Proof Research’s Carbon Fiber Barrel manufacturing process begins with full-profile, match-grade 416R stainless steel barrel blanks that 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 Proof’s advanced composites division, PROOF Research ACD.
