Overview
The PSA AR-15 16" Midlength Upper Receiver is a complete assembly designed for the AR-15 platform, featuring a 16-inch barrel chambered in 5.56 NATO. Its mid-length gas system provides a smoother cycling action, which can enhance reliability and reduce felt recoil, while the 1:7 twist rate allows for optimal stabilization of a wide range of bullet weights. This upper is a solid choice for builders looking to create versatile setups, whether for tactical applications or recreational shooting.
