I had a c39. Although I liked it you cannot customize it very much. Is has a different rear end than other ak variants. It has two tangs so you have to modify it and I only found one stock that I could make fit. And it wasn't a side folder. Never had any problems with it other than having some fte's. I think that was the mags I was using. And it doesn't have the cleaning rod like most ak's do. I like the cleaning rod. I would get either another ak or get an ar. Personally I would get an ar. Or you could get a wasr and customize the heck out of it. Good luck.
