Proof Research PXT PR-15 223 Wylde 16" Carbon Fiber Intermediate Rifle Barrel

The Proof Research PXT PR-15 barrel combines advanced PXT (Proof Exponential Twist) rifling technology with a carbon fiber wrapped construction for the AR-15 platform. The PXT system features a progressive twist rate designed to reduce engraving force, minimize throat erosion, and create a smoother projectile-to-rifling transition compared to conventional barrel designs. Chambered in 223 Wylde with a 16" intermediate-length carbon fiber barrel, this drop-in upgrade delivers exceptional precision and reduced weight for AR-15 builds.
