Proof Research PXT Carbon Fiber Bolt Action Barrel Blank .264 Cal 22" Sendero Light Profile

The Proof Research PXT Carbon Fiber Barrel Blank in .264 caliber features a 22" Sendero Light contour designed for bolt-action rifles. PXT (Proof Exponential Twist) technology rethinks conventional rifling geometry with a progressive twist rate engineered to reduce engraving force, minimize throat erosion, and create a smoother projectile-to-rifling transition. The carbon fiber construction delivers exceptional rigidity and lightweight performance without sacrificing precision or barrel life.
