Palmetto State Armory

Overview

The PSA 10.5" 5.56 NATO Upper Receiver is a complete assembly designed for the AR-15 platform, featuring a compact 10.5-inch barrel that's well-suited for shorter builds, providing improved maneuverability while maintaining effectiveness at close to mid-range distances. The carbine-length gas system ensures reliable cycling and performance, with a 1:7 twist rate that allows for better stabilization of a variety of bullet weights. This upper is commonly found in builds that prioritize a compact form factor, making it ideal for tactical applications or home defense setups.
