Thanks for the compliment bro, I really like it a lot. Since its a non folder it really lightens the rifle up nicely. And, I have always liked the look of the Krinkov style stocks.
Anyway, on to the information that you requested. There are two different styles of stocks on there. One for Chinese models, and one for European models. Stamped only I think?
Do a search for RPB industries. OR, gunmallusa.com They have an AK section. Here's the link, but I don't know if it will work.
If the link doesn't work the part # is
AKKRST-E1. $35 + shipping.
The only thing is you'll have to drill your own screw holes when you get it.
