JSC KBP Instrument Design

JSC KBP is a Russian design firm that designs weapons.
This picture piqued my interest. As a fan of the Magpul FMG, I had to find out more about the similar looking gun below.
It is called the PP-90M. It was designed in the 90s and is chambered in 9x18mm Makarov.

They also make a PP-90M1. A non folding sub machine gun but this one uses a cylindrical magazine.


This revolver is rather interesting. It is the OTs-38, 7.62 Stechkin Special Revolver. The swing out cylinder doesnt swing out like you think it should. It opens on the right and hinges out like a car door. If that wasn’t strange enough, it appears this revolver fires from the bottom cylinder similar to a Mateba or Chiappa Rhino.

According to the KBP website, the OTs-38 uses a special 7.62 mm SP-4 round.
Noiseless and flameless shot is made due to special SP-4 cartridges with power gases localized in the case. The OTs-38 revolver can be rightfully called noiseless, since the noise level when making a shot and dry firing is practically identical.

    Folding gun = take my money!!!

    • iksnilol

      Eh, according to Max Popenker it wasn’t sucessfull. Something about it being very uncomfortable to use (everything is made out of stamped steel).

      • Adam

        Not that bad actually…. Mate carries one in the Philippines..

        • iksnilol

          Are they actually in use!? I thought they didn’t get much past the prototype stage.

          Dayum. Looking at it again you could probably make it more comfortable with some tape and /or paracord.

          • Adam

            You can buy them as a carry home defense gun in the Philippines for about $1000 USD.. Actually, you can own just about anything on a license in the Philippines… Its a machine gun lovers paradise.

          • iksnilol

            I read up on it more, they make a 9×19 version aswell. I really want one now.

            Regarding the license thing, how much in bribes to get MG license?

          • Adam

            Its the Philippines, you have from type 1 to 2 is for general handguns and small caliber rifles And you can..own up to 3…Mind you, that means you can walk in and buy a Mac 11, Glock 18, or a 1911.. Type 3 to 5 covers everything you could possibly dream of. And a type 5 is unlimited number… For instance, You want that nice shiny new M4 with M203 fitted or that H&K G36C you can own it.. They tend too be a bit iffy on belt feds, but you can get them still..

          • iksnilol

            Sounds nice, could check out the cracks.

    • USMC03Vet

      It’s the robocop 2 gun!

    • Michel_T

      You’re dealing with the Russian… seems like $$ is only part of the equation when you want something from them… and forget about getting any kind of support from the factory.

      A few years back, an acquaintance was able to convince TSKIB SOO to sell him some RMB-93 (Lynx) shotguns… Fast forward a decade, I’m still waiting for choke tubes to show up…

  • Jeff Smith

    Does the revolver have two barrels? It looks as if there is a barrel in the traditional place that has been covered.

    • BattleshipGrey

      I dunno but it looks pretty aggressive.

    • Charlie Taylor

      Nope, the thing on top is a laser sight i believe

      • patrickiv

        I hope it actually does something.

    • Iggy

      Yep, based on Max Popenker’s sight, it’s a laser sight.

    • Michel_T

      The barrel is at the bottom and the lug is at the top.

  • Pete

    This revolver fires the famous “silent ammo” that we used to hear about. The Soviets never minded if their weapon prototypes blew up and killed a few soldiers during the test phase, so they innovated a lot more than we did. To answer the inevitable question, the ATF has classified EACH round of silent ammo as a “silencer” so each round requires a $200 tax stamp.

    • Ethan

      whaaaaaaaat?!? FTATF

      • Kurt Akemann

        Yep, the ATFtook notes from Chris Rock on this one. And while I find Chris Rock uproariously funny at times, I don’t like it when a government agency’s decision-making resembles a comedy act.

        • Zachary marrs

          Its been like that since like, ever

    • Michel_T

      In case some people missed it… I’ll assume that Pete is talking about the SP-4 captive piston ammunition.

    • Why the hell would someone, or rather anyone, die or even be injured during the development of a cartridge? That’s really puzzling. I mean, to ensure safety testing a handgun you only need a couple of metal or plexiglass sheets and a piece of rope (same high-tech gadgets they used then and still use now). I can see backyard DIY hillbillies getting hurt testing their home-made monstrosities, but this is the Instrument Design Bureau – a place that designs modular tank turrets, guided AT missiles and A-A missile systems. Which is kinda in the headline.

      And besides, what the hell would a army soldier do in an R&D lab?!

  • M

    The Ares FMG was the first nondescript folding smg.
    there’s also the: the Hotchkiss Universal SMG but deploying it was awkward and not as fast

    • Tom

      The Ares FMG achieved fame with Robocop 2 and not much else. I guess that for anyone who wants it as more than a novelty a conventional SMG or short rifle (think AKSU) is just not that much bigger and certainly a lot easier to deploy and useful.

  • John Yossarian

    FTATF indeed. Every feature I could possibly want is in that machine and its ammo, including the swing out cylinder.

    If you think of holding the barrel and lug with the majority of your left hand and hinging out the cylinder with your left thumb: That puts the cylinder on the same side of the frame as your right hand. It seems like it would be way easier to load without having to reach over the frame as on a typical, swing-out to the left design. And while your left hand is hinging out that cylinder, your right hand could be going for the next moon-clip.

  • noguncontrol

    i love silent ammo and the guns that shoot them, perfect for civilian self defense, in the home or in a car. to hell with the nfa and to hell with the batf!!! both need to die!!!

  • wildbillb

    so did the texas flashlight knock off the russian PP-90M? i’m so confused… but would buy either.

  • gunslinger

    folding gun? Sons of Guns “invented” this, right?

    nevuah ben dun bafor

  • Dropship Ace

    I would love to know more about the OTs-38 Stetchkin.

  • LCON

    The Folding SMG in Robocop2 was the UC-M21 from Dave Boatman. It was based on Stoner’s FMG but Boatmen’s had a carry handle sight and dummy Telicopic radio antenna. The Stoner Ares FMG looked like the pp90 there.

  • CavScout

    Watched the old Magpul video. Turns out it’s a modern copy of a Stoner design! We had Stoner and Browning… I think the US has made its contributions to the world of small arms.
