The Proof Research .224 Carbon Fiber Bolt-Action Barrel at 22 inches, Sendero contour (brand part no. 103494), gives varmint and predator hunters a lightweight, accurate option in the popular .224-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. A 1:8 twist rate stabilizes a wide range of .224-caliber bullet weights, from lighter varmint loads to heavier long-range options. At roughly 3 pounds 2 ounces, it keeps a rifle nimble in the field without sacrificing the rigidity needed for consistent accuracy.
