PROOF RESEARCH, INC AR-15 Parts & Accessories

Proof Research is an American manufacturer of precision rifle barrels, carbon-fiber wrapped barrels, and complete rifles, headquartered in Columbia Falls, Montana. The brand pioneered the widely adopted carbon-fiber-wrapped barrel, which combines a thin steel liner with a cross-wound carbon fiber sleeve to deliver lighter weight without sacrificing stiffness or accuracy. Proof Research barrels are widely used by precision rifle competitors, long-range hunters, and military users. The company also produces complete rifles under the Conviction, Elevation, and Tundra names, along with AR-platform and bolt-action barrels. Proof Research is a reference-standard brand in the premium precision-rifle barrel market.
