Proof Research PXT Tikka T3X Carbon Fiber Prefit Barrel 7mm Backcountry 16.5" Sendero Contour 1:8" Twist

Overview

The Proof Research PXT Tikka T3X Carbon Fiber Prefit Barrel is a 16.5-inch 7mm Backcountry barrel featuring a Sendero contour and a 1:8" twist. It integrates PROOF Exponential Twist (PXT) rifling geometry and twist progression, which reduces engraving force, minimizes throat erosion, and smooths projectile engagement to enhance consistency, extend barrel life, and lower felt torque for better recoil control. Wrapped in high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin, this pre-fit barrel offers up to a 64% weight reduction compared to traditional steel barrels of similar contour. It provides extreme temperature resistance and improved heat dissipation for longer-lasting performance. Threaded and chambered, the barrel is ready to shoulder directly to the action without additional machining.
