10.5" 7.62x39 Medium Carbine M-LOK Upper Assembly

Big-bore performance in a compact, American-made upper.

The 10.5" 7.62x39 Upper Assembly delivers reliable, short-barrel performance with serious punch. Built on a mil-spec forged upper, it features a medium-profile, nitride-finished barrel with a 1:10 twist—optimized for stabilizing 7.62x39 in compact configurations.

A carbine-length gas system and steel low-profile gas block ensure smooth operation, while the M-LOK free float handguard offers modularity for mounting lights, grips, or other accessories. Each upper is assembled with Permatex 242 and AEROSHELL 33MS on all torqued components, ensuring longevity and reliability under real-world use.

Topped with a nitrided A2 flash hider and backed by a Limited Lifetime Warranty, this American-made upper is a no-nonsense solution for building a compact AR that hits hard and runs clean.
