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 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.
