The Electronic MOSFET Unit is the perfect way to upgrade your AEG airsoft gun. The Electronic MOSFET Unit will act as a replacement for your current trigger switch assembly. It will provide a crisp clear trigger break every time you pull the trigger and will eliminate the electrical resistance found in a normal switch assembly. This results in more voltage to the motor for a higher rate of fire, while producing a slower over all battery drain. Furthermore the Electronic MOSFET Unit will last a lot longer than any standard switch assembly to help keep you on the field.
