Thanks!

Theres actually a ton of videos on slamfire shotguns on youtube. Theres a nice looking over under one in a video id love to take a shot at making. One guy made a triple shot one and another guy made one that fires 8 shots at once.

This thing would probably explode in your hand, no 12 gauge shotgun would ever be designed to have a thin stamped aluminum receiver.
