Perun MOSFETDescription Perun MOSFET one of the smallest MOSFET device on the market. Thanks to 14x6x3mm dimensions it can be used even in most confined spaces. But dont be deceived by its size it can take a lot. Its operating voltage is from 7V to 17V and it can operate with a maximum muzzle velocity of 650 FPS on 0. 2 g BB's. Do you think about a higher rate of fire? Perun MOSFET can take up to 50 rounds per second. Specially designed ultra low resistance
