JeffTron AR MOSFET (V2 Gearbox)

AR MOSFET by JeffTron
AR MOSFET by JeffTron is designed for airsoft AEG replicas with V2 gearboxes (especially M4 / AR15) and rear battery configuration. Thanks to the compact Micro MOSFET III integrated directly into the T-Dean connector, it ensures space-saving and easy installation. The wiring is prepared for direct connection to the original trigger contacts in the replica, requiring only basic soldering. This MOSFET is an electronic switch without active braking, replacing traditional mechanical switching via trigger contacts. This prevents contact burning, increases their lifespan, and also improves efficiency of the replica’s electrical circuit. It allows for higher rate of fire and longer battery runtime compared to standard wiring. It is particularly suitable for experienced technicians and service centers, as installation requires advanced knowledge of AEG replicas.
