This stripped upper (no BCG or charging handle included) delivers excellent performance and versatility in a lightweight package.
The heart of this upper is a 10.5-inch chrome moly vanadium steel barrel with a carbine-length gas system, treated with a durable nitride finish for superior corrosion resistance, extended barrel life, and smoother operation. Chambered in 5.56 NATO with a fast 1:7 twist rate, it stabilizes a wide range of bullet weights (55-77 grain) for reliable accuracy whether you’re running FMJ, match ammo, or defensive loads. The barrel features an A2 flash hider on 1/2×28 threads, a .750″ low-profile gas block, and an M4 barrel extension for MIL-SPEC compatibility.
Topped with a 9″ or 10.5″ lightweight M-Lok free-float handguard, this upper offers ample real estate for accessories like lights, grips, lasers, or sights while keeping weight down for better maneuverability and faster handling. The forged 7075-T6 aluminum A3 flat-top upper receiver is hard-coat anodized black for maximum durability and a sleek appearance, built to strict MIL-SPEC standards.
Whether you’re assembling a short-barreled rifle, AR pistol, or custom home-defense setup, this PSA 10.5″ 5.56 upper provides outstanding value without sacrificing quality. Pair it with your choice of bolt carrier group and charging handle for a complete, high-performing build. Backed by Palmetto State Armory’s reputation for affordable, American-made components.
