Product Info for Proof Research PXT Tikka Carbon Pre-Fit .300 Winchester Magnum Threaded Rifle Barrel

ROOF Research pre-fit carbon fiber and Steel barrels for Tikka actions make it easy to upgrade your current rifle. Simply torque on, double check & ensure headspace with proper gauges, and head to the range! PXT pre-fit barrels combine next-generation rifling technology with the simplicity and convenience of a ready-to-install barrel system. PXT - PROOF Exponential Twist - is a complete rethinking of conventional rifling geometry and twist progression, engineered to reduce engraving force, minimize throat erosion, and create a smoother transition as the projectile engages the rifling. By dramatically reducing rifling lead angle and smoothing projectile engagement into the bore, PXT technology helps reduce wear, improve consistency, and create less felt torque during firing for improved shooting control and the ability to stay on target more effectively.
