Proof Research PXT Impact Precision 787 LA Carbon Fiber Prefit Barrel 300 PRC 20" Sendero Contour 1:9" Twist

Overview

The Proof Research PXT Impact Precision 787 LA prefit barrel in .300 PRC features a 20-inch carbon fiber construction with a Sendero contour and a 1:9-inch twist rate. Utilizing PXT (Proof Exponential Twist) technology, this barrel employs advanced rifling geometry to reduce engraving force and minimize throat erosion, creating a smoother transition for the projectile. This barrel is up to 64% lighter than traditional steel barrels of a similar contour and offers improved heat dissipation for consistent performance during long strings of fire. The barrel is wrapped in aerospace-grade, high-strength carbon fiber impregnated with a proprietary matrix resin. As a prefit barrel, it arrives threaded and chambered, allowing for a straightforward installation to the action without the need for additional machining.
