    Want….

    Interesting the varying angle of ejection. Sometimes they seem to fly nicely forward in both versions what would even work with lefties (bullpup) and sometimes pretty much backwards and sometimes pretty randomly even throughout one magazine (haven seen this at the AR15 e.g. as well).
    And guess the faces are pixaleted since using your nose as shell deflector doesn’t make you look sexy 😉
    Interesting!

    • Tom

      I wonder if the various ejection patterns were a result of using a mix of ammo as a demonstration of reliability with different types of ammo?

      • Cornelius Carroll

        That would be my guess. That’s one of my favorite ways of testing a new weapon.

      • Most likely their ammo just isn’t that consistent.

        • JumpIf NotZero

          It has nothing to do with the ammo. Which is CLEARLY all military ammo likely from the same lot. (Look at that facility, you really think they’re using some bullshit plinker rounds they found laying around?)

          It’s not varying ejection without a pattern. Look at the full auto shots. They start off ejecting 4-5, work up to 3, then end around 2. This is heat and left over gas in the gas system, both which are increasing until a terminal point in that full auto string.

          • That’s an interesting idea. To verify it, you’d have to see a bunch of different strings fired from cold weapons.

          • JumpIf NotZero

            An “interesting idea”… Of what I thought was common knowledge. 🙂 go watch some full auto M16 videos, they almost all do this of every mag dump

  • Aar0nC

    Looks pretty much like a Remington ACR. The bullpup version looks very nice! I wonder how will it stack up to a Tavor.

    • I remember talking to the Radom guys at SHOT. It’s very, very similar to an ACR, and they don’t really try to hide it.

      • dp

        If they want to sell it elsewhere then it is job for patent layers; if not they do not have to worry. Copying in one form or other is common.

        • I don’t know that they’ll have a problem. The external style is different enough, and not much of the design details of the ACR were proprietary.

          Also, I believe the intended customer is the Polish Army.

          • DiverEngrSL17K

            Good point, Nathaniel. However, I think all DP was saying was that as a whole, firearms designers of every stripe and every generation commonly adopt one another’s ideas — either directly or in modified form — if they see that they can be put to advantageous use, regardless of the intended end user.

          • John

            A good example is the AR-18 action, most short stroke gas piston rifles coming out nowadays are echos of its design

      • Rusty Shackleford

        Do you happen to know if the lower and selector switch is polymer like the ACR?

    • mechamaster

      bullpup MSBS versus X-95 Tavor… a bit difficult to choose..

      • gunhead

        Plus the DesertTech MDR

        • JumpIf NotZero

          Right, well, if we’re going to count lots of vaporware, keltec has like 5 bullpups now.

          • Thracian Beast

            I had an RFB .308. Put about 300 rounds through it and sold it when I looked at the design and read about how many problems people were having with theirs. I think the best gun they ever made was the P32. They should stick to that, handguns that work forever.

          • Stan Darsh

            I thought about buying one until the problems surfaced and even now they haven’t been sorted out. Too bad Kel-Tec doesn’t adapt the RDB/M43 for the .308 cartridge.

        • Rusty Shackleford

          If the MDR comes out, I’m sure the 5.56 version will cost as much as a MR556 and the .308 will be somewhere around $5,000.

    • dan citizen

      Anything not bullpup might as well have a wooden stock and ladder sights.

      • Cynic

        Sure if you like being unable to shoot offhand or weapons with none adjustable length of pull and poor triggers.

        • dan citizen

          Balderdash.

          I’ve shot some bullpups with great triggers, adjustable length of pull is not prevented by bullpups, and pffhand shooting is great.

          Barrett 99? Fantastic trigger pull.

          When I carried a high standard model 10, I found offhand shooting worlds better than anything available at the time. And the bushmaster arm gun… A great little package.

          Bullpups are the future.

  • Toms

    Remington patent infringement? Looks like a clone externally, Remington sold some ACRs to GROM were they copied, looks like it. The ambi bolt catch is definitely a direct copy. Still a nice gun that I would purchase for sure. FB Radom is a good manufacturer.

    • Mack

      isn’t the ACRs bolt catch a direct copy of the XCRs? I have no problem with a company taking good aspects from different weapon systems, i just hope the gun isn’t a copy but an improvement!

    • FORMOZA

      For sure it wasnt copied, cause grom was testing ACR long after RADOM made MSBS, all they copied is the looks. Same as CZ805 Bren looks similiar to SCAR.

      • dp

        …. and G36 even with those loose take-down pins.

    • mechamaster

      Err.. from my Point-of view, actually it’s like slightly improved brother of ACR.. with full ambidextrous control, bolt, and ejection port that ACR doesn’t have.

    • chris22lr

      “Externally” is a good word here. MSBS is based on AR-18 short stroke piston design (just like ACR, and other modern piston driven carbines), but basic principle of Polish project was to make one upper which would fit both conventional and bullpup firearms. You can’t have it with ACR or SCAR.
      First working prototypes were very rough and bulky – think of uglier SCAR or Bren CZ805S. Then an external company prepared design of “outer shell”, which would fit already made mechanisms. This designing team was very inspired by Magpul Masada, and you can see it in final prototypes shown in the video. But MSBS is so much different from Masada, that lawsuit won’t happen. Actually MSBS is already patented, without any protest from Freedom Group (maybe they just don’t care).

      And BTW: it wasn’t GROM but BOR – our Secret Service – who bought ACRs. It was in 2008, when first bulky prototypes of MSBS were already made.

      • RNF

        BOR never bought ACR, they were testing them but finally decided to field SCAR’s. Off course GROM never bought them either. Bushmaster sold non disclosed number (more then ten) of ACR’s to officially never named unit of Polish Military. As the name of unit was never confirmed the Sluzba Wywiadu Wojskowego (Military Intelligence Service) soldiers where photographed with ACR’s in Afghanistan.

      • Jay

        Actually the “bulky prototype” you were talking about was just part of the whole program. From the start they did two families of prototypes, that are going to be merged in the latest stages of developement.
        One that focused on, tested and refined the functioning mechanism and one that refined the externals and ergonomics. The “ugly bulky” one was the one who’s goal was to refine the internals and function. It didn’t matter how it looked. That way, that team could focus on function.
        The way the rifle looks now is the final stage, where the two aspects of the design were merged into one.

  • USMC03Vet

    No glow belts? Not operator enough!

    • 11b

      Sergeant Major will be disappointing in their level of safety.

  • BrassAttack

    Man, that brass was bouncing straight off his lips? Otherwise, really cool rifles. And they also have the one surefire magazine that won’t cause a jam…jealous.

  • Adam aka eddie d.

    Both versions are very promising, especially the standard configuration.
    Radom really did their homework on these guns.
    Ambidextrous, huge magazine release (bolt release also ambi), ejection can be changed upon field strip via simply removing the port cover, screwing the deflector onto the other side, and turning the bolt, charging handle is on both sides and non-reciprocating, barrel can be changed without a torque tool, stock is foldable, cheekpiece is adjustable both in angle and height.

    The only -possibly- negative thing about this gun that caught my attention is
    the top rail is fairly thin above the charging handle.
    This can mean two things: a long term durability issue (not very likely though ) and the charging handle can interfere with scope mounts (much more likely).
    Since it’s quite far back on the gun, you’ll be forced to place your optic(s) on a certain part of the rail.

    Good news is Radom plan to produce a civilian version of both the standard config and the bullpup. American export plans have been confirmed (the reps mentioned it at Shot Show) , hopefully there are also plans for Eropean distribution.

    • Rusty Shackleford

      That would be nice to have these on the American market. Although it would also be nice to have these available for our European brothers.

  • Dave Gibson

    This was a test? Looks like marketing material.

    • dan citizen

      But if you buy this weapon system today you get a free sling!

      I know, you’re thinking this is too good to be true, this fine sling alone is a great deal. Many folks are gonna order this just to get the sling! And if you call now you can get 2 rifles for only double the price!

      Tactical Operators are standing buy!

  • echelon

    So much want. It’ll be the ACR that Freedom Group/ROC/Bushmaster/whateverthey’recallingthemselvesthisweek should’ve produced. Still waiting for my different barrel lengths and caliber conversion kits there Remy….

  • efred1

    Impressive. One question: How come the US military is still stuck with a 50+ year old design, that has been proven time and again to be inferior to several weapon systems on the market today?
