Is every kalishnakov on back order?

Even SKS's are getting hard to find. I located a Norinco SKS at a local pawn shop. He hadn't priced it yet. I have seen a few Bulgarian versions with the grenade launcher attachment for sale at some of the local pawn shops. But finding a good Russian SKS right now is almost impossible.

Same goes for the Saiga 7.62 x 39s. Just can't find them right now. I have better luck finding the American assembled AKs. CTD still has some of those.
