Proof Research PXT Defiance Ruckus Carbon Fiber Prefit Barrel 22 Creedmoor 18" Sendero Contour 1:8" Twist

Overview

The Proof Research PXT Defiance Ruckus Carbon Fiber Prefit Barrel is chambered in 22 Creedmoor with an 18-inch barrel length, a Sendero contour, and a 1:8" twist rate. Featuring a carbon fiber finish, it is threaded, chambered, and ready to shoulder directly to the action without additional machining. PROOF Research PXT (Exponential Twist) barrels incorporate a complete rethinking of conventional rifling geometry and twist progression to reduce engraving force, minimize throat erosion, and create a smoother projectile engagement transition. This proprietary design delivers enhanced barrel life, reduced felt torque during firing, and improved recoil control while maintaining strict accuracy standards. Wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin, the barrel provides extreme temperature resistance, superior heat dissipation, and a lightweight profile up to 64% lighter than traditional steel barrels of similar contour.
