At peak production, Kalashnikov Concern (formerly Izhmash) can produce around 95 units per hour (about 832,000 units per year). Because of its stamped-steel design it is not possible to manufacture the AK-47 series efficiently in small plants, due to the large amount of metal stamping equipment needed for mass production. However, the milled-steel AK-47 has spawned a cottage industry of sorts and has been copied and manufactured (one gun at a time) in small shops around the world.
