| I think I am going to buy a G&G UMP this weekend and was wondering what upgrades I should do to increase the ROF. This does not include getting a new battery or motor. | |

| Change to a different spring. The more powerful means suffering of the rate of fire. I do not have concrete evidence, but experiance. My TM MP5 had a LOT slower ROF when i put in the M120 | |

| High speed gears, M90 spring, perfect shim job, bearing bushings, rewire, MOSFET, Deans plugs, swiss cheesed piston, polish the gearbox, etc... | |

| FYI, if you re-wire, make sure its 16g wire. | |

| Hey Booligan can you link me to that stuff I am having a hard time finding it and I know you can't link me to a MOFSET but I thought those only increased trigger response. | |

| What are you having problems finding? Any shop will have high speed gears, low FPS springs, shims, and bearing bushings. THe rewire you can either buy an overpriced kit or do it yourself for about $3. A swiss cheesed piston is when you drill a bunch of holes in the piston to make it lighter, therefore reducing the reciprocating mass and upping ROF. Polishing the gearbox is just that. Get a metal polishing kit and polish the gear area and piston rails, so they'll have less friction. Deans plugs you can get HERE for cheap. A MOSFET will decrease trigger delay and increase ROF, as well as make your trigger contacts last longer. EDIT: - RoboFURY wrote:
