It’s a WASR 10/63 AK 47. It’s got a single stack mag well instead of the double stack. I was trying to make sure if I just filed it open enough to accept the high capacity magazines that nothing else would need to be done. I took it bye a local gunsmith & he seems to think that’s all it would take. He said it would probably be around $100 for him to do it so I may go that route instead. Needless to say I didn’t pass it up, the price was just too good!
