Proof Research PXT Zermatt Origin Carbon Fiber Prefit Barrel 6.5 Creedmoor 20" Sendero Contour 1:7.5" Twist

Overview

The Proof Research PXT Zermatt Origin Carbon Fiber Prefit Barrel is chambered in 6.5 Creedmoor with a 20-inch barrel length, a Sendero contour, and a 1:7.5" twist. Featuring PROOF Exponential Twist (PXT) rifling geometry, this carbon fiber barrel is engineered to reduce engraving force, minimize throat erosion, and provide a smoother transition as projectiles engage the bore, resulting in extended barrel life, improved consistency, and reduced felt torque. Pre-fit barrels arrive threaded, chambered, and ready to shoulder directly to the action without additional machining. They are up to 64% lighter than traditional steel barrels of similar contour, offer extreme temperature resistance for improved heat dissipation, and feature a high-strength, aerospace-grade carbon fiber wrap impregnated with a proprietary matrix resin.
