Product Overview
PXT AR Barrels
PROOF Research PXT carbon fiber barrel blanks combine next-generation rifling technology with the lightweight performance and precision that have defined PROOF barrels for years. 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 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. These 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.
Available in both PROOF carbon fiber and traditional steel configurations; PXT AR barrels deliver lightweight handling; precision performance; and next-generation barrel technology across a wide range of modern gas gun applications.
