I have two AK parts kits, contains everything you need to build an AK except for the receivers. You will have to source those yourself. They are the paratrooper style with a handle on the front grip. I forget the country of origin. They come with Tapco G2 trigger groups and one mag each.
They look like this:

note: that's just a pic from google, remember these are kits, not fully assembled guns.
$175 each or $300 for both.
I also have a pile of 30 round steel mags, random origins. $5 each, you clean out the cosmoline.
