Proof Research PXT Falkor 7EVEN/MT7 Carbon Fiber Prefit Barrel 6.5 PRC 20" Sendero Contour 1:7.5" Twist

Overview

The Proof Research PXT (Proof Exponential Twist) Falkor 7EVEN/MT7 carbon fiber pre-fit barrel is chambered in 6.5 PRC with a 20-inch length and a 1:7.5" twist rate. The PXT rifling geometry is designed to minimize throat erosion and reduce engraving force, providing a smoother transition for the projectile into the bore. This technology contributes to improved consistency and increased barrel life, with testing demonstrating 30-100% longevity improvements over conventional rifling. Constructed with high-strength, aerospace-grade carbon fiber and a proprietary resin matrix, the barrel is designed for superior heat dissipation and weight reduction, weighing up to 64% less than equivalent steel contours. The pre-fit design is ready for shoulder-fit installation onto compatible actions, eliminating the requirement for additional machining while maintaining premium accuracy standards.
