Proof Research PXT Defiance Ruckus Prefit Barrel 6mm Creedmoor 26" Stainless Competition Contour 1:7.5" Twist

Overview

The PROOF Research PXT pre-fit barrel combines carbon fiber technology with proprietary Exponential Twist rifling geometry. Designed for Defiance Ruckus actions, this 6mm Creedmoor barrel features a 26-inch stainless steel core wrapped in high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin, offering extreme temperature resistance, superior heat dissipation, and a weight up to 64% lighter than traditional steel contours. The PXT rifling progression reduces engraving force and smooths projectile engagement to minimize throat erosion, yielding a 30-to-100% increase in barrel life while maintaining match-grade accuracy and mitigating felt torque. Arriving fully chambered, threaded, and equipped with a 1:7.5" twist in a competition contour, it allows for a streamlined installation directly to the action.
