After I took out the dozen or so screws, I pulled the guy in half to take inventory and figure out what I needed. Turns out, not much, so I stripped the hell out of it but saved the parts "just in case". For some odd reason, I thought this was an automatic, but it turns out the trigger pushed a lever that pushed the darts into firing positon. The batteries ran two motors in the front that actually pulled the darts out. I plan on finding either A) A very slow spinning motor B) Motor and Gearbox C) Both, and having the barrel spin continuously as LEDs flash, simiulating charging and firing.
