The Proof Research PXT Carbon Fiber Barrel is a premium bolt action barrel blank featuring the innovative PROOF Exponential Twist (PXT) rifling technology. PXT rethinks conventional rifling geometry and twist progression to reduce engraving force, minimize throat erosion, and smooth projectile engagement with the rifling. Built in a Sendero Light contour, this 20" barrel is chambered in 264 caliber and wrapped in a lightweight carbon fiber sleeve for superior stiffness-to-weight ratio and consistent performance.
