range for functionality and that all important “feeeeeeeel”.
After the holiday’s I’m going to see what I can do about installing a free float front hand guard while removing the front sight on the Colt as I would like to install a sight on it. I’m hoping a Hogue forend will be able to fit with little or no modification. Anyone try this yet?

If you will give umarex a call they will send you a taller front sight.
They are very good to work with and they have super fast service.
Thanks for serving guy. I know it is bad over there.

@GEOJR – what do you use with the buffing pad to polish/smooth out the surfaces?
Ray,
It’s a four block buffing kit that came from Sears for use on a regular sized grinder with a buffing wheel attached to the grinder. The colors are White, Black, Brown and deep Red. Each of the colors has a certain abrasive rating. Unfortunately the top of the box they came in has long since vanished as I must have purchased the kit 25+ years ago. With the box top went the part number and grit rating for each block. I used the deep red on the trigger parts as it is a medium abrasive. One of my sons might have a set of these abrasives, I’ll check with them today or you might even find it on the Sears tool web site as I’ve seen them at the local Sears stores over the years. It will only smoooooth out your trigger so you don’t feel that eternal gritty drag. Still a long pull, but hey it’s a rimfire and you adjust to it quickly. Also, the more you shoot the gun after the polishing the better it gets. Usually around 500 rounds which in my case doesn’t take long with a rimfire! :>)
The spring kit is a JP Enterprises, Inc. kit #JPS3.5 which includes a Reduced Power AR Hammer/Trigger and Dis-connector spring. This took my trigger pull on the S&W M&P 15/22 down to less than 4lbs and made a dramatic difference. We’ve installed about ten of these sets in various AR .223’s with excellent results thus far. You can find the spring kits a various web sites for less than $10.00.
We’ve always gently polished the hammer and trigger so as not to diminish the integrity of the metallurgy of the parts themselves.
Hope this helps.

Geojr, thanks! I’ll check Sear’s today.
Ray,
I polished the trigger contact points and then lubed them yesterday. Spent around 20 minutes polishing, average time I’ve spent thus far.
Took the rifle to the range today.
The improvement was significant and immediate. It just kept getting better and better. Put 200 rounds thru gun and couldn’t ask for a better trigger (with the spring kit also installed).
geo
Since I posted my through cleaning I have run a lot of rounds through the carbine and rifle. No issues at all with feeding or FTF. I can not believe the difference not the same rifles. I am using bulk Winchester, Dick’s Federal 714 target, bulk Federal, and CCI standard. Not sure how long it will take to load up with crud but the light weight Rig grease seems to be a big help over the gritty grease that comes from factory. The only other mod was to polish up the extractor recess while I had it apart. I did spend some time cleaning the bolt and using a light oil to soak down into bolt. I also lubed the recoil spring with Rig grease.
All in all they are both shooting very well with the above ammo.

Hello, I have read all the post on this site and it appears a lot of folks who post, just had there first experience with a 22 rimfire. I have been shooting them for 40 years or so and found the best way to make them reliable is to clean them often especially the chamber. My first gun was a Remington single model 4 and after about 100 shots I had to use either a pliers or straighten clothes hanger to push the empy round out and once i cleaned the chamber the rounds went in and out slick as snot. My second and third experience were semi auto rifles Win, Rem,Marlin and again once they were dirty they were jamomatics, until the chamber and ejector were cleaned. I believe the same holds for almost all autos exspecially 22 rimfires . The dirtier the chamber gets the harder the case pulls out and on a 22 rimfire the stamped case is slighty tapered and rounded were the ejector pulls the case out so the dirtier the gun gets the harder the case is to pull so the ejector slips off before it is completely cycled, not like a c/f .223 round that has a flat machined rim for the ejector to pull from. I do have a Colt 22lr ops m-4 and had no problems with it, but I always clean it after a couple hundred rounds. I read some post that the Remington ammo did not shoot so like everyone else (curiosity kills the cat) I had to try them since I had a box around. I shot around 70 rounds of Remington Thunderbolts and about 70 rounds of Winchester bulk with no misfires from each round. To my surprise I could pick out which round was the Reminton from the Winchester before I even looked at the maker marking on the back of the case because the Reminton case was blackend by burnt powder leaking by. I mic’ed the Reminton case and the Winchester case and the Remington case was .001 under the Winchester .024 Rem and .025 Win which aloud gas and burnt powder to escape pass the case which in return dirtied my rifle much faster. “I would not use anymore Reminton ammo in my rifle”. I with others was not real pleased that funtional parts were fake and parts were not interchangeable to the AR-15 like S&W’s which modeled there internals like a .223 to .22 conversion, but I must say I really do not have any complaints about the gun either it seems to fire great and the accuracy is fantastic. Besides I read reviews on the S&W and GSG 5 and they all have complaints about cycling. Moral of this story is keep your gun cleaned and it will shoot well for you as for the poor soles that had several problems and sent the gun several times to get it fixed I would demand my money back or demand a new gun, because like most gun makers a lemon poop up but is not common including the ruger 10/22 which I really like. I bought my Colt M-4 and 1,000 rounds of 22lr for just over $500.00 and a 1,000 rounds of .223 are $500.00 “ALONE” if not more , so I bought the ammo and got the gun “free” so to speak. Now all you anti Colt’ers cut me some slack on the free gun part I know I’ll get some slack from that , but I have many AR’s in different makes and calibers and love them all. Take care and have fun thats the name of the game also join the NRA keep or rights to own our weapons
All,
First and foremost I absolutely agree without reservation ALL of Jim’s comments above. Rimfire’s are persnickety lil’ buggers about what ammo they will and won’t shoot and are notorious for needing to be kept clean in order to function properly. I never, ever put a brush down the bore of a rimfire now that they have the ” Bore Snake” on the market!!
Hat’s off to Jim’s comments!!!!
Some information regarding S&W’s AR rimfire.
I’m starting to accessorize mine like most gun enthusiasts do.
What I’ve discovered so far is the entire trigger assembly is interchangeable with almost all AR .223 parts.
The trigger pins are exactly the same, but, the palomar action is thicker than a standard .223 receiver and therefore the stock pins don’t sit flush with the outside surface. This is only an issue is you want to dress it up with a pin kit as I did. You’ll have to fill in the external pin plate slots on for each pin to make it a tight fit.
Amdi bolt releases won’t work as they are significantly different.
After market bolt handle release can be made to work. You’ll have to modify the locking contact point that locks onto the receiver, but it can be modified.
Ambi safety, no problem.
Rail covers, no problem.
After market front sling pica-tiny mounted units, not a problem.
I’m also going to see about modifying my Colt with a free float hand guard and replacing or removing part of the front sight so I can mount an optic of some kind.
More to come.

Thank you geojr !
I bought my Colt M4 a few months ago and have run about 1000 rds thru it thus far…and it shoots great…after reading this whole sites comments, I guess i should feel lucky. Only a few snags (short site post) and no feed issues or failure to fires… I shoot the standard cci stuff and it shoots great. Now I want to put all the “toys” on it. The Ops version wasn’t available at the time of purchase. Has anyone put a rail on a standard m4…not a two piece but a free floating one…umarex has one. Is it easy to install or am I taking it to the gunsmith?
Thanks,
Burkedogg
I bought my Colt M4 ops .22lr a few months ago. My wife made me wait 3 months for Christmas to get my hands on it. During this 3 month period I have read every blog post there has been. I think about 85% of everyone has problems with this gun. Now I guess its my turn. The first thing I did was properly field strip, clean it, and adjust for the CCI High Velocity ammo that I was going to put through it. I thought I was golden, boy was I wrong. Right off the bat after a few shots, “Fail to feed” and then again after a shot or 2 and then again. out of 40 shots I had 15 fail to feeds. Not quite stove piped but they did not feed completely snug so that the firing pin could properly strike. I tested with a 30 round mag and a 10 round mag and same thing. I also tested with 40 grain and 36 grain CCI HV amo. The gun seemed to do better with the 36 grain ammo which was had a higher FPS rating. When I first shot the gun I was using 25 year old CCI mini mags, 40 grain. I thought that was the problem so then I broke out the new stuff and same deal. I am going to field strip the gun and back down the velocity bolt a half turn or so to see if that works any better. Why should I even need to do that? My Ruger 10/22 has not once had a fail to feed in 5,000 rounds. Umarex should have made a recall of all rifles and then fixed the problem before making more but nooo. They just keep making these guns with the same specs so that the problem has never resolved. yeah I hear their customer service is good but why should 85% of everyone need to send the rifle back? This is a bunch of BULL. Merry Christmas to me. Thanks Colt / Umarex. P.S Burkedogg, you should be thanking your lucky stars for getting one that works. I feel like spitting right now.
The solution for my M4 was simple, “DON’T USE REMINGTON AMMO” . They’re too chubby or something, they won’t chamber all the way, they won’t always seat, about 80% of the time. Federal, CCI, and Winchester work flawlessly.
IF YOU WANT A GOOD AR ( M-4 Clone) GO BUY A REAL ONE (BUSHMASTER , Colt , Olympic , Stag , ETC. ) If you want a good .22 Then Go buy a Ruger 10/22 or even a Mossberg Plinkster (Plinksters are cheap as hell but pretty good little rifles). In my honest opinion keep with what the weapon was originally intended for and don’t fall for something that has been thrown together to look like something else just so a manufacturer with a big name can make more money. 10/22’s are simple little rifles and are very good for their intended purpose ( TO BE A .22) AR’s Are Also very good ( TO BE AN AR or m-4/m16 clone of their military likeness) YOU DON’T BREED PIT BULLS WITH CHIHUAHUA’s , Right??? SO why breed a military rifle with a pea shooter!
Oh , and please don’t give me ” WELL I JUST WANT TO PRACTICE WITH AN AR WITH CHEAP AMMO CRAP”. AN AR, M-4, M-16 is nothing like a .22 When you pull the trigger ! It comes down to recoil and muzzle rise! Follow up shots are real easy and forgiving with a .22, not so much with an m-4 ! recoil isn’t much of a factor but it is still a little more! If you want to practice with an AR 5.56 or .223 THEN GET ONE SPEND THE MONEY, GET GOOD WITH IT, AND PRACTICE , PRACTICE , PRACTICE ! .22 ’s are for shooting beer cans , cat’s , and squirrels. THERE…. I HAVE SAID MY PIECE. MERRY CHRISTMAS AND HAPPY NEW YEAR. I HOPE I HAVE HELPED SOME OF YOU WITH YOUR DELIMA’S !
I BOUGHT MY COLT 3 MONTHS AGO AND WHEN I FIRST FIRED IT I WAS PISSED EVERY 2ND BULLET JAMMED BUT THERE IS A WAY TO FIX IT YOURSELF. FIRST TAKE THE 2 PINS OUT HOLDING THE UPPER AND LOWER RECIEVER TOGETHER DONT FORGET TO LOOSEN THE FLASH. NEXT TAKE THE FLASH ALL THE WAY OFF THEN GRAB THE CHARGING HANDLE AND PULL. BE CAREFUL BECAUSE EVERYTHING INCLUDING THE BARREL COMES OUT. TAKE THE VELOCITY SCREW OUT AND THE SPRING THEN TAKE THE 5 SCREWS HOLDING THE SLIDE HOUSING TOGETHER OFF AND PULL IT APART. NEXT TAKE THE BARREL OUT. BE CAREFUL OF THE SLIDE CATCH SPRING. NOW IF YOURS IS LIKE MINE THE BULLET GUIDE IS SET TOO LOW TO THE BARREL. TAKE A 6 INCH ROUND FILE AND FILE DOWN THE EDGE. BE CAREFUL NOT TO SCRATCH UP THE INSIDE OF THE BARREL. NOW WHEN YOU PUT IT BACK TOGETHER PUT THE EJECTOR ON AND SLIDE THE SLIDE OVER IT TO HOLD IT IN PLACE. THEN TAKE THE PIN HOLDING THE SLIDE CATCH IN OUT SLIDE THE SPRING IN PLACE PUT THE BARREL IN PLACE HOLD IT TOGETHER AND REPLACE THE PIN IN THE CATCH. PUT EVERYTHING ELSE BACK TOGETHER AND FIRE AWAY. THERE IS AN EXPLODED VIEW OF YOUR GUN IN THE MANUAL GOOD LUCK
Just purchased an m-4 carbine (.22). I am a tac instructor ho wanted more trigger time with a weapon system that was fairly identical to my existing m-4. While it is not an AR/ M-4, it will take all of my add on gear, and the ergenomics is nice. I Was extremely pissed with all of the issues initially, but seem to have much of it all worked out now. Umerex’s people were excellent to deal with over the phone and pointed me in the right direction with regard to ammo, etc. Several observations thus far:
I love the ease with which you can load up the magazines…very easy to do and easy on your fingers after a full day of blasting away! Beats the hell out of getting “M-1 Thumb” with my other .22’s…..
1) had serious issues with many types of ammo and was ready to stomp my new rifle…IE; wolf, remington, winchester, etc.. but then HAD FLAWLESS RESULTS WITH CCI MINI MAG 40 & 36 Grain.
2) The cleaning issue sucks, however, I just use GUN SCRUBBER and hose it out thoroughly while at the range, then oil as needed.
3) Some feed problems may be caused by grabbing mag well with support hand while shooting (something I like to do), as your hand may interfere with the spring tension button on side of magazine.
4) Rifle was extremely accurate, but sighting it in was a bit of a nightmare. I may well throw my aimpoint on it or another red dot site, possibly try out a lazer…
5) the non functioning dust guard issue sucks, but is likely a matter of there not being enough energy to both knock the dust guard open and cycle the round properly at the same time, so it is better that it does not work. If it worked the rifle likely would not!
6) I have worries that loosening the flash supressor in order to break down the weapon, may throw off my zero, as it will be “hand tightened” to different torque each time I do it in the field. Have not verified this though.
7) I was told by Umarex that the rifles come set for Euro ammunition, thus the need for tightening the bolt spring down nine or more turns from the flush position.
Ill stick with the new rifle for now and hopefully get some cheap, but effective training in with a weapon system that I am used to shouldering.
Again; BUY CCI Mini-Mag High Velocity AMMO!!!!!and Gun Scrubber!!!!
Hope this helps folks a bit-
AF-
rilly nice wepon it cock fully but thats what the fourwerd asist is four i got it four my 12 b day
i forgot to put didnt
great gun i cannot say how much that this is everything that i would have expected in a gun
My friend and I bought Colt 22 lr M4’s at the Gunshow thinking they would be a fun plinker without burning 40 cents per shot like our .223 models. We bouhgt them from the same dealer and tried both bulk ammo and some high velocity CCI. The results were similiar. His gun would not seat the mag correctly and even showed deep gouges in many rounds as they failed to seat properly. If we held the mag tightly into the M4, it helped, but not 100%. This gun needs smithing. My M4 had less of a problem, and even got through one mag without by holding it up into the M4 tightly, but this is not a proper discipline. It may have a bit of a break in issue, but this is just not right. It also did drop the mag a couple of times and jamed every fourth or so round for another 4 mags.
We are going to send them back for service. I have a couple of GSG 22lr carbines that almost never fail, maybe one out of every 200 rounds. I don’t expect them to be perfect, but these are really frustrating. I will let you know when they come back and how hard it was to get them repaired.
I have had my Colt/Walther/Umarex M4 22lr carbine for about a week. Today, I took it to an indoor range with my son, and we ran 100 rounds through it. We had several failure to fires (perhaps one to two per magazine on average). While this was frustrating, I think some of it may be a result of the way I fed the magazine. In general, I like the feel of the rifle and the way it fires. The resolution was easy when it failed to fire, pull back the bolt and feed another round after ejecting the one that didn’t fire. (Reloading the ones that failed to fire invariably led to their firing.)
Our target in the range was 25 meters away and was constantly swinging left and right (due to rolling it out on ropes after placing the target, bringing it back to check our zero adjustments, etc.).
We also had one stove pipe. We were shooting Winchester High Velocity ammo but did not do the 9 turns as suggested by Umarex and people here.
I noticed that our rifle was pretty dirty when I first took it out of the box. There were metal chips and dust from manufacturing and shipping. I am wondering if this, too, may have contributed to the misfires?
That said, I am impressed with the construction and “feel” of the weapon. In some ways, it was like becoming reacquainted with an old “friend” I had in the army back in the late 60s and early 70s. It was a pleasure to squeeze the trigger, feel a bit more of a kick than I expected and hear a louder report than I expected from a .22.
While some things don’t work the way they do on a real M-16, I knew I was buying a replica when I laid out the money for it. I am not at all unhappy about paying $595 for this rifle, feel it was money well spent, and it has given me a new respect for .22s.
I look forward to ironing out the bugs in this rifle and having many hours of fun with my son and wife (who says she is interested in shooting, too).
I hadn’t picked up a rifle like this since I got home from Vietnam, and I was surprised how comfortable this one felt in my hands. I own an SKS, and I didn’t enjoy that at all. Some of the cosmetic differences between this new rifle and a real M-16 may have been a bit disappointing because the rifle wasn’t “exactly” like the one I had, but the fact that my 14-year-old son and I had fun together with something I knew a bit about far outweighed any minor disappointments.
Watching my son shoot for the first time in his life, learning about weapons, firearms safety, shouldering the rifle and pointing it down range, and then seeing the expression on his face when he pulled the trigger for the first time was very rewarding. (There was no drill sergeant there to pound anybody on the head with a range paddle. It doesn’t get any better than that.)
Thanks to Colt, Walther, and Umarex for producing such a fun rifle. I intend to keep this and use it with my son for quite a while. Who knows, maybe I’ll get the real deal when finances permit?

I bought one of the M4’s last fall and have had pretty good luck with it, a couple of missfires but nothing major.
I did have the mag’s fall out. On close examination I noticed that the slot on the magazine body for the mag lock was rounded at the corners and the lock was not entering the slot. A little squaring up of the shoulders with the can opener point on my pocket knife and the mag’s lock tight.
Well, here goes. I had put this gun on Lay-away back in Oct. 2009. I wanted an inexpensive 22LR that looked similar to the issue M4 so I could train with it for less than a real AR, (which I already have). On the way to make another lay-away payment with my girl friend. I showed her the Colt and she says “I like this. This feels good”. Coming from a girl who has only shot firearms once. I took note. Well! It became her Christmas present. She loves it!
Now, along the way I’ve been reading all the responses to the Colt M4 and freaking out. Did I buy to early? Should I have waited until they (Walther) fixed all the bugs? I have to say that educating myself with all the information on this thread about ammunition, cleaning, magazine loading, magazine seating, and sighting in has paid off. We shot it today for the first time and my GF loves it! Not one miss feed, stove pipe, or miss fire. I did not get the chance to sight it in today as I just wanted to let her get used to firing her weapon. We also shot the Sig 522, a S&W 422, Glock M27 40cal and my Bushmaster in 5.56. She tried all of these and did great! But she said she loves her Colt M4 the best. Ending comment, I was pleased with the Colt and hope the next time it performs just like it did today. The smile on her face was well worth it.
Good luck to all
well i have been cleaning my colt ar 15 umarex as was in the pics that ray listed the web site ,and have not had 1 ftf any cycleing problems. i also use any ammo except remington. this for a few months
I received the Colt M4 Opps fro christmas and fell in love with it! I have shot the M4 and M16 and love them both dearly and am very farmiliar with feild-stripping and maintaining them. Needless to say I was very eager to go to the range and burn up the ammo the was taking up space in the gun safe. Well the day finally came but to my dissapointment the rifle jammed horribly! On my return home (after only fireing 2 mags) I began reading up on the issues of the rifle. I must say i was deeply releived when I read that almost everyones hated remmington 550 bulk ammo. So on my way to up to S.C. for a ski trip I stopped in the bass pro outside Atlanta to see if they had any cases of CCI or Fedderal amm. To my dismay they didn’t, all they had was Remmington Trundicated tip high-velocity ammo so i picked up a box. As soon as I got back I went back tot he range and had a blast! i made the adjustment for high-velocity ammo and didnt have a single problem(except one round was a dud, it was struck hard but didn’t fire)! As of now that all I use, I deeply recomend this rifle to anyone who wants to buy a good .22 tactical rifle. Not to pick on anyone who bought the M&P 15-22 but why would you pay the same amount of money for a gun made almost compleatly out of plastic? I can use Break Free between cleanings but with the M&P 15-22 you cant due to all the plastic. This is easily the funnest and cheapest(on ammo) rifle iv ever shot. Thank you to all who posted on here, you insight helped me tremendously!
Well, it has been 2 months since I bought my Colt M4 22 LR and since I got it sited, it has been a blast. I have put around 1500 rounds thru it and rapid fire it often. I got it zeroed and it has remained extremely accurate at 100 yds almost as good as my Savage .223. The only thing is I push the first round forward in the magazine when loading and it prevents FTFs. It is a great little rifle and fun to shoot. Not so fun to clean, but very fun to shoot. I recommend watching the Umarex armorer’s video before field stripping and use Federal ammo so you can plink all day. By the way- Remington ammo jams it and my Walther P22.
Hi all.
I’ve had my .22 M4 for over three months now. I love it so much. I haven’t had any problems with it except for adding the RIS forward due to the fact I didn’t have a AR tool. I just took it to my local gunsmith and he added it for less that it would have cost me to buy the tool. As for the ammo, I use CCi mini mag 36 grain. I’ve fired close to 1000 rounds now and haven’t had a single jam or stovepipe issue. But I do clean the rifle after about 300 rounds or so. For the most part it is a great plinker and love the look of a M4. I live in Cali so a regular M4/AR is banned here. So I have the look of one and can shot it for far less than if I had a genuine M4 in another state. I am sorry to those of you that have had bad experiences with yours. Umarex has good customer support so I hope you go to them before you give up on your rifle.
Hello all, I am one of the owners that love this rifle. I have been using it to practice my offhand shooting. As I wrote in my previous post I have a number of AR-15 rifles in 223. After I received the taller front sight from Colt, I have been able to sight the rifle in without raising the front post to high. The next problem was the width of the front post. I am accustomed to the National Match .050″ post. The Colt front sight is close to .100″. I took a chance and chucked the front sight in my electric drill. With the drill laying on its side and locked on high, I used a fine file to see if I could round the sight and reduce the diameter. IT WORKED LIKE A SMALL LATHE. I applied light pressure to the file and took my time not to overheat the sight post. I stopped every so often and checked the diameter until I was down to .050″. I then hit it with a little Sight Black and it works great. For those of you wanting to shoot iron sights, I suggest this modification highly. Our club is starting an indoor AR 22LR match. We have members with Colts, S-W, Ruger, and AR-15 Conversion units wanting to compete. I am convinced my colt will hold its own if I do my job.
Dauhmer-
5.56 and.223 are the same thing. NATO calls it 5.56, civilians call it .223.
Thanks for helping us with our *dilemma*. I think most of us know the difference between 5.56 and .22s. While what you’re saying is true, it’s irrelevant. The point of shooting .22 in an AR or M4 configuration is fun and inexpensive shooting, or between match trigger time at a reasonable price. I can shoot my M4 .223 one handed, so recoil is not the issue. It is with my 7.62 NATO rifles and 30.06, but 5.56? Nah. My buddy’s girlfriend shot my Ruger Ranch Rifle in folding stocks so often I finally made her buy her own ammo.
It’s not about breeding bulldogs to Chihuahuas. If it was the military wouldn’t use a laser system to train. It beeps instead of shooting out blood, and people don’t have to fall to the ground screaming. Does that make it a wannabe system? No, it makes it an inexpensive way to train, much as the folks shooting M4s in .22 shoot and train in preparation for match shoots, etc. with 5.56 and 7.62 autoloading rifles. It’s all about pulling the trigger. If you’re shooting BCM (Bureau of Civilian Marksmanship) high power matches, or combat competition, you want all the range time you can get. Some good shooters show up. Plus, if you register and shoot BCM matches, you can qualify for things like the M1 Garand sales, etc. You have to shoot to qualify.
Be safe, firearms and drugs and alcohol don’t mix.
Keep it downrange and hittin’ MOA,

Chris MC –
Great post, good info. Many matches won’t allow anything but iron sights, so info like this is always good. The important part, which you mentioned, is light pressure. Otherwise it will overheat, which takes the temper out, and it’s easy to take too much off. Miking it periodically is a very good practice. When I load match ammo I mike everything, and am very careful with powder charging, since the goal is to hit dead center. I also load in a humidity and temperature controlled room.
Speaking of matches, does anyone here shoot am M1 Garand in matches? If you are making your own 2 round clips for trial shots, I can send you a few sites that manufacture them, as well as 8 round clips. I know this is a site for .22 ARs, M4s, etc., but there seem to be a lot of match shooter/gun club folks here, and there’s bound to be a few that love and shoot Garands as much as I do. I know that mentioning this is off thread, sorry, I just wanted to make a quick mention of it for the match/gun club shooters.
does anyone know if Umarex/Walther has “re-tooled” the assembly line to address the customers problems with the Colt m4? Short notice, but from what I have read the Colt will have a short life if they do not move on customer input expeditiously.
hi does anyone can help with the m4 blueprints? i dont know where to find them if its posible, i want them for a 3d project im on, if anyone can help it would be great thanks
