Description
The Proof Research Bolt Action Barrel Blank in .264 Winchester Magnum is a precision match-grade blank engineered for custom rifle builders seeking top-tier accuracy without the heft of a traditional all-steel barrel. This 105351 blank features a 24-inch 416R stainless steel core wrapped in a high-modulus carbon fiber sleeve, finished in Proof’s signature black carbon fiber texture.
Cut on the Sendero Light contour with a 1:8-inch twist rate, this barrel is well-suited to the full range of .264 Win Mag bullet weights, from lighter varmint projectiles through heavy 140+ grain match and hunting bullets. The Sendero Light profile keeps weight around 2 lbs 15 oz while retaining the stiffness needed for consistent accuracy, and the 1.20-inch shank diameter with a 2.5-inch breech length gives your gunsmith a solid foundation for fitting to a standard bolt action action. The carbon fiber wrap delivers up to 64% weight savings versus a comparable all-steel barrel of the same contour.
As a true barrel blank, this unit ships un-chambered so your gunsmith can cut the chamber, finish the tenon, and crown the muzzle to your specific action and chosen muzzle device. No sights are included; the blank is intended for a custom build with the optic or iron sight arrangement of the builder’s choice. Proudly manufactured in the USA by Proof Research.
