The Proof Research 100998 Carbon Fiber Bolt Action Barrel Blank in .308 Winchester is built for precision rifle projects where weight savings and consistency matter. This 22.00" Sendero contour barrel uses a carbon fiber over stainless steel core to deliver a stiff, accurate platform while significantly reducing front-end weight compared to traditional steel barrels.
With a 1:10 twist rate, 2.5" breech length, and 1.20" shank diameter, this blank arrives ready for your gunsmith to chamber and thread to your preferred .308 configuration. Its balanced Sendero profile and approximate 2.8 lb weight make it well suited for hunting rifles and accuracy-focused range builds where you want easy carry without giving up stability. Proof Research’s advanced materials and meticulous manufacturing have earned a strong reputation among discerning shooters who demand repeatable performance.
