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.

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?
