Overview
The Proof Research Carbon Fiber Barrel Blank is a 22-inch barrel featuring a .308 caliber, 1:9 twist rate, and a Sendero contour. Constructed in-house from double-stress relieved 416R stainless steel, the steel core is cut rifled, lapped, and borescope-inspected for match-grade consistency. It is wrapped in aerospace-grade carbon fiber utilizing a helical wrapping pattern that improves longitudinal thermal diffusivity to efficiently dissipate heat, reduce cooling times, and maintain accuracy during high-volume strings of fire.
