Overview
The PSA AR-15 Upper is a complete upper receiver featuring a 16-inch barrel chambered in 5.56 NATO, designed with a mid-length gas system that enhances reliability and reduces recoil. The 1:7 twist rate is optimal for stabilizing a variety of bullet weights, making it versatile for different shooting applications. This upper commonly appears in builds that prioritize the mid-length gas system and 5.56 NATO caliber, appealing to builders looking for a balanced setup for general use or training.
