PROOF BBL BOLT PXT 224 22 CF SENDERO 1-8

PROOF Research PXT carbon fiber barrel blanks combine next-generation rifling technology with the lightweight performance and precision that have defined PROOF barrels for years. PXT- PROOF Exponential Twist- is a complete rethinking of conventional rifling geometry and twist progression engineered to reduce engraving force minimize throat erosion and create a smoother transition as the projectile engages the rifling. – By dramatically reducing rifling lead angle and smoothing projectile engagement into the bore PXT technology helps reduce wear improve consistency and create less felt torque during firing for improved recoil control and the ability to stay on target more effectively. – In controlled testing PXT barrels have demonstrated 30-100% increase in barrel life while maintaining the accuracy standards expected from a PROOF barrel. – Built around our proven carbon fiber construction PXT barrel blanks provide exceptional stiffness-to-weight ratio and reduced overall rifle weight without sacrificing performance. Designed for custom rifle builders and gunsmiths these blanks offer a premium foundation for lightweight hunting rifles precision long-range systems and modern high-performance rifle builds where consistency and durability matter most. – Barrel Length in Inches 22 – Twist Rate 8 PXT – Barrel Breech 2.5 – Shank Diameter 1.20 – Contour Sendero – Weight 3lbs-2oz
