Proof Research PXT Impact Precision 787 LA Carbon Fiber Prefit Barrel 7 PRC 22" Sendero Contour 1:8" Twist

Overview

PROOF Research PXT (Proof Exponential Twist) is a carbon fiber pre-fit barrel designed for the Impact Precision 787 long-action platform. Chambered in 7 PRC with a 22-inch Sendero contour and 1:8" twist, the barrel features rifling geometry engineered to reduce engraving force and throat erosion. This approach creates a smoother transition as the projectile engages the rifling, which can improve barrel life and consistency. These barrels are wrapped in aerospace-grade carbon fiber impregnated with a proprietary resin, offering significant weight savings compared to traditional steel barrels while providing improved heat dissipation. The PXT pre-fit barrel arrives threaded and chambered, allowing for a streamlined installation directly to the action without the need for additional gunsmithing.
