I like it, but you could probably build it yourself using part purchased online. It has an AMD-65 stock, and I think a Galil fore grip. He used a fold by hand AK-47 reciever(no holes drilled,or maybe a pre bent one, but it looks like he made a custom fore end ferrule, or cut the notch for an existing one,and another custom piece to match the 10/22 receiver with the AMD-65 reciever.

Mine already has the weaver mount.
So if you already have a 10/22 and some time and tools you can make a piece to match up the receivers. I think you can build this thing pretty cheap. As a matter of fact, I have a failed fold by hand project that looks like a candidate for this thing. It was just very slightly off of square.
