Overview
The PSA 10.5" Carbine-Length 5.56 NATO Upper Receiver is a complete assembly designed specifically for AR-15 platforms, featuring a compact 10.5-inch barrel that lends itself to maneuverability while retaining the capability of the 5.56 NATO caliber. With a pistol-length gas system and a 1:7 twist rate, this upper is optimized for stability and accuracy, allowing for a variety of bullet weights to perform well. This upper receiver is commonly found in builds that emphasize a shorter, more tactical profile, making it suitable for close-quarters engagements or compact setups.
