For those with means and motivation (money and machine tools), cheap automatic weapons can be somewhat-easily produced from plans and diagrams online, with parts that can be bought from regular industrial suppliers, or sometimes big-box hardware stores.
Not naming the specific plans I've seen, of course. If someone wants to know, they can look for themselves.
Quality is to be suspect, but if you only need to throw out ~20 rounds of 9mm at something that isn't very far away, it'll get the job done.
