Remington ACR

picture-7-5-tm-1-tm.jpg

The specifications of the Remington ACR (Adaptive Combat Rifle) have finally been published. Bushmaster and Magpul are both still very much involved in the development of the rifle although I can see very little that has changed since the original Magpul Masada was unveiled.

The ACR is made up of an aluminum upper receiver and lower polymer receiver.

Picture 18-15

The lower receiver resembles the AR-15 and SCAR lower receivers. Like the polymer AR-15 lower receivers made by Calvary Arms, the ACR’s pistol grip is part of the mould and cannot be removed. The trigger group has a two stage trigger that has a pull weight of 6.25 lbs. The trigger group parts are compatible with the AR-15 / M16. Modes of operation are semi-automatic or fully automatic. All the controls are all ambidextrous.

The operating system was inspired by the AR-18. It uses a short stroke piston system – meaning the piston slams into the bolt carrier knocking is back and cycling the action. The AR-18 bolt carrier design has been improved, at least in my opinion, although it would be more costly to manufacture than the AR-18. The AR-18 has twin guide rods and twin recoil springs, see the photo below. The ACR has a recoil spring that inserts into the bolt carrier and is guided by steel rails that are attached to the receiver.

The bolt is in the AR-15 style with 8 lugs, one of which is an extractor. The bolt can be easily swapped out and a 6.8 mm SPC or 6.5mm Grendel bolt swapped in.

Picture 23-7

Picture 24-8
Steel guide rails indicated by arrow.

The rate of fire is 650-700 RPM. This is slightly higher than the SCAR which features a larger/heavier bolt carrier.

The side mounted charging handle does not reciprocate, unlike the SCAR, but can engage the bolt carrier and used as a forward assist.

Barrels offered will 10.5”, 14.5”, 16.5” and 18” in length and can be changed by the operator without tools. Magpul originally touted compatibility with standard M16 barrels, although Remington does not mention this on their website.

Two stocks will be offered: a foldable / adjustable stock and a fixed stock.

The 14.5″ carbine version of the ACR weights 7 lbs (unloaded)

    What about a 16 inch barrel to be legal with out staking the flash suppressor on the 14.5 inch barrel?

  • Eddy A

    i want this
    so
    friggin
    bad.

  • Phil

    I seriously think that the only way I’d buy this now is if they have the polymer hand guard.

  • jdun1911

    The single recoil spring on ar18 action has a very bad track record. So it would be interesting to see if it actually work with a high rounds count.

    They probably need to replace the 6.25lbs trigger pull with something heavier. Unless it is intended for snipers the US military do not like light trigger pull weight.

    The two stage trigger need to go I think. It doesn’t have good reputation for high rounds count.

  • Danny

    What’s that sniper rifle in the 8th photos do ya see any chance this gettin in hands of US Millitary, will it be offered to export to other countries, i heard India placin a contract for 300000 ARs 4 COIN Troops

  • Gutao

    why did the charging handle design changed so much during the evolution of the gun?first it was on the back,then near the end of the hand guard(and it was on both sides),and now,on the other side of the gun…

  • jdun1911

    IIRC but don’t quote me on it, the M16/M4 trigger pull is around 9.5 or 9 lbs.

    For a plastic rifle it sure weight a lot. A standard M4 weight around 6 lbs.

  • jdun1911

    Dannyon,

    It could be the Massoud in 7.62. Magpul did not sell the right to it.

    As a rule of thumb DI rifles have better accuracies then their piston counter parts. So I doubt they will use the Massoud.

  • Cade

    I believe the other rifle shown in the second picture is the new Remington MSR.

  • Ken

    Considering the ACR is bulkier,its not really surprising it weighs more. One pound is a moot point. Im not a fan of polymer main parts on a military rifle. It gives it a “disposable” look, IMHO. Also, durability is in question.

    • http://www.thefirearmblog.com Steve

      I am not saying polymer lower is a good thing, but there once was a time, not long ago, when aluminum receivers were considered bad and plastic was not considered good enough for stocks.

  • Tom

    I see many new and improved military rifle designs.. but one thing is lacking.. a new and improved cartridge.. these new rifles are still all chamber for the crappy 223 or 5.56.. we need an new and improved cartridge and magazine system for these new rifles.. and get away of trying to see what we can fit into the current AR15 magazine..

  • http://www.sigsauerguns.com John

    Hey, this model isn’t showing up on Remington’s website yet. Is this actually slated for public availability? The design definitely resembles the SCAR…

  • D

    Magpul polymer isnt ok for a rifle but plastics that arent as good as Magpuls is ok for pistols.

  • D

    “why did the charging handle design changed so much during the evolution of the gun?first it was on the back,then near the end of the hand guard(and it was on both sides),and now,on the other side of the gun…”

    charging handle used to be above the ejection port area, like in the first pic, but it interfered with some optics mounts, so they moved it forward. Good change IMO.

  • jdun1911

    One pound isn’t moot. “More ounce more pain” or something like it.

    One pound isn’t much to people that watch TV at home but to a grunt that carrying 100 lbs on their back for hours, that’s a lot of pain.

    Every year there is one or two new cartridge entering the market. You know what happen? It dies one year later.

  • Gutao

    D
    i knew that part of the opctics,but the 2nd design(the one with charging handles on the front) was kinda nice and “unique”,so,why did they change?is there any advantages(becides the reciprocation)?

  • Ken

    Considering my weapon in the Army at one point was an M16A2 with a M203 on it,I consider 7 pounds “light”. No TV here. I understand the weight factor. I also understand that the weight of the gun is irrelevant because it is a necessary evil and will save your life.

  • jdun1911

    Ken,

    The M16A2 has a 20″ inch barrel and weight around 7.5lbs IIRC. The ACR with 14.5 inch barrel weight at 7 lbs. That’s a big difference.

    This rifle is design from the onset to be adopted by the US military. That is the goal of the rifle creator, Magpul. They have stated this many times and I think it is the main reason why the sold the rights to Bushmaster. Otherwise it would have been in civilians hands by now.

  • Ken

    Does that half pound make it a better gun? Anyone? I dont troll the internet for combat reports so…What does everyone think about the interchangeable barrel feature?

  • Mikeone

    WOOO more stuff we will never be able to buy!!!!

    Common Cerebus sell us the bolt gun at least !!

    This just makes me laugh .

  • DSS

    I am disappointed the forward charging handle was dropped. I liked the charging handle on the M16. I thought it was an ideal location for quite cocking. The rear charging handle makes this weapon look like a SCAR knock off.

  • Bobby

    Yet another reason to buy a different rifle.

    I’m sticking with my LWRC setup…

  • jdun1911

    Ken it sure does. You can ask anyone that been in Afghanistan. You can ask anyone that do high altitude fighting where the air is thin and every ounce weight a ton.

    Steve posted an article few months back where serviceman that came back from Afghanistan and Iraq with mess up backs. Too much weight was the cause.

    I rather carry extra ammo then carry a weapon that is one more pound heavier then it should be. It has been said here and in other boards that people will pay a premium to get a pound or two off their back.

  • Ken

    The Infantry will always be over burdened. Sadly enough. Maybe some combat veterans can chime in? In my opinion I would rather have a rifle that was slightly heavier but accurate,reliable and would take a guy down all the time versus a high maintenance,flimsy, and low powered rifle. Steve maybe a poll on this?

  • D

    not sure what yall are saying about a rear charging handle, it clearly is a forward charging handle. You can see it in the pic with the remmy sniper rifle. You cant see it on the other pics because you are looking at ejection port side.

  • SeanN

    i’ve weighed in on the weight issue before (infantryman, 10th Mountain, OEF VII/VIII), and while i concur with jdun that lighter is generally better, i don’t think half a pound is that big a deal. if you take a modern M4 which weighs, what, 7 lbs loaded? by the time you add the infrared, optic, and a flashlight, i’d bet you’re at 9-10 lbs. add a 203, that gets up to about 12 lbs, and each magazine weighs about half a pound…what i’m trying to say is that, as a man who’s carried a 12-ish pound 203, a 15 pound SAW, and a 25 pound M249, plus water, plus ammo, plus a thousand other things, when you’re carrying around that amount of weight, you really don’t notice half a pound. water bottles probably weigh about half a pound, but you stuff as many of those in your pack as possible, regardless of the weight. if the acr was half a pound lighter, that’d be swell, but that’s by no means a deal-breaker for me. in the great weight debate, i think the armor systems are a much bigger issue than a half-a-pound on a rifle.

  • uzim16

    nice! how much is it?

  • Rakkasan

    I was deployed to both Afghanistan and Iraq with 2/187th Infantry 101st. I did enough humping in the mountains and through urban environments to realize that no matter what, as a grunt, you will always be carrying way too much weight. I don’t think half of a pound matters when you are looking at carrying anywhere from 70 to 100 lbs in other gear…so I have to agree with SeanN on that point. Personally, I appreciate a heavier more stable rifle that might cut back on some of the recoil and help send home some of those followup shots, especially a rifle that is spec’d for automatic fire. You start firing 750 rpm with a 6 lbs rifle, you’ll be throwing rounds all over the place. I understand with full auto you can’t expect surgical accuracy, but that weight makes a difference in recovery time. Its easy to get hung up on the little stuff, but when it boils down to the nuts and bolts of it all, I don’t think that the weight of this rifle is what they’ll be up against when it comes to making this the next service rifle. Versatility and adaptability are this rifles major selling points, not the weight.

  • MHD

    It has been a long time since I carried a rifle in a hostile environment. But, experience from that time tells me that no matter where you shave weight, the “amount” you carry will stay the same. In other words, if you shave a pound from the rifle, you’ll carry extra ammo, water, food, etc. If you shave weight on armor, you’ll carry extra ammo, demo, water, etc. Infantry has been carrying between 50 and 100 lbs of gear since the Roman’s were kicking butt. Until we can get bearers to carry our gear, we’ll be hauling a lot of “stuff” around. In a hostile environment….what I want is reliable and effective. Weight would fall in there at about 3rd or 4th place.

  • Zquez

    One of the things that gets me is how the same gas system will work with different length barrels. If the carbine length is designed for 10.5 – 14.5″ barrels, wouldn’t there be some kind of reliability issue with using a carbine length gas system on a 18″ barrel? Didn’t the mid-length AR come about because it was better suited to the civilian 16″ barrels? Also, does this piston system efficiently handle suppressed as well as unsuppressed fire? I do have to admit that the ACR is starting to look a lot like the SCAR. Especially with that two-tone flat dark earth.

  • Cleen

    What is the expected msrp on the remington acr? when it finally comes out that is.

  • SkYLiNe17

    Apprantley its is going for around $1400 USD

  • Jake

    What I’d like to see is an ACR equipped with an under-barrel grenade launcher. Until a carbine is able to fulfill the roles of rifleman and grenadier, it won’t be adopted by the military.

    I don’t have much experience in the field (though I do plan on enlisting after graduation), but I can honestly say (for now) that I wouldn’t at all mind having the extra punch of a 40mm when and if I need it, even if it means a bit of added weight. Then again, the added weight can be a bonus, as Rakkasan and SeanN have pointed out– more weight equals less recoil and better repositioning, THUS closer grouping.

  • Jade Slade

    This is one ragin’ bitchin’ rifle. Shot one last month. It is cool.

  • Brenden

    Charging handle is forwar. Tha gas system has multiple settings for suppressed and unsuppressed firing so no undue stress is put on the system. The gas system is connected to each barrel so there is no issue with changing barrel lengths. A grenade launcher could easily be made to fit where the front hand guard attaches using capture pin and the same type of barrel clamp the tavor grenade launcher uses.

    ok in my eyes a pound dosent matter… if it was 2 or 3 i wouldent touch it but todays rounds are so accurate that you never need the 20in barrel a 14in is all ill ever need… im not going out to shoot flies out of the sky so if its 1in off at 200yards big woop… you should still be able to hit center mass witht the shorter barrel… honstly all i care about is hitting within the 5in circle of center mass im not lookn to shoot your nipples out so why be so accurate when it dosent matter,,,,,,,,just sayn and its truley an opinion so im just giving my 2 cents

  • paull

    just looked at MSRP at bushmaster $3000+ for enhanced.. that’s alot money.

  • Greg

    I saw the weapon on YouTube. An individual had posted footage of Shotshow in 2008 and 2010 and it was shown in both. I have to say definitively for myself that I prefer the 2008 version because it had the charging handle on both sides. this is convenient if the hand which you prefer to activate the charging handle were to let’s say be exposed to danger if you were to use it. I don’t know, I simply like having the option of using either hand. While it it true that the 2010 model can be charged from either side, you have to physically moved the charging handle to the opposite side, like the FN SCAR.

  • Eric B.

    I would REALLY like to see a side-by-side comparison of the ACR and the FN SCAR because these two will soon go head to head in competition for the replacement for the M16 family of rifles. What are the strengths and weaknesses of each? Which do TROOPS like?

    It seems to me that Magpul/Bushmaster/Remington need to make the ACR modular enough that, like the SCAR, it can be switched from 5.56 mm to 6.8 mm (or 6.5) because the military sorely NEEDS a cartridge with more pundh at distance than the current 5.56.

    BTW, word from one competitor in the on-going solitication/testing for the next U.S sniper rifle has it that the cool-looking Remington entry was dropped for accuracy reasons. As of August Bushmaster and Desert Tactical still had dogs in the fight. Interesting to see who wins that contract for a .338 Lapua cartridge sniper rifle. Will it be one of the two remaining American enteries or a foreign rifle?

  • Brenden

    Hey Eric, I actually did a research paper on modern assault weapons last semester, and going on features alone(assuming it works as it should) the ACR wins hands down. The quick change barrel on the ACR is tool less and faster, the ACR’s controls are more ergonomic, the ACR has a non reciprocating bolt handle, and on and on. On top of all this I can’t see how the ACR could possibly be more expensive than the SCAR.

    • FARCRY666

      TOTALLY

  • charles222

    Well, chiming in as a combat veteran…7 pounds of rifle isn’t very heavy. I humped 20-odd pounds of SAW in Afghanistan for nine months and eventually adjusted to the weight, even with about sixteen pounds of ammo along for the ride, plus IBA/MICH, assault pack with about sixty more pounds of gear in it…a rifle that weighs a couple more pounds than an M4 (which frequently gets hefty from the accessories you see infantry/cav scouts/SF/etc attaching to them anyway) is not that huge a deal.

  • craig B

    I saw video of a SCAR being fired on single and full-afuto and the REM-acr also, seems the masada has better controllablity. I am not military,but i do agree a 6.8 round would be more affective than a 556 round. I think i would prefer the masada ,but what about the prices, is it 3000 still? Are there any opinions on the differents on recoil of the SCAR and the Masada?

  • FARCRY666

    HEY HEY ACR IS LIGHTER THAN THE M4 AND IS LESS BULKY IT IS BETTER THAN ANY AR EVER IT HAS A NEW 6.8 ROUND THAT HAS POWER OF AN AK WITH ACCURACY OF A 5.56 ALSO ITS MORE RELIABLE THAN HK416 OR SCAR AND YES IT HAS BEEN PROVEN GO ON YOUTUBE AND TYPE IN BUSHMASTER ACR TORTURE TEST THERES THREE PARTS THEY PUT BIG CHUNKS OF IN IT AND IT STILL SHOOTS IN PART THREE IT JAMED CUZ THERE WAS MUD IN THE MAG HOUSING AND IT WOULD NOT GO IN THE RIGHT WAY BUT IT DID JAM BUT IT SHOT THE SECOND TIME THEY TRIED TO SHOOT AND IN PART 1 ITS BOLT DID NOT LOCK TO THE REAR CUZ HE WAS USING THE 1ST GEN PMAG NOT 2ND BUT HEY IT DID NOT JAM ALSO IT JAMED WHEN THEY TRIED TO SHOT IT WITH A CRAPPY KOREAN KNOCKOFF DRUM MAG BUT NO GUN SHOTS WITH A CRAPPY KOREAN MAG AND ALSO THIS WAS ALL AFTER THEY SUBMERGED IT IN MUD AND THIS WAS ALL WITH THE BOLT OPEN AND IN PART 3 IT WAS LEFT BURIED IN MUD FOR 5 MINUITES AND IT STILL SHOT WHEN THEY PULLED THE TRIGGER TWICE ALSO WACTH ACR OVER THE BEACH TEST ITS FULL PROFF THAT ACR IS BEST AND IF THAT DONT CONVINCE YOU ITS GOT A 5 POSITION STOCK THATS FOLDABLE AND A THREE POSITION CHEEKREST(VERY RARE) AND AND A FIXED STOCK WITH A 3 POSITION CHEEK REST AND FULLY AMBIDEXTROUS EVEN CHARGING HANDLE AND NON RECROPRACATING CHARGING HANDLE AND A POLYMER HANGAURD OR QUADRAIL OR A REMINGTON HANDGAURD THAT CAN MOUNT 4 ACCSESORIES(GRENADE LAUNCHER,LASER,FLASHLIGHT .etc) i would go with remington gaurd cuz it has rails and has many slits in it for good cooling and is real sexy its very compfortable and can use m16/m4 mags wicth means…extra mags yay!! also it can use m4/m16 barrels wicth means…extra barrels yay!!! and that is why the acr is the best

  • FARCRY666

    @jake i know right it must look cool

  • farcry666

    @TOM NO THE ACR COMES IN 5.56,6.5,6.8,7.62×39 AND THE BARREL CHANGES QUICKLY AND BIENG ABLE TO US AK47 AMMO WILL GIVE U SOOOO MUCTH AMMO WHEN FIGHTING 3RD WORLD COUNTRIES LIKE IRAQ,AFGHANASTAN,LIBYA.etc

  • farcry666

    @greg wat accually the one wit charging handle in front is on both sides

  • Eric B.

    1.The SCAR only has a reciprocating bolt handle B/C SOCOM decided they wanted it. FN can make it either way.

    2.I like the ACR better but the civilian semi-auto version (pictured) has the pistol grip & trigger guard molded in ONE piece so you’re stuck with the grip, like it or not.

    If I get an ACR I’ll cough up the $200. Class III stamp fee for the full auto version. My AUG is semi auto and now I wanna rock ‘n roll with an ACR.

  • http://none matvei

    Any news if the Bushmaster and Remington Lowers, uppers will be interchangeable, if Remington start releasing that accessory lower with a changeable grip, some bushmaster fans might want their ACR to sport a better grip, which would need a new lower. I’m guessing they will be compatible as a joint program.
