Proof Research PXT Carbon Fiber Bolt Action Barrel Blank 284 Cal 22" 1:8 Twist Sendero Profile

The Proof Research PXT Carbon Fiber Barrel Blank is engineered for bolt-action rifles in .284 caliber with a 22-inch length, 1:8 twist rate, and Sendero contour profile. PXT (PROOF Exponential Twist) technology features a next-generation rifling geometry designed to reduce engraving force, minimize throat erosion, and improve ballistic performance. The carbon fiber wrapped construction delivers exceptional rigidity and heat dissipation while significantly reducing weight compared to traditional steel barrels.
