PROOF Research pre-fit carbon & steel barrels for Zermatt Arms TL3/SR3 and Origin actions make it easy to upgrade your rifle or change calibers. 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.
DISCLAIMER:
* All shouldered pre-fit barrels are guaranteed for headspacing.
* Due to variance in actions we do not guarantee the timing and alignment of the barrel engraving to your stock line.
* Barrels are specific to the action type/length and are not interchangeable.
