Perun HPA Trigger Board V3 Gearbox

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. The elasticity of this unit gives you certainty that HPA replica made from parts made by different manufacturers will not have any incompatibility issues. 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.

HPA Trigger Board works with Perun accessories for V3 gearbox, like Clicker V3.

Based on optical and magnetic sensors – Magnetic trigger sensors ensure that you will no longer have any problems with breaking mechanical switches from stock HPA trigger boards. Optical selector sensors 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 the selector is set to “SAFE”.

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, it immediately lets you know what it might be, making troubleshooting much easier.
