Proof Research PXT Tikka T3X Carbon Fiber Prefit Barrel 6.5 PRC 22" Sendero Contour 1:7.5" Twist

Overview

The Proof Research PXT Tikka T3X Carbon Fiber Prefit Barrel is a 22-inch Sendero contour barrel chambered in 6.5 PRC with a 1:7.5 twist rate. Utilizing next-generation PROOF Exponential Twist (PXT) rifling geometry, this barrel is engineered to reduce engraving force, minimize throat erosion, and create a smoother transition as the projectile engages the bore, resulting in reduced felt torque, improved recoil control, and up to a 30-100% increase in barrel life. Wrapped in high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin over a match-grade steel liner, the PXT barrel offers extreme temperature resistance for superior heat dissipation, and is up to 64% lighter than traditional steel barrels of a similar contour. It arrives threaded, chambered, and ready to shoulder directly onto compatible actions without additional machining.
