Proof Research Blaser 264 Carbon Fiber Blank Barrel

The Proof Research Blaser 264 is a carbon fiber barrel blank that comes ready for a gunsmith to chamber and fit your action. It is extremely lightweight, up to 64% lighter than traditional steel barrels of similar contours. The barrels feature improved heat dissipation for cooler and longer lasting barrels, and are wrapped with high strength, aerospace grade carbon fiber impregnated with a proprietary matrix resin. The Blaser barrels are available in several calibers, lengths and twist rates.

Chambered for .264 Winchester Magnum (often abbreviated “.264 Win Mag”), this barrel blank pairs a precision steel bore with a carbon fiber wrap, which reduces overall weight, increases rigidity, and aids in heat control compared with an all-steel barrel. As a blank barrel, it arrives unchambered and unthreaded, leaving those final steps to a qualified gunsmith who will bore, thread, and chamber it to match the specific Blaser action and desired specifications. Because it’s designed around a Blaser profile, once finished it should integrate smoothly with compatible Blaser receivers.

Shooters choose a Proof Research Blaser 264 carbon fiber barrel blank like this when they want the ballistic performance of the Proof Research Blaser .264 Winchester Magnum—known for high velocity and effective long-range capability—combined with the weight savings and thermal advantages of carbon fiber wrapping. This makes it appealing for custom long-range rifles, mountain hunting rifles, or other precision applications where managing weight and achieving consistent accuracy are key goals. Overall, the Proof Research Blaser .264 carbon fiber blank barrel offers a high-end foundation for a tailored, performance-oriented rifle build.
