I little while back I heard that a guy had bought 1700 receivers from the American company that took over for Daewoo, South Korea. And that he needed to manufacture most of the parts. (semi Parts , assesories and ANY magazine) are not restricted to make by the federal government. Auto-Ordnance is making the 100rd c-drum again as well. Although I don't see how this USAS-12 is allowed.
But even a drum for a USAS-12 was always legal to make even after the reclassification (not the 94 ban though). It was just that there wasn't all that many out there and there was no market for the
