Proof Research PXT Defiance Ruckus Carbon Fiber Prefit Barrel 6mm ARC 20" Sendero Contour 1:7.5" Twist

Overview

The Proof Research PXT Defiance Ruckus prefit barrel is a 20-inch carbon fiber Sendero-contour barrel chambered in 6mm ARC. It utilizes Proof Exponential Twist (PXT) rifling geometry to minimize throat erosion and create a smoother transition for the projectile as it engages the rifling, which aids in improving barrel life and consistency. This barrel features a 1:7.5" twist rate and is designed to shoulder directly to a Defiance Ruckus action without the need for additional machining. The barrel is wrapped in high-strength, aerospace-grade carbon fiber with a proprietary matrix resin, offering high temperature resistance and significant weight reduction compared to traditional steel barrels of a similar contour.
