The gun's creator writes: "It uses a bullet-type design i made 4 years ago and i put them all on a chain; so it can shoot as many times as you want, it just takes a while to make more bullets. The one i made shoots about 30 Ft at 10 shots per second and has 40 "bullets" on its chain." Here is a link to some instructions on instructables and a link to a video of the machine gun in action."
