The Proof Research 264 Caliber 1-8 Twist 24" Carbon Fiber Bull Barrel is built for shooters who demand consistent precision from a bolt-action platform. Starting with a match-grade 416R stainless steel core that is turned down to a reduced profile, Proof wraps the barrel in aerospace-grade carbon fiber to deliver a rigid, lightweight bull contour that resists heat and maintains accuracy over extended strings of fire.

This 24-inch, 1-8 twist barrel is optimized for .264/6.5 mm cartridges, offering excellent bullet stabilization and velocity for long-range target shooting and hunting. The carbon fiber construction promotes rapid heat dissipation and minimizes harmonic vibration, helping the barrel stay cooler and track true shot after shot. It is an ideal upgrade for precision rifle builds where reduced weight and repeatable accuracy matter, backed by Proof Research’s reputation for advanced composites and meticulous barrel craftsmanship.
