AK builder, one of our sponsers here, has kits I think. The receiver blank(shell) is a fine way to go if you dont mind doing alot of cutting with a moto-tool. I've done several this way. It can be done with a moto tool, hand drill (a drill press is much better), all thread barrel press, and calipers. I beleive calipers are essential for getting the hole locations correct. A spot welder or mig/tig will be needed for the lower rail installation. And a mapp torch is great for hardning the rails and hammer/trigger pin holes.
