Frequently Asked Questions

Will this barrel work with my current bolt action?

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.

What's the advantage of carbon fiber for a .264 barrel?

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.

Is this a finished, ready-to-shoot barrel?

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.

Why the 1:7.5 twist rate?

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.
