IMO, the downside to using a Draco is that the barrel is still 12" long. Add on a flash hider or brake, and that's really not much shorter at all than a standard AK. I wanted something more like a Krink, in the 8" to 10" range. So I took a standard parts kit and sent it to Pat McHenry (

I don't really like the Romanian/Polish/German folding stocks - they're just not very comfortable to me. Same with the Hungarian ones. The Russian triangular side-folders are much better, but a bit expensive and more complex to install, what with the front latch. The best stock I could find was the Chinese Type 56-1. It has a solid lockup, installs with two basic rivets, and has a couple side plates for a nice cheek weld. Those stocks with AK trunnions are rare and expensive, but I found a cheap ($50) airgun (

The result? A shorty AK that's actually pretty short and still has a good folding stock. The only thing left is to find a Larue Irondot for it to make up for the really short sight radius.
My cost for the whole thing was $125 for the kit, $150 to have it cut down, $85 for the Nodak receiver, $30 for a Tapco semi FCG, $200 tax stamp, and $50 for the donor airgun. Total cost $440 plus tax stamp.
