Proof Research 105337 Bolt Action Blank 264 Cal 24 in Sendero Light Contour 1:7.50 in Twist 4 Grooves, Carbon Fiber Wrapped, Rifle Barrel

Overview

The Proof Research .264 Cal bolt-action barrel blank is a high-performance, match-grade barrel designed for custom rifle builds. It features a 24-inch length with a 1:7.50-inch twist rate and 4-groove rifling. The barrel utilizes a Sendero Light contour and is constructed with a 416R stainless steel liner wrapped in high-strength, aerospace-grade carbon fiber and a proprietary resin matrix. This construction significantly reduces weight compared to traditional steel barrels while improving heat dissipation, reducing harmonic vibration, and preventing point-of-impact shift during high-volume fire. It has a 2.5-inch breech length and a 1.2-inch shank diameter. Note: This is an unchambered barrel blank that requires finishing, threading, and chambering by a professional gunsmith before use.
