That's kind of my thinking, but I don't want to build anything illegal. This would be so easy to build. And then you basically have a double barreled pump shot gun.
But when I read stuff like some guy having to defend himself in court because he had a string attached to a trigger allowing for rapid fire ... well. Better to be safe than sorry. It's not worth it for the fun of it.
