Up to 64% lighter than traditional steel barrels of similar contour – Match-grade accuracy – Improved heat dissipation for cooler and longer lasting barrels – No point-of-impact shift during high-volume fire – Reduced harmonic barrel vibration – Unprecedented durability – 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.
