PWS MK116 MOD 2-M Upper Receiver 7.62x39 - 16.1" Barrel
The Primary Weapons Systems (PWS) MK116 MOD 2-M is a top-tier long-stroke piston upper receiver specifically engineered to handle the 7.62x39mm cartridge with unmatched reliability. While many 7.62x39 AR builds struggle with gas port erosion and fouling, PWS solves these issues using their legendary Long Stroke Piston System, inspired by the ultra-reliable AK-47 design but refined with AR-15 precision.
This MOD 2-M variant is the flagship of the PWS line, featuring a fully forged upper receiver that eliminates the forward assist for a sleeker, lightweight, and snag-free profile. The 16.1" precision-rifled barrel is crafted from 41V50 Chrome Moly Vanadium steel and finished in Isonite QPQ for extreme durability and corrosion resistance. The heart of the system is the 3-setting adjustable gas block, allowing you to perfectly tune the rifle for suppressed use, varying ammo types, or adverse environmental conditions.
Equipped with the innovative PicLok™ handguard, you get the best of both worlds: M-LOK mounting surfaces along the length of the rail with integrated Picatinny sections at the front for solid mounting of lights and lasers. Finished with a Radian Raptor ambidextrous charging handle and a PWS FSC 30 compensator, this upper is a complete, drop-in solution for shooters who want AK-47 power with modern AR-15 ergonomics.
