Bad-ass All Metal Rubber Band Gun and Rubber Band Machine Gun!
“Mezamashi TV” did this short feature on a guy who makes fancy rubber band guns out of metal. It is all in Japanese but you get the idea of these bad ass rubber band guns just by watching the video. Some background:
His day job involves metal working, so he has the knowledge needed to make some pretty bad-ass rubber band guns. His most advanced weapon is a rubber band machine gun, which fires off 30 rounds in about 2 seconds (it takes much longer to load).
He says that his hobby sometimes causes trouble at home, since his wife doesn’t like finding rubber bands strewn about the house in random places.
