Over the past few years, Primary Weapon Systems has been pushing the limits of what is possible in AR-style firearms, and this is no exception. The MK116 MOD 2-M 7.62x39 Complete Upper makes it possible to build an AR in the same 7.62x39mm caliber as AK-47 style rifles. This upper receiver comes complete, so all you'd need to do is add a compatible lower and you're good to go.

  • Operating System: PWS Long Stroke Piston System - 3-Setting Adjustable Gas System
  • Caliber: 7.62x39
  • Barrel Length: 16.1"
  • Gas System Length: Mid-Length
  • Barrel Twist Rate: 1:10
  • Muzzle Velocity: 2374 ft/sec
  • Muzzle Device: FSC 30
  • Upper Receiver: PWS Proprietary Piston Upper - T6 7075 Forged with Anodized Finish
  • Handguard: PWS PicLok™ 15" Handguard (1.7” width, 2.25” height)
  • Charging Handle: Radian Raptor™ Ambidextrous Charging Handle

This upper will fit on compatible 7.62x39 lower receivers and, in effect, gives you the benefits of the AR system, especially the controls of the firearm, with the operating system and caliber of the AKM. This upper is ideal for people who are in the process of a build of a firearm that is a hybrid of AR And AK design features. With premium parts ranging from the charging handle to the muzzle brake, the Primary Weapon Systems MK116 MOD 2-M 7.62x39 Complete Upper gives you a good head start on your new build.
