Proof Research built its reputation on carbon-fiber-wrapped barrels that shed heat and weight without giving up match-grade accuracy, and this PXT barrel blank brings that technology to your next custom build. The .224-caliber, 18-inch blank in a Sendero contour starts with a match-grade stainless core that is then wrapped in Proof's aerospace-grade carbon fiber, cutting significant weight compared to an all-steel barrel of similar stiffness. It is a favorite starting point for gunsmiths building lightweight precision rifles for mountain hunting or long days behind the trigger. As a blank, it will need to be chambered, threaded, and fitted by a qualified gunsmith.
