This file is a bolt-on machine gun upgrade that will fit any AR platform weapon. It works by spinning a TPU or Nylon paddle attached to a dynamite 12t 12v hobby motor via spur gear, and powered by an NIMH battery, actuating the firearms trigger automatically. The system is meant to be controlled via a switch on the right side of the gun that can be actuated with the finger in a safe-fire position (pointing straight forward on the side of the gun).
