Proof Research 264 Bolt Action Steel Barrel

Proof Research 264 Bolt Action Steel Barrel is made in house with the exact same commitment to quality and repeatability as they employ on their carbon fiber barrels. The drilling, rifling, and lapping process is identical to their composite barrels.  Proof Research start with the same steel as they use in the carbon fiber barrels.  It is a double stress relieved 416R stainless steel, a pre hardened chromium stainless steel that was specifically designed by engineers in collaboration with rifle barrel makers to provide the consistent, high quality and durability the firearms industry demands.

By designing a bolt action barrel blank, Proof has opened up countless options for chambering in your favorite caliber and having the ability to fit a large variety of actions. Their bolt action barrels are available in a variety of calibers, lengths, contours and twist rates. Your bolt action barrel will arrive ready for thread and chamber by your gunsmith.
