This was created by Derek Miller who has patents pending on this. This is a Belt-fed 12 Gauge which is made from the Upper Receiver of a Ar-15 or an M-16, if made from an AR, it becomes a Semi auto shotgun but with the M16 it is now a Fully automatic 12 gauge shotgun. Believe it or not, this is a prototype, you might be able to tell from it being on Derek’s deck and it is wobbling back and forth at a not so comfortable rate. The bugs are being worked out so the shells can fly out at a good rate and prevent jamming. Soon you too can make our buy your own and keep those kids off of your damn lawn for good.
