I've got a yugo 59/66 sks that has been "tacti-cool'd" with a tapco stock, missing the fixed magazine, and a railed receiver cover. I want to find an original replacement stock, magazine, and cover to fit it, but I dont know if other sks stocks and magazines will fit and work or if I have to have yugo parts. There is a larger selection of other parts but most are pretty expensive and I dont wanna waste money on stuff that doesnt work. Anyone have any knowledge in this area?
