PWS MK116 MOD 2-M Complete Upper Receiver 7.62x39mm 16" – AR-15 Platform

The Primary Weapons Systems MK116 MOD 2-M is a complete upper receiver chambered in 7.62x39mm, designed for shooters who want AK-caliber ballistics in an AR-15 platform. The 16-inch barrel delivers optimal velocity for this intermediate cartridge, and the MOD 2-M configuration includes PWS's long-stroke piston system for reliable function with steel-cased ammunition and reduced maintenance compared to direct impingement.

This upper features a forged 7075-T6 aluminum receiver with a black anodized finish. The free-float M-LOK handguard provides mounting flexibility for accessories while keeping weight manageable. The upper comes complete with bolt carrier group, charging handle, and flash hider. Installation on any mil-spec AR-15 lower is straightforward—verify your lower is compatible with 7.62x39mm magazines and feed geometry before installation.
