It began as a standard Drone body (painted) and all I did is needed add an alternate barrel to the bottom. First dremal or saw off the two round hubs in front of the trigger housing to allow for a flat surface on which to mount the new barrel. To construct the new barrel I used the IR LED form an old Drone and the body of an old telescope. Next open up the tagger and drill a hole in the side for the wires connecting the two barrels. Then cut and strip the red and black wires going to the IR LED, make sure to leave enough slack on each side to work with. Connect the black wire to the black wire from the new barrel. Connect the end of the red wire connected to the circuit board to two switches, and connect one of those switches to the old barrel and one to the knew one. PUt the tagger back together and attach the new barrel to the bottom, I used a hose clamp and it seemed to work fine. This mod makes the tagger heavier and a little unwieldy, however the range increase is worth it. It has doubled the effective range and with the right switches flipped both barrels fire at once acting kind of like the shot blast for the LTX. The only drawback is that the tagging range far exceeds the lock-on and hit confirmation, so you can land tags not know it.
