Your EFK barrel is the finest pistol barrel made in the world because of the care exercised in manfacturing and the unwillingness to compromise on any step of the process.

• Only the finest material available are used (type 416 stainless steel)
• Machining processes are accomplished on CNC equipment for close tolerance production.
• Heat treating is done in a vacuum furnace for clean, consistent hardness of 43-45 Rc.
• Barrels are bored and rifled using ECM process (electrical chemical machining). 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, broach cutting, resulting in a more accurate barrel with greater durability.
