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 10.5-inch barrel with a 1:7 twist rate, which stabilizes a variety of bullet weights effectively. Its carbine-length gas system ensures reliable cycling and performance, making it suitable for short-barreled applications. This upper is commonly found in compact builds that prioritize maneuverability and quick handling, such as those intended for close-quarters use.
