Regular price $125.00

The Perun ETU for VFC G28 / HK417 is a complete trigger and electronics upgrade that replaces your stock trigger unit with a fully adjustable, high-performance system.

It combines optical sensors, magnetic trigger detection, and a built-in adjustable clicker trigger, giving you faster response, better reliability, and a realistic trigger feel—all in one drop-in unit.

Designed specifically for VFC G28 and HK417 replicas, this is the upgrade that turns your rifle into a true DMR or high-performance battle rifle.
