Proof Research 264 Winchester Magnum 24 Inch Bolt Action Rifle Barrel

Proof Research barrels represent an uncompromising commitment to precision engineering. The Carbon Fiber barrel begins with a full-profile, match-grade 416R stainless steel barrel blank manufactured in Proof Research’s firearms division. The blank is then turned down to a significantly reduced profile, substantially lowering overall weight. This contoured barrel is subsequently wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin developed by PROOF Research’s advanced composites division, PROOF Research ACD. The carbon fiber construction provides exceptional heat diffusion and thermal transport through the barrel wall, enabling superior heat management. The result is an aerospace-grade, high-fiber content composite barrel that delivers strength and light weight while maintaining accuracy comparable to precision steel barrels and durability for demanding field conditions. This 24 inch barrel is designed for bolt action rifles chambered in .264 Winchester Magnum.
