Proof Research PXT Defiance Ruckus Carbon Fiber Prefit Barrel 7 PRC 22" Sendero Contour 1:8" Twist

Overview

Proof Research PXT carbon fiber pre-fit barrels are designed for the Defiance Ruckus action in 7 PRC. These 22-inch barrels utilize Proof Exponential Twist (PXT) rifling geometry, which is engineered to reduce engraving force and minimize throat erosion. The barrels feature a Sendero contour and a 1:8-inch twist rate. Constructed with high-strength, aerospace-grade carbon fiber and a proprietary matrix resin, these barrels offer significant weight reduction compared to steel barrels of similar contour. They are chambered, threaded, and ready for installation. The carbon fiber wrap provides extreme temperature resistance and improved heat dissipation for increased barrel life.
