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.
