Pro-Arms 3 Burst FET System for Marui AEG. Installs into any AEG to give you a 3-shot burst function. Note that not all AEG's have enough room to store this FET so ask our sales representative for more information. For experienced airsoft players with knowledge of how to upgrade guns. Expert installation recommended!
Installation steps are as follows:
Open the gearbox and remove old wiring. Lead the white signal cords (S+) and (S-) to the switch tabs in place of the old wires. Polarity does not matter. Lead the red and white motor cords (M+) and (M-) to the motors. The red (M+) goes to the plus side. Reassemble the AEG and connect the battery. The burst device will beep four times. Semi-Automatic is now a burst mode instead. Removing the jumper tab by pulling from the plastic part retains regular semi-auto functioning. When you reconnect the battery, the burst device will beep twice to indicate a normal semi-auto function. If the battery voltage is incorrect, the burst device starts continuous beeping after two seconds. When the battery power becomes too low, the burst device makes a continuous long sound signal.
