JeffTron Micro MOSFET III with Wiring Hi Capa Quick Spring Change (QSC) systemThe JeffTron Micro MOSFET III with Wiring is an ultra compact and reliable MOSFET designed to protect trigger contacts and improve electrical efficiency in AEG airsoft replicas. Despite its small size, this MOSFET effectively redirects high current away from the trigger switch, reducing electrical arcing and wear while maintaining a crisp and consistent trigger response. Pre wired for convenience, the Micro MOSFET III is ideal for builds with very
