The Proof Research Carbon Fiber Sendero Barrel (brand part no. 104460) is chambered in .243 Winchester and cut to 16.5 inches in Proof’s Sendero contour, pairing a carbon-fiber-wrapped construction with Proof’s sub-MOA accuracy guarantee. This barrel carries a fast 1-7.5 twist rate to stabilize a wide range of .243 bullet weights, and it measures 2.5 inches at the breech with a 1.20-inch shank diameter for a solid fit into a compatible action. At roughly 2 pounds 8 ounces, it’s dramatically lighter than a comparable steel barrel, letting a rifle carry Proof’s accuracy without the weight penalty on a long day afield.
