I am in the process of buying a AK47 in 7.62x39, but I don't really know too much about them. I want to spend $350-550. Can you guys tell me what to look for and what to stay away from. I have looked at a few CIA rifles on the web and in person and they seem to be in my price range, are they any good? I don't want a show piece and could care less if it gets dinged or scratched, I just would like a good SHTF rifle that will eat any ammo. Thanks in advance!
