It has always been a matter of time before someone decided to strike the back of a gas 'nade with a real firing pin, or that pumping out empties that's worth at least $30 each on is a good idea.
Runs off CO2. Holds up to 5 BBs. Single BB shot using the shell and no barrel results in 800+ fps.
Unless MB also makes some sort of barrel insert for real shotguns, the shell itself provides all the barrel the BBs will get. Single bore, linear loading means the BBs probably won't ever touch any choke on the way out.
