The PROOF Research BBL CF Blank Bolt barrel in .264 caliber gives you a precision rifle-building foundation that's built for accuracy without the weight penalty. This 18-inch Sendero Light profile barrel pairs modern carbon-fiber construction with a 1-7.5 twist rate engineered for the .264 cartridge family—whether you're running the 6.5 Creedmoor, 6.5 PRC, or another .264 round. At just 2 lbs 7 oz, it delivers the stiffness you need for consistent groups while keeping your rifle's overall heft reasonable for field carry and repeated shooting sessions.

PROOF Research barrels are known in the precision shooting world for holding tight tolerances and repeatable accuracy. The Sendero Light contour is a classic choice: it tapers intelligently from a 1.20-inch shank at the breech to keep barrel harmonics predictable and rigid where it counts most. With a 2.5-inch breech diameter, this blank integrates seamlessly into standard rifle builds and offers the flexibility to profile and thread it to your exact specifications.

This is a blank bolt barrel—no crown, no thread, no gas port—so you'll need a competent gunsmith to finish it to your intended action and muzzle device. That hands-on approach means you own the final product from the ground up, and you get a barrel that's genuinely tailored to your build instead of a compromise off-the-shelf item. If you're building a long-range hunting rifle, a precision target rifle, or a backcountry stalking setup where every ounce matters, a quality blank like this from PROOF Research is the smart starting point.
