The Proof Research Carbon Fiber Sendero Light Barrel Blank (brand part number 105351) is a 24-inch .264 Winchester Magnum barrel blank finished in black, wrapped in aerospace-grade carbon fiber over a 416R stainless steel core. Machined by Proof Research with a 1:8 twist rate in the lightweight Sendero Light contour, this blank runs up to 64% lighter than a traditional steel barrel of similar contour while improving heat dissipation and resisting point-of-impact shift during high-volume fire. As a blank, it is sold unchambered for a gunsmith to fit and finish to a specific action.
