Bushmaster Releases Factory SBR ACR

While not exactly “breaking news” material, Bushmaster ACR fans have a reason to to be happy this week. The company is offering a factory short barreled rifle (SBR) configuration of their ACR platform.

For regular readers, the Masada/ACR saga is well known and as we approach the 10 year anniversary of its original debut is coming up next year.  My question to all of you: is the this platform still relevant in a world of ARs, SCARs and other Modern Sporting Rifle design evolutions? Who owns an ACR and is it your “go-to” defensive rifle?

I am not trying to start a sh*t storm – I’m genuinely interested in the ACR’s relevance in a flooded market a decade since its original development.

Post up your experiences in the comments section below.



  • Short Barreled Rifle (SBR)
  • 10.5″ Cold Hammer-Forged Barrel
  • Three-sided aluminum hand guard with integral MIL-STD 1913 rail for accessory mounting
  • Includes AAC® Blackout flash hider
  • Includes 30-round PMAG magazine
  • Chambered in 5.56
  • Includes AAC 51t flash hider adapter
  • Folding and collapsing stock
  • Ambidextrous safety, bolt lock, and mag catch
  • Adjustable gas piston system

Bushmaster ACRs combine unstoppable gas-piston reliability with the ability to quickly change barrels, and calibers in minutes. Ambidextrous fire controls easily accommodate left- and right-handed shooters, and telescoping stocks with adjustable length of pull in folding or straight versions complete the world’s most adaptable lineup of MSR models.

  • No one

    All the failures of the regular ACR is a smaller package!

    • Juggernaut

      The ACR is really showing its age.

  • EdgyTrumpet

    And still no caliber conversions ?

    • Wow!

      Go to a gunsmith and have him make a barrel for you in whatever caliber. The lower is of course not the registered part, and you can get a new lower milled or 3D printed by other to accept 9mm or possibly AK mags.

  • mechamaster

    They should release the ACR-IC ‘Individual Carbine’ compact/standard but with tweaked lightweight receiver material ( magnesium subtitute )

    Even it’s lost the Quick-Change Barrel function, but whatever… the caliber conversion can be done with switching the upper receiver with different caliber like the AR15.


    • SP mclaughlin

      That ACR version just looks downright hideous.

      • mechamaster

        The “magnesium” receiver. lol.

        • SP mclaughlin

          Not just that but the new handguard and removal of the stock hinges do a number on the aesthetics.

          • H.C.

            The folding stock is an option, The non folding stock was developed to meet the IC weight requirements.

    • SomethingSomethingDarkSide

      That makes too much sense. We’re talking about Freedom Group here…doubt there’s a serious shooter in the whole bunch (at least of those who are calling the shots).

    • H.C.

      The “quick-change” isn’t lost on the REMDEF ACR, it’s just no longer tooless. It takes a spanner wrench. The integrated handle was removed to save weight. Wich is the downfall of the ACR now. The REMDEF is the best looking ACR, and what all new ACR’s should be. 6.2 lbs unloaded.

  • 22winmag

    Fools and their money

  • KestrelBike

    I got an ACR back in about… 2011 or something. Paid $2k. I really like it. The only thing I don’t like is how front-heavy it is.

    It *appears* that you can get just the 10.5″ barrel, and after getting your stamp (in a million years) just pop it into the upper receiver and you have an SBR ACR. I’d like to see whether an ACR with a short barrel has a better balanced feel compared to the original 16″ version I have.

  • derpmaster

    “please, throw some more money into our ill-conceived cash furnace”

    -ACR product team

    • Pete – TFB Writer

      For this money I’d be buying a B&T APC223 every day and twice on Sunday.

      • derpmaster

        A range demo day with their full product line is a minor dream of mine.

      • Lupinsea

        So would I.

        But ACRs are going for between $1500 – $1600 brand new online. Which is not B&T money.

  • Patrick Karmel Shamsuddoha

    At this point H&K has more Calibers in the 416 line than Bushmaster and the ACR… thats when you know you messed up …

  • David Kiwacka

    The ACR is a awesome carbine, not without its faults but what isn’t. It has been my go to rifle for over 6 years. Zero failures with the rifle (few mag issues but it causes the same in my AR’s) and pushing the 10K round mark. It is nice to see SOMETHING from Bushmaster for once. The ACR has a pretty good aftermarket community, about like what it was for the AK a several years ago, look at it now. Here is to hopping BM keeps working on them and people start picking them up more. Pushing 10 years is pretty good, if the platform was going to drop off it would have by now.

    • Big Daddy

      get new mags

    • Lupinsea

      Hear hear!

      Hadn’t given the ACR much thought until a couple months ago. Did some research into them and came away very impressed. There is a lot of outdated info and preconceived notions (that Bushmaster earned the hard way at the start). But the ACR now is a great rifle. I wish it the best and continued production.

      I would hope people re-evaluate the ACR. It’s worth it.

  • Michael E Thompson

    Bushmaster killed the ACR with an artificially high price tag, but the Polish Military apparently fields some. However, they need to cut the price before the cut the barrel. Not as good as a SCAR, or CZ Bren for that matter.

    • Juggernaut

      Well, when you pay $3K+ for a SCAR16 the thing should outshoot about everything on the planet- which it doesn’t.

      • No one

        I could see a case for the SCAR if full auto actions were civilian legal, but unfortunately this isn’t the case.

        Hell, I could see a real case for the SCAR-16 if they at least updated the 3rd gens to the FNAC standard they submitted to the IAR competition that added alot of features it needed and cut many that weren’t, but considering the US Army might own the design now, sadly I don’t see that happening.

      • Concerned Third Party

        My SCAR16 only cost me $2100 new, where are you getting 3k+ from? Panic prices on gunbroker?

    • Chris22lr

      Polish Military Intelligence Service which is part of Polish Military, but not a subordinate of Polish Armed Forces. A total of 13 Bushmaster ACRs with 10.5 and 14.5 inch barrels.

      They could get regular M4s from JW GROM armoury (JW Agat and JW Nil got GROM former M4s – actually also Bushmaster M4A3), but there’s that unofficial competition among Polish special forces/units “who got the coolest toys”. This way GROM have like 5 FN F2000s “for evaluation purposes”, Police bought 5 HK416C (first known user of these guns) and one of each Barrett M82 and McMillan TAC-50A1. Cops are probably the leaders in this contest, since each year they have 2-4 tenders where they buy some Gucci (Larry Vuiton?) stuff. But hey – taxpayers don’t ask any questions, so it’s all good isn’t it?

  • Guest

    My opinion, Bushmaster should have dropped the quad-rail fore end a long time ago. The ACR is supposed to be a sleek looking platform, not bulky like that quad rail. They should put the Remington guard on or design something m-lok or keymod. I know this comment is kinda irrelevant based on the failure of the ACR, but I still like the rifle and wish it would go back to it’s roots…

  • SerArthurDayne

    If only they had had the sense to produce the real deal Magpul Masada, and a 7.62×39 conversion kit. Everyone would have loved it. But this? 8 years and still no real kits or promised accessories. Pfffffft.

    • Lupinsea

      No promised accessories? Such as:

      Four different rifle configurations
      Four different barrel lengths
      Two different hand guards
      Three different stocks
      – and –
      Two different colors for all of the above

      It IS lacking in caliber options. It certainly would be nice in a cheap 7.62×39, no doubt. But I’d say it has a nice assortment of factory accessories.

  • TheNotoriousIUD

    Does it really matter at this point?

    • SignalFromTheRim


  • Reality

    2008 wants theyr Quadrails back. Why not Mlok?

    • BillC

      Because it’s Bushmaster. It’s a failed product execution. Just look around the comments. “I like my ACR, but…”

  • valorius

    I find it hard to imagine anyone would pay over $2 grand for one of these things.

    • Lupinsea

      Me too.

      Which is why they are between $1500 – $1600 brand new retail.

  • Shaun Connery Oliver II

    Sorry but you blew it big time when you failed, I do mean FAILED, to deliver on your promise when came to the conversion kits. So yeah, I will stick with the SKELI X11 for the time being.

  • BillC

    No mention of its twist rate? I’m going to assume another 1/9 failure again.

    • No one

      Not to defend the ACR because I have absolutely no reason to defend this garbage rifle, but 1/9 Isn’t exactly a terrible twist rate for 5.56x45mm/.223 Remington (assuming you’re using a proper chamber that supports both). It’s not mil spec but it’s still good enough to stabilize 77gr lead rounds like SMKs and solid copper rounds up to around 70gr while still being good enough for lighter varmint loads (why you’d use an SBR for varmint hunting, I don’t know, but not really the point I’m trying to make.)

      1/8 and 1/9 are easily the best compromise twist rates if you don’t want or don’t have the option for a 1/7 mil spec twist rate.

      • BillC

        Brian Litz begs to differ.

      • int19h

        1:9 does not reliably stabilize 77gr bullets in all conditions (think humidity, elevation etc).

        • iksnilol

          Are you in a humid mountaineous area?

          • int19h

            Yes, PNW.

    • Wang Chung Tonight

      I’m amazed they don’t even list a twist rate. The technical sophistication of the average MSR consumer has increased significantly since 2010. People now actually understand the value of a 1-7 twist. Or do they?

  • Vitor Roma

    If they just removed the quad-rail…

  • Bucho4Prez

    Some pasta on it’s way to the wall.

  • lol

    Why would you buy this when you could own a scar for less..

    • BillC

      Why would you want to own a SCAR 16 over an AR from a company that makes duty grade rifles (BCM, SOLGW, et al)?

  • Malthrak

    Why bother at this point?

    The ACR had its time to shine and Bushmaster dropped the ball and still hasnt delivered on the primary premise of the rifle (the Adaptive part). The market moved on loooong ago.

  • Harry’s Holsters

    If bushmaster played its cards right they could get a second chance with the ACR we are all begging for something different than an AR but we want it with an MSRP under $2000.

    • Jared Vynn

      They would probably have to hit around $1000 if not under to stand a chance. Especially with how demand has now dropped.

      • Harry’s Holsters

        I don’t know if they have to go that low. A street price around $1600-$1700 would let it compete with some of the higher end ARs like DD. Everyone already has a couple of ARs so they’re going to want something different.

  • Just say’n

    Looks different, but what can it do that an SBR AR can’t, for 1/3 the cost?

  • Christian Hedegaard-Schou

    Oh neat. TIL someone still makes the ACR.

  • GunnerMcGunner

    One of my favorite weapons for … Call of Duty.

  • .45

    All I know is that the ACR was decent in Call of Duty…

    • BillC

      And that is what drove a lot of sales for it initially. Kids with a lot of money, to spend on something that they knew nothing about. An overweight rifle, with a M4 barrel profile (whyyyyy????), with a1/9 twist, from Bushmaster/Freedom Group.

  • BillC

    Calm down, dude. The ACR sucks. It exhibits what was advance thinking, a decade ago; but not executed to intent, and the changes have been few to keep it current. Wow it came out with Picatinny rail a few years ago. Also, an M4 profile barrel? Seriously? Stop trying to say the ACR is great, all because of what it could have been.

    Knock it off. It failed. It’s not a bargain compared to the SCAR 16 and the XCR, both of which have their own issues and deficiencies. (the XCR sucks worse and the SCAR 16 has no added value over a well made AR). That’s like trying to say Crap A is better than Crap B, because it’s slightly cheaper.

    • TW

      Everything you say if opinion. I agree that the ACR is a good gun. It shoots nice, it is reliable, and has great ergonomics. All while being less than a SCAR 16S. Yes they had a shaky start and no support, but it is still a good gun. Do I like it over my ARs, maybe it has points about it that do make it better.

      Overall you hating it is your opinion. In mine it is a good gun that does what I want it to do.

  • mig1nc

    You can get a Beretta ARX for around a grand. I think that’s what you have to compete with if you want a folding stock piston gun in a heavily flooded market which is in the midst of a post-election downturn.

    • mig1nc

      Don’t get me wrong, I like the ACR. I would have bought one a while back if I had the money at the time, but now I’m looking at a different market.

  • FactChecker90803

    No thanks, will waite for the fully ambidextrous SKELI X11.

  • Wow!

    Between the SCAR and the ACR, I would always go for the ACR. Most of the complaints are about broken promises, not really performance issues. That said, between an ACR and an M16 variant, I think the M16 does everything I want at a much lower price. ACR is a bit heavier than an AR, but I do like the ergonomics a lot better, and I made myself a x35 barrel so I have the 2 main rifle calibers I shoot in one compact package. It’s one of those things that are nice if you have it, but you don’t need it. I didn’t buy my ACR, I got it as a gift. I probably would not spend over $1,000 on any stock rifle, but since I do already have one in my hands I won’t be letting go of it.

    At the price of an ACR or SCAR, you can save a little more money and get an MCR belt fed upper which IMO is a lot more function for the dollar vs what is mostly a dress up kit of an AR.

  • jim

    Leaving out the emotional arguments about what it isn’t (no caliber changes and other features that weren’t or haven’t yet rolled out, and aesthetically not pleasing), and addressing only what it is, what I’m hearing is that the cons are:
    -a little front heavy/overall heavy
    -1:9 twist rate
    -Expensive compared to AR’s
    Does this sum it up?

    More questions:
    -can you get a barrel with a different twist and profile easily (does it take barrels made for an AR?)
    -how easy is it to break down and clean?

    I like the ACR pictured in the comments below (desert tan?)
    It does seem silly to have an M4 profiled barrel since the cut for the grenade launcher is buried under the hand guard. Was this a weight saving strategy?

  • Ced Truz

    $2,249.00?!?!?!? Did they hide gold somewhere in there?

  • jimmyjet

    $2,249.00? Puhleez!
