Proof Research Blaser 338 Carbon Fiber Blank Barrel

The Proof Research Blaser 338 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.

Carbon fiber has long been hailed across many industries—aerospace, cycling, alternative energy—as a wonder material making everything lighter and stronger. When employed in a rifle barrel the benefits extend beyond reducing weight and increasing strength. Our patented manufacturing process begins with full-profile, match-grade 416R stainless steel barrel blanks that are made in our firearms division.

These blanks are then turned down to a significantly reduced profile greatly reducing weight. This reduced contour barrel is then wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin developed by our advanced composites division, PROOF Research ACD. The carbon fibers we use have a unique ability to diffuse heat along the length of the barrel (much like fiber optics transmit light).
