JeffTron AK MOSFET (Gearbox V3)

AK MOSFET by JeffTron

AK MOSFET by JeffTron is designed for AEG airsoft guns with V3 gearboxes (especially AK series) with battery placed above the gearbox under the dust cover. Thanks to the compact Micro MOSFET III integrated directly into the T-Dean connector, it offers maximum space savings and easy installation. The wiring is prepared for connection to the original trigger contacts, making installation quick and easy, but it does require soldering. The MOSFET is an electronic switch without active braking, replacing the traditional mechanical switching through trigger contacts. This eliminates contact arcing, prolonging their life while also improving circuit efficiency. The unit allows for a higher rate of fire and longer battery runtime compared to standard wiring. Especially suitable for experienced technicians and airsoft service professionals, as installation requires advanced knowledge of AEG platforms.

Warning

Installation must be performed by a qualified technician capable of soldering and disassembling an AEG. Do not use a transformer soldering iron. While the MOSFET is compatible with most standard V3 gearboxes, 100% compatibility cannot be guaranteed in every case.
