Proof Research 100943 Bolt Action Blank 284 Cal 24 in Sendero Contour 1:8.40 in Twist 5 Grooves, Carbon Fiber Wrapped, Rifle Barrel

Overview

The Proof Research Bolt Action Blank is a 24-inch match-grade rifle barrel featuring a Sendero contour, a 1:8.40-inch twist rate, and 5-groove rifling in .284 caliber. Built with a double-stress-relieved 416R stainless steel core, the barrel is wrapped in high-strength, aerospace-grade carbon fiber using a proprietary matrix resin helical wrapping pattern. This carbon fiber construction makes the barrel up to 64% lighter than traditional steel barrels of a similar contour while significantly improving thermal diffusivity and heat dissipation. The design minimizes harmonic vibration, prevents point-of-impact shift during high-volume fire, and delivers exceptional durability and accuracy.
