ARES Ameoba / Ares M4 Series E.F.C.S. Metal Complete Gearbox Set for One-Piece Cylinder - Rear Wire

The ARES Ameoba / Ares M4 Series E.F.C.S. Metal Complete Gearbox Set is an upgraded version of the previous complete gearbox set that features a reinforced full teeth piston, gearbox shell, and an upgraded EFCS which is ARES's MOSFET system.

The more recent AEGs from the ARES Amoeba series use their updated gearbox with the electronic control unit inside. This particular control unit allows the user to alter the method by which their M4 AEG shoots. The standard M4 has a safe, semi-auto, and full auto fire selector but what the control unit allows you to do is allow you to shoot in either, Semi / Burst, Burst / Full Auto, or Semi / Semi as well.

Since this is a version 2 gearbox, it will fit in MOST brand M4 AEG as all gearboxes are relatively the same shape and size. This is because some G&P and VFC bodies change depending on the model so there may be a need for some modifications. For you to alter the fire selecting mode, you will also need to purchase the ARES Electronic Firing Control System.
