Perun HPA Trigger Board replaces mechanical contacts in your HPA system and provides lots of useful features. Optical and magnetic sensors eliminate moving parts that are prone to damage, thus increasing the reliability. The elasticity of this unit gives you certainty, that 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.
