Perun V3 Optical is a device that replaces mechanical contacts in version 3 gearboxes with an electronic circuit based on MOSFET transistors and adds a multitude of new functions to your replica.

Elimination of mechanical contacts solves the problem of their gradual wear. MOSFET transistors utilized in Perun V3 have a much lower resistance than contacts, which also increases rate of fire. Small elements in the trigger mechanism responsible for semi-automatic fire frequently malfunction, especially in replicas built on parts made by many different manufacturers. Perun V3 minimizes the number of moving parts in your replica, increasing reliability and ensuring proper functioning of all firing modes. Perun V3 itself has no moving parts at all thanks to use of optical sensors for gear, trigger and selector plate detection.
Features
Use of a microcontroller enhances capabilities of your airsoft gun by providing possibility to set any combination of the following firing modes under SEMI and AUTO selector positions independently:

• - safe
• - semi-automatic
• - 2 to 5 round burst
• - full-automatic

Programming of all of the settings, not only firing modes but also switching active brake, precocking and battery protection on and off is done solely by using easily memorable sequences of fire selector switching and trigger pulls. That allows changing the settings at any moment in a matter of seconds, even under enemy fire.

One of the most important features of Perun V3 Optical is precocking. Fast trigger response can be a matter of victory or defeat, especially in CQB situations. With precocking enabled, piston will remain in rear position after each shot with spring already compressed, ensuring that next shot will be fired immediately after you pull the trigger. Microcontroller uses data from optical sensor to calculate current sector gear position and speed. With this information, after releasing the trigger, smart algorithms are able to transfer only enough power to the motor to make the piston stop in the correct position, or in high ROF setups, to let the motor inertia push the piston back and stop it using active breaking right. This saves your battery and reduces motor wear. Precocking works in semi, burst and full-automatic modes.

Perun V3 Optical has an active brake allowing to stop the motor after each shot. In case of double shot problem in replicas with high rate of fire, active brake will be an effective solution if you do not want to use precocking. It can also prevent compression of the main spring for a longer time, if you will fire a shot with AB on before a storing your replica for a longer time. Active brake can be switched on or off at any time in few seconds.

Battery protection mode is dedicated to Li-Po batteries. Should the battery voltage fall to a dangerously low level, user will be notified by short sound signals that are repeated every 30 seconds. This may also be freely switched on and off.

Double shot mode 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 pressed, but also when it's released.

The integral part of Perun V3 Optical is a ready for installation low-resistance wiring based on Muldental silicone wires, which are praised by airsoft techs and widely considered best for airsoft electric guns. Perun V3 Optical is available both front and back wired.

Thanks to use of exceptionally efficient and powerful MOSFETs, the device can be used in replicas with any main spring. The maximum rate of fire is 50 RPS.

Compatibility Perun V3 was tested with positive outcome in gearboxes of the following manufacturers: G&P, G&G, Classic Army, KWA, Ultimate, A&K, PJ, JG, Specna Arms, Cyma. That refers to gearboxes in Tokyo Marui standard.

Perun V3 works well with DSG setups, because optical sensors are not subject to mechanical stress seen in high ROF setups. Tests have shown that in some DSG setups precocking may be less reliable and has to be disabled. However, ROF provided by DSG makes use of precocking rather unnecessary.

Be advised, that Perun V3 will not fit to gearboxes diverging from that standard, for example ARES EFCS.
