JeffTron Micro MOSFET III with Wiring

Micro MOSFET III by JeffTron

The Micro MOSFET is a professionally designed minimalist electronic switch without active braking. It replaces standard mechanical current switching through trigger contacts, thus eliminating contact burning and increasing the efficiency of the power circuit. This unit allows for a higher rate of fire and longer battery life compared to basic wiring. This is a compact module, best suited for experienced technicians or airsoft service centers, as installation requires advanced knowledge of AEG internals.
