The Gate PicoSSR 3 Mosfet is the smallest non-Active braking commercially-made airsoft unit on the market. If you have always wanted to run a Mosfet but couldn't find the room in your AEG, the PicoSSR 3 is the best solution. At an extremely small size of only 4x6x18mm, the PicoSSR 3 can fit inside any AEG. Not only is the PicoSSR 3 small but it uses tough components allowing it to handle up to 15 volts. It is also resistant to immersion in water and this Mosfet is compatible with most AEGs.
