Perun MOSFET is the smallest MOSFET device on the market. Specialized, ultra-low resistance transistor used in Perun channels power from the battery directly to motor, while the mechanical contacts only have to handle small currents to turn MOSFET on and off. That greatly extends their service life and lowers overall resistance resulting in a more dependable replica with higher rate of fire. The Perun Mosfet Unit is an ultra compact MOSFET built to be as compact as possible, requiring the smallest amount space possible. This MOSFET is designed to achieve a higher rate of fire and trigger response, as well as protects the mechanical trigger contacts by directly bypassing the contacts and going straight to the motor. The unit itself is so compact that it can be fit in any Airsoft AEG, allowing you to wire the unit in down buffer tubes and in tight handguards. Signal wires will need to be purchased separately. Operating voltage - 7V to 17V Maximum muzzle velocity - 650 FPS with 0.2 g BB's Maximum rate of fire - 50 rounds per second Dimensions - 14x6x3 mm Instruction manual with installation tips can be found here !
