The Proof Research PR-15 is a premium match-grade AR-15 barrel chambered in 6mm ARC, featuring a 14.5-inch length and a fast 1:7.5 twist rate optimized for stabilizing long, high-BC 6mm projectiles. Constructed with Proof Research's carbon fiber-wrapped technology and polygonal rifling (PXT), this barrel delivers exceptional accuracy, reduced weight, and superior heat dissipation compared to traditional steel barrels.
