Proof Research 100950 Bolt Action Blank 284 Win 26 in Black Carbon Fiber Finish 416R Stainless Steel Material Blank with Sendero Contour for s, Rifle Barrel

Overview

The Proof Research 284 Win bolt action barrel blank features a 26-inch length and a 1:8 twist rate. Constructed from 416R stainless steel, the barrel is wrapped in aerospace-grade carbon fiber using a proprietary matrix resin. This design makes the barrel up to 64% lighter than traditional steel barrels of a similar contour while providing superior heat dissipation, reduced harmonic vibration, and enhanced structural damping. This match-grade blank features a Sendero profile and is engineered to maintain accuracy through sustained fire strings. It is intended for professional gunsmithing, as the blank must be threaded and chambered for a specific action before use.
