I am getting a second primary weapon (one for me one for my wife) and want to use common ammo.
You just came off as being unknowledgeable because you responded to the question "Whats the best AK-47?" with an answer that included describing that one as being one of "machine gun quality." In reality the civilian Kalashnikov rilfes like the Krebs, VEPR K, and Arsenal rifles are reputed to have a much high degree of quality than their select fire brethren. Fit, finish, and not to mention the triggers are so much better on these rifles.
