Our take: JG's MOSFET wiring harness for front-wired mini-plug AEGs fits any M4 / M16 / AR-style AEG that has battery wires running to the front of the gun (typically the hand guard area).
The MOSFET is an inexpensive yet performance-boosting upgrade that allows your AEG deliver more crisp shots, more energy, and develop faster trigger response. The wiring harness includes all pertinent wiring, connectors, and even the MOSFET chip itself, so it's mostly plug and play.
