The Proof Research Bolt Action Barrel in .264 Winchester Magnum (brand part number 100912) wraps a reduced-profile 416R stainless steel core in aerospace-grade carbon fiber, the same construction Proof uses across its precision rifle barrel lineup. Turning the steel core down to a lighter profile before wrapping it in carbon fiber sheds significant weight compared to a full-profile steel barrel of the same contour, while the carbon wrap diffuses and transports heat effectively to keep the barrel running cooler through longer strings of fire. The result is an aerospace-grade composite barrel that holds match-grade accuracy while standing up to demanding field and range conditions. This 24-inch bolt-action barrel is finished in black and cut for the .264 Winchester Magnum cartridge.
