AceMOS Drop-In MOSFET UnitDescription AceMOS is a professionally made drop in MOSFET system designed by Acetech for Airsoft Electric Guns with a V2 gearbox. This system increases the AEG's rate of fire and trigger response time. It also limits unnecessary battery usage, reduces the amount of generated heat, and protects the circuits from the back electromotive force. Pre set wires are prepared in the rear facing position and are equipped with the Deans T plug connector.
