EFCS Unit M4 Mid-Rear Wire [Ares]

EFCS (Electronic Firing Control System) is a precisely and professionally made mid-rear wiring MOSFET system designed for ARES and Amoeba M4 series airsoft replicas.

The device enables the programming of different firing modes and protects the motor from short circuits. EFCS has helpful traits such as adjustment of the trigger work response time, gearbox protection system, and gear sensor. Moreover, the item replaces the mechanical trigger switches with an electronic circuit for enhanced durability and more efficient work. Another excellent improvement of this model is the Enhanced ABS & Precise Magnetic Sensor and Piston Position.

In addition, users get the following:
- increased responsiveness when shooting in semi-mode
- enhanced the rate of fire
- increased current resistance up to 30A
- extended battery lifetime

Because of the gearbox design, the piston stops at a random point in automatic-fire mode. For proper operation, it is necessary to have a functional gearbox cut-off lever, selector plate, reverse latch, trigger, and trigger block.
