Perun for AUG Magnetic sensors coupled with magnet included, installed directly on the trigger, allows you to remove the bar that connects trigger with the gearbox, making the trigger pull much smoother. Optical detection of the sector gear position ensures reliable single fire function. (Cycle Detection) Only replicas in Tokyo Marui standard are compatible with this mosfet, among which are those manufactured by: Tokyo Marui, Classic Army, JG, ASG. Adjustable Trigger Sensitivity - The trigger can be set to 5 sensitivity levels for both first and second trigger stage, ranging from short pull needed to fire a shot, to a long one. No modification to the trigger or the gearbox is needed and the trigger sensitivity change is possible even in the field. Selectable firing modes – User can choose firing modes available after short or long pull of the trigger: SEMI ONLY, BINARY, SEMI-AUTO, SEMI-BURST, BURST-AUTO. Active brake - active brake stops the motor after each shot preventing spring compression or in case of replicas with high rate of fire, overspin (double shot problem). Binary trigger - Allows for easy double shots in semi-automatic setting. After enabling this mode, if semi-automatic fire is set, shots will be fired not only when the trigger is pulled, but also when it is released. Rate of fire reduction - Reduce the rate of fire in automatic or burst fire to save ammo or make the replica shoot in a more realistic fashion. DSG – a sector gear detection mode specially prepared to work with dual sector gears. Low battery voltage alarm - Dedicated for Li-Po and Li-Ion batteries. Should the battery voltage fall to a dangerously low level, user will be notified by short sound signals that are repeated every minute. This may also be freely switched on and off. Diagnostic system - Constantly monitors the replica and the mosfet itself. In case of any problems, immediately lets you know what it might be, making troubleshooting much easier. Electronic fuse - Will save your r
