Nice work BM! Using basic tools requires a lot of patience. I think you could worry your way out of prison if you had an unlimited supply of plastic spoons.

I bought an electropneumatic pball gun a few years ago with the intention of a very noisy airsoft project. The gun has changable fire modes: semi, 3rnd burst, 6rnd burst, f/a. Stripped down, the important stuff is pretty small: about 2.5" tall, 8" long, 1.25" wide. The gas pressure applied to the pneumatics operating system and the breech are separately regulated so it's possible to modulate muzzle velocity without affecting the recoil cycle (i.e. it can be downtuned to safe muzzle fps without sacrificing recoil perf'). ROF is electronically controlled and is quite easy to adjust (turn a pot').

At FA, this thing is a loud monster.

I think you could hide a decent sized CO2 bottle in a belt bag or even within your rec'r itself. The strong pneumatics could also cycle a bolt plate for more metal clinking fun.

Pretty cheap too at $300 (used) including regulator on a Canadian pball forum. If I had the time, I'd put it into a MG, but I'm not sure if I'd ever get around to it.
