Proof Research PXT Tikka T3X Carbon Fiber Prefit Barrel 6.5 Creedmoor 18" Sendero Contour 1:7.5" Twist

Overview

The Proof Research PXT Tikka T3X carbon fiber prefit barrel is an 18-inch barrel chambered in 6.5 Creedmoor with a 1:7.5 twist rate and a Sendero contour. Utilizing PROOF Exponential Twist (PXT) rifling geometry, it is engineered to reduce engraving force, minimize throat erosion, and smooth projectile engagement for increased barrel life and improved recoil control. Wrapped in high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin over a steel core, this prefit barrel delivers extreme temperature resistance, efficient heat dissipation, and a lightweight profile that shoulders directly onto the action without additional machining.
