I made this over the summer, and used it at fulda gap in november, but I decided to move on to a more limited ammo type of play. The gun works just like any ion should, and requires a remote coil to operate. The only issue is the power buttom on the board got knocked off during disassembly, and I never found it. A new one can be ordered from zdspb.com for $2.
I'm looking to get $75 paypal'ed and shipped obo, but will entertain any trade offers involving markers. (not interested in hoppers, tanks, etc.)
