Perun HPA Trigger Board - V2

Perun was founded in 2016 with the goal of developing and producing MOSFETs and other parts for airsoft replicas.

Years of design and testing have allowed them to offer products that enhance the performance of your replica.

This Perun HPA Trigger Board replaces mechanical contacts in your HPA system and provides lots of useful features.

Magnetic sensors eliminate moving parts that are prone to damage, thus increasing reliability.

Adaptive trigger control allows switching from a very short trigger travel to a long one even in the field, with almost any trigger, including stock ones.

Works with a broad range of Perun accessories for V2 gearbox, like Clicker V2 and V2 PRO or Speeder V2. It only replaces trigger board and thus does not replace the FCU itself.

Fully based on magnetic sensors – All-magnetic sensors ensure that you will no longer have any problems with breaking mechanical switches from stock HPA trigger boards. External light is also a non-factor. Selector sensor can be calibrated, allowing fast installation and reliable selector operation, including detection of SAFE position and therefore ensuring reliable, electronic safe mode.

Electronic safety – Now, regardless of how sensitive the trigger might be, you can be sure there will be no accidental discharges when selector is set to “SAFE”.

Proprietary selector plate provided – A proprietary selector plate with attached magnet is provided for AR-type replicas. It has been proven to work with almost any standard V2 gearbox and AR replica on the market. For all other cases, and additional selector magnet is provided, to be glued to the stock selector plate.

Adjustable trigger sensitivity – The trigger can be set to 8 sensitivity levels for both first and second trigger stage, ranging from a very 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.

Diagnostic system – Constantly monitors the board. In case of any problems, immediately lets you know what it might be, making troubleshooting much easier.

Selectable Firing Modes - SEMI ONLY, BINARY, SEMI-AUTO, SEMI-BURST, BURST-AUTO. 

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.

DMR Mode - Required on some fields for DMR replicas. It allows only single shots and within certain time intervals. When enabled, follow-up shots cannot be fired sooner than after 0.25 s, 0.5 s, 1 s, 2 s or 3 s, depending on chosen setting. It can also be used voluntarily for more realism – to force the shooter to not fire too fast, reflecting the effects of recoil in a real 7.62 mm rifle.

Programming of all the settings is done solely by using selector and the trigger. That allows changing the settings in any moment. All settings are set independently for each selector position, so you can program the mosfet exactly the way you want, for example semi on semi and binary trigger on auto.

The HPA Trigger Board V2 works without problems with any battery from 7.4V to 11.1V.
