The Proof Research Carbon Fiber Sendero Barrel (brand part number 110157) is a chambered and finished 24-inch .308 Winchester barrel in the Sendero contour, wrapped in carbon fiber over a steel core by Proof Research. Unlike an unchambered blank, this barrel arrives finished, carrying a 1:9 twist rate, a 2.5-inch breech length, and a 1.20-inch shank diameter, weighing approximately 2 pounds, 13 ounces. It gives .308 Winchester shooters real weight savings over a comparable steel barrel without sacrificing match-grade accuracy.
