Proof Research AR-15 Stainless Steel Barrel

PROOF Research is known for their Carbon Fiber barrels and for accuracy. Did you know that Carbon Fiber  are not the only barrels that Proof Research develops and offers? Proof Research joined with Lawrence Barrels in 2012 who had 15 years of experience in manufacturing precision steel barrels. These stainless steel barrels are made in-house with an absolute commitment to extreme accuracy and quality. Stainless steel barrels are double stress-relieved 416R stainless steel. 416R was specifically designed by engineers in collaboration with barrel makers and rifle manufacturers to provide the consistency, high quality and durability the firearms industry demands.
