Proof Research PR15 PXT Carbon Fiber Barrel 223 Wylde 14.5" 1:7 Twist

The Proof Research PR15 PXT (PROOF Exponential Twist) carbon fiber barrel in 223 Wylde represents an advanced evolution in AR-15 barrel technology. Featuring a 14.5" barrel length with a 1:7 twist rate, the PXT rifling design uses progressive twist geometry engineered to reduce engraving force, minimize throat erosion, and maximize accuracy and velocity. Compatible with AR-15/M4 pattern rifles. Built with Proof Research's signature carbon fiber construction for reduced weight without sacrificing precision.
