Proof Research PXT AR Platform 6mm ARC Threaded AR Barrel 1.15oz 7.5 Twist Gas Length Rifle+1 18 in Carbon Black

Proof Research PXT AR Platform 6mm ARC Threaded AR Barrel 1.15oz 7.5 Twist Gas Length Rifle+1 18 in Carbon Black. PXT - PROOF Exponential Twist - is a complete rethinking of conventional rifling design 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 recoil control and the ability to stay on target more effectively. In controlled testing PXT barrels have demonstrated significant increases in barrel life while maintaining the accuracy standards expected from a PROOF barrel. PXT AR barrels arrive fully chambered and ready for installation making them an easy upgrade for shooters looking to build or refine a high-performance rifle system.
