I have a saiga ak47 and want to have a few spare parts around [bolt, bolt carrier, etc.] but am wondering about compatibility. I am thinking of just getting a parts kit but don't want to waste the money if nothing will fit. options at the moment are Romanian, Yugo and Hungarian. Are you aware of any compatibility issues for the Saiga's? I know you cannot guarantee anything as there are many variables but if you know for sure some countries are too different to work I would appreciate the information.
