Product Info for Proof Research PXT Defiance Ruckus.223 Remington Threaded Rifle Barrel

PROOF Research pre-fit carbon fiber & steel barrels for the Defiance Ruckus are to be installed in a simple operation requiring few specialized tools. Pre-fit barrels are chambered and threaded for a simple install that require only a few specialized tools. Simply torque your barrel on, double check headspace with proper gauges and head to the range! Unprecedented accuracy and performance - it does not get much better than Defiance Ruckus carbon fiber & steel pre-fit barrels. PROOF Research 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.image
