Proof Research 264 Winchester Magnum 26 Inch Bolt Action Rifle Barrel

Proof Research barrels represent an uncompromising commitment to performance and precision. The Carbon Fiber barrel starts with a full-profile, match-grade 416R stainless steel barrel blank manufactured in Proof’s firearms division. The blank is then turned down to a substantially reduced profile, significantly cutting weight without compromising strength. This contoured steel core is wrapped in high-strength, aerospace-grade carbon fiber that is impregnated with a proprietary matrix resin developed by Proof Research’s advanced composites division, PROOF Research ACD. The carbon fiber construction diffuses heat effectively and transports it efficiently through the barrel wall, dramatically improving thermal management. The result is an aerospace-grade composite barrel that delivers the accuracy of precision steel while being stronger and lighter, with the durability to withstand the most demanding shooting environments. This 26″ barrel is designed for bolt action 264 Winchester Magnum rifles.
