Not really. Russians sanctioned/approved production in most of the Warsaw Pact countries. Those countries created their own parts supply, and own modification (e.g. Czech VZ58, forearm on yugo, etc). Poland preferred machinning vs stamping. I am talking about true "soviet" AKM that was made in Izhevsk, with soviet serial numbers, quality control and such. "Copeis" (yugo, romanian, polish, etc) can be compared because they are available here. There is no comparison to original one, that is available for most, with the exception of people that have "bring backs" or collectibles.then you basically can't call anything an AK-47/AKM because the only true AK-47/AKM are the original russian machine guns.
Everything else is just, literally, a copy or a variant.
If your just talking Russian variants, there are hundreds of thousands of Saigas and SGLs in country today, made on the same assembly line as the current AK100 series rifles.
Saiga is made at the same factory, but not same line, different quality control. Warsaw block had "dual" quality control - civilian and military (for all military products). Russians still have that. Saiga is considered "civilian" product, and is inspected to different standards.
