A simple replacement part to allow full auto firing out of a Nerf Rival Charger. It uses the magazine spring's compression to feed rounds into the flywheels at an extremely high rate of fire.

NOTE: This mod puts a large amount of friction on the motors, and the stock batteries are not powerful enough to fire all the rounds without stopping and getting jammed. In order to use this mod, I would recommend a full rewire and an upgrade to an 11.1v airsoft LiPo battery. If you've modded a Nerf blaster before, this should be a simple task for you. If you haven't, then it could be tricky. In order to replace the stock rev switch, you will need to Dremel out a section of the grip to make room for the new switch. This could be tricky if you've never used a Dremel before.
