Wiring set and switch set for rear wired M4/M16 AEGs. Includes MOSFET chip. A MOSFET chip replaces the standard mechanical trigger switch. The MOSFET reduces resistance in your AEG providing a faster trigger response and also eliminates arching which allows the use of higher voltage LiPO batteries. Basically, upgrading to a MOSFET will increase the rate of fire of your AEG and reduce the wear on your trigger mechanism.
