If nothing else, this "kit" does not provide a way to "put a shoulder stock on a pistol-length firearm", which is what the ATF is really concerned about. With this kit and a Ruger pistol you can either have a normal pistol or a carbine of legal proportions. There's no way to assemble an illegal configuration short of modifying parts, which I'd say is outside the discussion at hand.
This is just my take on it, and if a real-life lawyer (which I ain't) would like to straighten me out, I'll surely pay attention.
