Proof Research 105467 Bolt Action Barrel Blank 264 Cal 1:8 Twist 16.50, Sendero Contour Carbon Fiber Wrapped, Rifle Barrel

Overview

The Proof Research bolt-action barrel blank is precision-engineered for match-grade accuracy and durability. Produced from double-stress-relieved 416R stainless steel, the core is wrapped in high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin. This helical wrapping pattern significantly improves thermal diffusivity, allowing the barrel to dissipate heat faster and maintain consistent accuracy over long strings of fire. The blank features a 264 caliber bore, a 1:8 twist rate, a 16.50-inch length, and a Sendero contour, arriving ready for threading and chambering by a gunsmith.
