The Saiga is a true Russian AK but they had to move the trigger group back to put a crappy stock on it for import laws I won't go into. Yes, it's basically the same thing - a stamped receiver Kalashnikov made in the same factory in Izhevsk, Russia. Technically anything else is an unlicensed copy but Izhmash just licensed 5000 AK74s to be produced by Azerbaijan for themselves (presumably).
