Barrels

Quality Match Grade Drop-In Barrels from EFK

All of EFK's products are manufactured from the highest quality 416 Stainless Steel for a lifetime of service and durability. They use the finest material available (type 416 stainless steel). Machining processes are accomplished on CNC equipment for the highest close tolerance production. Heat treating is done in a vacuum furnace for clean, consistent hardness of 40-43 Rc. Barrels are bored and rifled using EDM process (electrostatic discharge machine). This process produces greater accuracy (+/-50 millionths of an inch) and a superior finish (16 RMS or better). It also creates less stress than button or broach cutting resulting in a more durable and accurate barrel.
