Taiwan 9mm MSR Submachine Gun Prototype

Last year we published photos of the service rifle being developed by the Taiwanese military. According to the Youtube video embedded below they are also developing a 9mm submachine gun. The submachine gun is patterned after the rifle and probably shares a number of common parts. It has a folding buttstock (someone on the video says the stock has been 3D printed and they are testing different designs), ambidextrous controls and a full length top rail. The barrel looks to be about 7″ in length.

Anyone who has been visiting TFB for a while knows how much I love seeing new submachine guns. After a long hiatus, when sub-caliber PDWs and M-forgeries took the spotlight, they are slowly making a comeback. Now if only Ruger would bring back the PC9 Carbine …

    Instead of a Ruger PC-9. How about a Ruger PC 5.7. or 4.6. Or a PC7.72×25.
    Lets try something a bit different.

    • mechamaster

      Euhm.. To ease ammunition logistic supply and ‘general user’ that doesn’t have access to exotic PDW ammunition like 5,7 or 4,6 and to appeal the international customer.. IMO.

    • Blake

      If you mean 7.62×25 Tokarev then I’d be happy with that 🙂

  • Bruce

    PC-9 would be fine with me!

  • 44

    updated Ruger Deerfield Carbine 99/44 & hi cap magazines are what you all really mean.

    • iksnilol

      Or the Marlin Camp Carbine (maybe make it take standard pistol mags?).

      • Steve Truffer

        Deer-field style gun that takes DE mags?

        • iksnilol

          On the right track.

          Would be better with a modernised DE, double-stack mags (as the Kel-Tec PMR-30 does).

  • mechamaster

    This time, UMP-SCAR.

  • Kovacs Jeno

    Brugger+Thomet APC9 clone

  • 1leggeddog

    That just looks like an FN SCAR

    I wanted the guy holding it to remove his hand from the magwell to see if it was just the right size or the mag or the same size as the original but with an adapter.

    It seems like the gun has a lot of wasted size in it. The sight is way above the boreline for something meant to be used in close ranges. Ok, they want to make it compatible with their new rifle, parts wise, but i still think it’s a bit too big.

      Extrusions look alike… Who knew 😉

      Looks like SCAR – extrusion.
      Looks like APC9 – extrusion.
      Looks like UMP – not an extrusion, but could have been

    If you shot someone with the subject of this post, and someone else with this nifty little machine made almost 100 years ago, the medical examiner would not be able to tell the difference. This is not progress.


    • JumpIf NotZero

      …. Yea… I’ve long been advocating that the X/M2010 is basically pointless because we already had the M1 Garand, and they shoot a similar projectile and will both make people stop walking about…

      Oh wait, no, that’s stupid, now I get it.

      • bbmg

        I’m afraid your analogy doesn’t hold up. First off, the equivalent to the XM2010 from the Second World War would be the Springfield M1903A4.

        Secondly, take two snipers of equal ability, give one a Springfield and the other a XM2010, and have them duel – do you think it is clear cut who would win?

        Imagine a similar scenario where two pilots of equal ability were to duel, one in a P-51 Mustang and another in an F-22 Raptor. There would be no doubt that the most likely victor would be the Raptor pilot. Firearm technology is simply not advancing at the rate it should, possibly because the individual infantry weapon is really not a major factor in deciding who wins wars. A platoon of soldiers with the best infantry rifle would be wiped out by an enemy with better artillery or air power.

        • JumpIf NotZero

          Oh sure… I’m sure my analogy needs work… because I just picked two guns at random without any thought at all for how they are seemingly the same and actually vastly different…

          Much like your original post :

          • bbmg

            I would appreciate if you could elaborate on the vast difference in terms of performance and effectiveness that exists between the subject of this post and the Bergmann MP18.

          • ArcRoyale

            It doesn’t use that awful snail drum.

  • Esh325

    Yep, everybody says SMG’s are dead but yet they still keep making them. I mean there must be something a short barreled .223 assault rifle can’t do that a submachine gun can. I’m guessing it might have something to do with noise and blast levels? In doors a short barreled .223 is probably to be much louder than a 9mm is. Less bullet deflection with a 9mm? Easier to controll in automatic/bursts?

    • Michael R. Zupcak

      Cheaper to shoot, less chance of over-penetration

      • iksnilol

        Cheaper, easier to suppress, ammo commonality.

        Here in Norway most police use MP5s and 9mm pistols, that way they only need 9mm ammo. Only exception is police snipers who use .308. Those are used rarely, though.

    • Guns are inanimate objects!!!

      Assault rife what’s that? I know what a high power rife is but I’ve never seen an assault rifle…….
      The AR in “AR-15” rifle stands for ArmaLite rifle, after the company that developed it in the 1950s. “AR” does NOT stand for “assault rifle” or “automatic rifle.” AR-15-style rifles are NOT “assault weapons” or “assault rifles.”
      And “AK” stands for “Avtomat Kalishnakova”
      Guns are inanimate objects they have no life so the can not assault anyone..FYI

      • John Hogen

        Assault rifle is a rifle that fires an intermediate cartridge, so Esh325 is correct. It’s only Americans that warp these terms to circumvent gun laws by producing 5.56 NATO AR-15 with no stocks and call them pistols…

  • BattleshipGrey

    Anyone else find it interesting that they REFUSED to show the mag well? They did everything in their power to obscure it from the camera. That was the first thing I was looking at to see if it was as hideous as the new Taurus carbine.
    My other question was at what point will multicam be so widely adopted that it starts causing blue on green losses?

  • LCON

    Kinda Reminds me of the CZ Scorpion Evo 3A1
