Overview
The PSA 11.5" 5.56 NATO Upper is a complete upper receiver designed for AR-15 builds, featuring an 11.5-inch barrel with a 1:7 twist rate, which stabilizes a wide range of bullet weights effectively. This upper utilizes a carbine-length gas system, promoting reliable cycling and performance, especially in short-barreled configurations. You'll typically find this upper in builds focused on maneuverability and versatility, particularly in close-quarters settings.
