Proof Research 264 Win Mag 20" 1:7.5 Twist Carbon Fiber Sendero Light Bolt Action Barrel Blank

The Proof Research Bolt Action Barrel Blank is a precision 264 Win Mag blank engineered for custom rifle builders seeking match-grade performance in a lightweight Sendero Light contour. This blank features a 20" 416R stainless steel bore wrapped in Proof Research's signature carbon fiber jacket, trimming weight and improving barrel harmonics and cooling compared to a conventional steel contour of the same length.

Cut with a 1:7.5 twist rate to stabilize the full range of modern 264 Win Mag (6.5mm) projectiles, the blank carries a 1.20" shank diameter and a 2.5" breech length for broad compatibility with popular precision bolt-action actions. The Sendero Light profile keeps the finished barrel at roughly 2 lbs 14 oz, striking a balance between the rigidity needed for long-range accuracy and the light carry weight desirable for a mountain or backcountry hunting build.

Whether you are building a lightweight mountain hunting rifle, a long-range target rig, or a hard-hitting plains-game setup, this Proof Research Sendero Light blank delivers the accuracy and weight savings that have made Proof Research the benchmark for premium custom rifle components. New from Proof Research and ready for your custom build.
