The Proof Research Sendero Light Carbon Fiber Barrel (brand part no. 105290) is a 20-inch bolt-action barrel chambered around .264 caliber, built with Proof’s carbon-fiber-wrapped construction to shave weight off a precision rifle without sacrificing barrel stiffness. A 1-in-8 twist rate stabilizes the longer, heavier-for-caliber bullets 6.5mm shooters favor for extended-range work, and a 2.5-inch breech length with a 1.20-inch shank diameter are machined to fit standard bolt-action receiver specs. At roughly 2 pounds 10 ounces, it is dramatically lighter than an equivalent steel barrel of the same length and contour, making it a popular upgrade for backcountry hunting rifles and long-range bolt guns alike.
