[PERUN] PERUN HPA Trigger Board V2 (Released late November to early December 2025)

This board features an evolved, high-precision magnetic trigger sensor that dramatically improves the trigger feel of aftermarket HPA units.

This allows for precise settings, such as allowing the gun to fire just by touching the trigger, or allowing the next bullet to be fired by pulling the trigger all the way and then releasing it very slightly.

■Highly secure system

The PERUN HPA Trigger Board is equipped with a magnetic selector detection system and will not fire when the SAFE position is detected.

If you cannot use the included magnet selector plate (for STD M4), you can use the included magnet by gluing it on.

■Overwhelming energy efficiency

Since the HPA system itself is energy-efficient, a Li-Po 7.4v 500mAh battery is sufficient.

■Highly compatible system

It can be installed as a standard feature on any model that can incorporate PERUN HYBRID V2 PRO, and Clicker V2 can also be used.
