The Proof Research .264 Carbon Fiber Bolt-Action Barrel at 24 inches, Sendero contour (brand part no. 110171), gives long-range and precision shooters a lightweight option in the 6.5mm/.264-family calibers. Proof cuts this barrel to a Sendero profile with a 2.5-inch breech length and a 1.20-inch shank diameter, sized for common bolt-action receiver setups, and wraps it in carbon fiber to shed weight compared to a comparable steel barrel of the same contour. A 1:7.5 twist rate stabilizes the long, high-BC 6.5mm bullets favored in long-range and PRS-style competition. At roughly 3 pounds 2 ounces, it keeps a rifle balanced and easy to carry without sacrificing the rigidity needed for consistent accuracy at distance.
