JeffTron AR Mosfet (V2 Gearbox)

AR mosfet by JeffTron

The AR mosfet by JeffTron is designed for airsoft replicas with a V2 gearbox (mainly AR15 - M4/16 weapons) with a battery located in the stock. Thanks to the compact micro mosfet III integrated into the DeanT connector, it saves space and ensures easy installation. The wiring is prepared to connect to the original trigger contacts in the gun, allowing for quick and easy installation. The mosfet improves rate of fire and extends battery life.

The mosfet prevents trigger contact burning and is fully compatible with common batteries up to 17V, including Li-Pol batteries 7.4 – 14.8V and Ni-xx 8.4 – 12V. In idle mode, it draws no current, ensuring energy efficiency. The electronics are protected with a coating that provides water and moisture resistance.
