Description
Ares L85A3 – AR-085E – EFCS Unit with Wiring
This is an Ares EFCS (Electronic Firearms Control System) unit supplied with its wiring, listed for the Ares L85A3 under code AR-085E. The EFCS is the electronic trigger and control board inside Ares electric rifles, so this is the part to replace if the original unit or its wiring has failed or been damaged.
The Ares L85A3 is one of the most popular replicas of the British Army’s current-issue rifle, and its EFCS gearbox is a key part of its performance. Supplying the unit complete with wiring makes a repair more straightforward than replacing parts piece by piece.
What the EFCS does
The EFCS reads the trigger electronically and controls the motor through its own circuitry, rather than relying on traditional mechanical trigger contacts carrying the full motor current. Ares describes its EFCS as being there to give consistent performance with every trigger pull.
If your rifle has stopped firing, fires erratically or will not respond on one fire mode, a fault in the control unit or its wiring is one possible cause, but check the battery and connector first.
Fitting
The EFCS sits within the gearbox area, so fitting it means stripping the rifle and, usually, opening the gearbox. On a bullpup like the L85 that involves more dismantling than on an M4. This job is best suited to players experienced with AEG internals, or to an airsoft technician.
