Overview
The Proof Research PXT PR15 AR-15 barrel is chambered in 223 Wylde with a 20-inch standard contour, a carbon fiber finish, and a 1:7" twist rate. It incorporates PROOF Exponential Twist (PXT) rifling geometry to reduce engraving force, minimize throat erosion, and provide a smoother transition as the projectile engages the bore. This next-generation barrel technology delivers match-grade accuracy, improved heat dissipation, reduced harmonic vibration, and increased durability while remaining significantly lighter than traditional steel alternatives.
