PROOF Research PXT Steel Competition Contour Barrel Blanks

NOTE: Barrel blanks are not chambered or threaded. They will require proper fitting by a gunsmith to your action. Due to the nature of PXT, these barrels are meant for 26″ finish length. You CANNOT cut down these barrels from the muzzle end, there is a groove in the blank that notes exactly where your crown should be. If you MUST cut them down, you can remove up to 3″ from the breech end.

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.

In controlled testing, PXT barrels have demonstrated significant increases in barrel life while maintaining the accuracy standards expected from a PROOF barrel.
