Proof Research 130452 264 Win Mag 16.5" 1:7.5 Twist Bolt Action Barrel Blank

The Proof Research 130452 is a precision bolt action barrel blank chambered in 264 Winchester Magnum. Cut to a compact 16.5" finished length with a 1:7.5 twist, this Proof Research blank provides a solid foundation for custom bolt action rifle builds and barrel replacements in the 264 Win Mag chambering.

The 1:7.5 rifling twist stabilizes a broad range of 264 Win Mag bullet weights, from lighter projectiles through heavier match and hunting bullets. The bolt action profile is intended to be fitted to a compatible bolt action receiver, giving the builder flexibility to configure the action, stock, and overall rifle package to match the intended application.

This aftermarket barrel blank is sold as a single component for gunsmith installation or custom build use. Mounting hardware, action, muzzle device, and other build components are not included and must be sourced separately.
