The Proof Research 264 Caliber 4-Groove Twist Carbon Fiber Barrel Blank is purpose-built for gunsmithing custom bolt-action rifles in .264 caliber. If you're building a long-range hunting rig or precision target rifle and want to shed weight without sacrificing accuracy or durability, this is the blank your gunsmith needs to start with. Proof Research has engineered these carbon fiber barrels to deliver match-grade accuracy while keeping your rifle substantially lighter than a traditional steel barrel would allow—we're talking up to 64% weight reduction depending on your configuration.
Carbon fiber construction offers genuine advantages that go beyond the scale. The material is significantly stronger than steel on a weight-for-weight basis, resists cosmetic damage from normal field use and storage, and manages heat differently than steel. That improved heat dissipation means your barrel runs cooler during high-volume shooting sessions, which supports both longevity and consistency. You won't see point-of-impact shift when you're running strings of fire—the reduced harmonic vibration that carbon fiber delivers keeps your groups tight and predictable.
This is a blank, ready for your gunsmith to thread and chamber to your specifications. Whether you're building a mountain hunting rifle where ounces matter or a precision .264 magnum for extended-range work, starting with a Proof Research carbon blank gives you a foundation that balances performance with real-world practicality.
