Proof Research PXT Carbon Fiber Bolt Action Barrel Blank 284 Cal 20" 1:8 Twist Sendero Profile

The Proof Research PXT Carbon Fiber Barrel Blank is engineered for bolt-action rifles chambered in .284 caliber, featuring a 20-inch Sendero contour profile with a 1:8 twist rate. Built with Proof Research's PXT (Proof Exponential Twist) rifling technology, this barrel blank is designed to reduce engraving force, minimize throat erosion, and improve long-range precision. The carbon fiber construction delivers exceptional rigidity and heat dissipation at a significantly reduced weight compared to traditional steel barrels.
