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 like the Clicker V3. It only replaces the trigger board and does not replace the FCU itself. Manual here 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 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, immediately lets you know what it might be, making troubleshooting much easier. The HPA Trigger Board V3 works without problems with any battery from 7.4V to 11.1V.
