Proof Research PXT Zermatt TLS/SR3 Carbon Fiber Prefit Barrel 22 Creedmoor 22" Sendero Contour 1:8" Twist

Overview

The Proof Research PXT Zermatt TLS/SR3 Carbon Fiber Prefit Barrel is a 22-inch match-grade barrel with a Sendero contour and a 1:8-inch twist rate, chambered in 22 Creedmoor. It utilizes PXT (PROOF Exponential Twist) rifling geometry, which is engineered to reduce engraving force, minimize throat erosion, and smooth projectile engagement into the bore for improved consistency, reduced felt torque, and up to a 30-100% increase in barrel life. Wrapped in high-strength, aerospace-grade carbon fiber infused with a proprietary matrix resin, the barrel is up to 64% lighter than traditional steel alternatives while providing exceptional heat dissipation and durability. Supplied threaded and chambered as a pre-fit, it shoulders directly onto the action without requiring additional machining.
