Proof Research PXT Falkor 7EVEN/MT7 Carbon Fiber Prefit Barrel 6.5 Creedmoor 22" Sendero Contour 1:7.5" Twist

Overview

The Proof Research PXT (Proof Exponential Twist) Falkor 7EVEN/MT7 carbon fiber pre-fit barrel is chambered in 6.5 Creedmoor with a 22-inch length and a 1:7.5" twist rate. PXT technology utilizes an optimized rifling geometry and twist progression designed to reduce engraving force and throat erosion. This advancement results in smoother projectile engagement, reduced felt torque, and an increase in barrel life of 30-100% during controlled testing. These barrels are wrapped in high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin, which provides extreme temperature resistance and heat dissipation. The barrel is up to 64% lighter than traditional steel barrels of a similar contour. Arriving threaded and chambered, the PXT pre-fit allows for direct installation to the action without the need for additional gunsmithing.
