Proof Research

Lightweight Up to 64% lighter than traditional steel barrels of similar contour.Extreme Temperature ResistanceImproved heat dissipation for cooler and longer lasting barrels. Unprecedented DurabilityWrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin.

Contour Weights: 7lbs-12oz = Competition6lbs-11oz = M246lbs-5oz = Heavy Palma5lbs-8oz = Medium Palma3lbs-11oz = Medium SporterNote: The weight is before the 2" sacrificial piece on the front of the barrel in removed and before chamber and threading.When Proof joined with Lawrence Barrels in 2012 we acquired 15 years of experience in manufacturing precision steel rifle barrels. Proof makes their stainless steel barrels in-house with an absolute commitment to extreme accuracy and quality....
