2922(r) Parts
A rifle assembled in the United States from imported parts may have no more than 10 of the listed imported parts. On an AK the parts that count are the receiver, barrel, trunnions, muzzle device, bolt, bolt carrier, gas piston, trigger, hammer, disconnector, pistol grip, stock, handguards, and the magazine body, follower and floorplate. Builders swap enough of them for US made parts.
3Receivers
An AK receiver is either a folded sheet of steel, the stamped receiver, or a solid block machined into shape, the milled receiver. The first AK-47s were stamped, the Soviets switched to milled for strength, then went back to stamped with the AKM. Milled receivers are stiff, heavy and costly. Stamped receivers are lighter, far more common and easier to build on, but rivets can loosen with hard use.
