On a typical stamped receiver rifle you need to replace 5 parts with no muzzle attachment and 6 parts with a muzzle attachment.
On a typical milled receiver rifle you need to replace 4 parts with no muzzle attachment and 5 parts with a muzzle attachment, because there isn't a barrel trunnion, it is part of the receiver.
When building an AK pistol, these regulations do not apply. You can not have a stock or forward pistol grip on a pistol.
