Building a custom .264 rifle demands a barrel that delivers both precision and reliability, and the PROOF Research Carbon Fiber Blank Bolt .264 Caliber barrel is engineered to meet those demands. This 26-inch Sendero-contour barrel combines PROOF's proven carbon fiber construction with a 1:7.5 twist rate optimized for the .264 caliber's range of projectiles. Whether you're assembling a long-range hunting rifle or a precision target build, this blank bolt configuration gives you the platform to create exactly the rifle you need.
Carbon fiber barrels have become the standard among serious shooters who want to reduce overall weight without sacrificing stiffness or accuracy. PROOF Research has built a reputation for manufacturing barrels that shoot and last, and this .264 blank doesn't compromise on either. The Sendero profile strikes a balance between handling weight and thermal stability, while the 1:7.5 twist rate provides the velocity and stabilization characteristics the .264 caliber is known for.
This is a gunsmith's component—a bare barrel ready for your action, stock, and finishing touches. The 2.5-inch breech and 1.20-inch shank diameter follow standard specifications, so it integrates with conventional bolt face actions and standard gunsmithing practices. Weighing in at 3 pounds 5 ounces, you're getting the weight savings carbon fiber delivers without the guesswork on fit or function.

This blank bolt barrel has a standard 2.5-inch breech and 1.20-inch shank diameter, compatible with conventional bolt face actions. Your gunsmith will verify fit with your specific action during assembly.
Carbon fiber barrels deliver significant weight savings compared to steel while maintaining rigidity and thermal stability. That means less recoil and fatigue during long shooting sessions, plus the stiffness carbon fiber provides helps maintain accuracy shot after shot.
No—this is a blank barrel component designed for custom gunsmith assembly. You'll need a gunsmith to install it on your action, chamber it, and finish the muzzle according to your specifications.
The 1:7.5 twist is optimized for the .264 caliber's velocity and bullet weights, providing the stabilization needed across the range of projectiles commonly used in .264 builds. Your gunsmith can confirm it matches your intended load and bullet selection.
