Does anyone have ideas for a totally over the top vortex gun? Im already building it out of steel and im going to put on a paintball Co2 tank adapter. Im also going to try an electric solenoid to put air into the vortex. I woud like to have removeable cartrages that can be kept on my belt and put on to the gun rapidly, mabee they will hold 2000 bb's?
Any ideas are welcome and appreciated!!!
