okay i dont no if any1 here will no wat im talking about but ill put it up any way, i was thinking about making a bb hybrid, it would combine an air powered bb gun with a coil gun (check here if you dont no wat a coil gun is
http://home.comcast.net/~irwinner/coil_gun.html) the bb would start off being pushed foward by the air pressure, once it got to a ceertain point down the barrel it would triggger the first coil would fire (i would use an ir led as a sensor) then it would trip another censor firing the next coil and so on, i dont no how well this would work thats y its only a THEORY, just thought i would post it.
