My dad gave me a pre SKS today. I know he got it before the ban so its at least that old. He has had it for a while and it has never been shot. He has no use for it and is not really into guns so he just gave it to me. I think its a chinese because if I remember correctly it had a shorter stock but it might be russian. Any tips? I would like to put a bigger stock on it. Do they make black polymer parts for it? I want to keep it pretty simple, I can tac out my AR. I would entertain the notion of a pistol grip with a retractable stock if that is possible.
