Proof Research

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 Researchs 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 Proofs advanced composites division PROOF Research ACD.
