PERUN V2.2 for G28 / HK417 completely replaces the original contacts and introduces modern electronic control for the VFC G28 / HK417 platform. The unit uses Hall effect magnetic sensors for trigger detection and optical sensors for detecting the selector position and sector gear, significantly improving reliability and eliminating contact wear. The integrated adjustable Clicker trigger system allows you to fine-tune trigger resistance, pre-travel and over-travel exactly to your preference. Programming is done via the fire selector and trigger, so you can change settings anytime during gameplay without disassembling the rifle. The unit works with batteries from 7 V to 17 V and handles high-performance builds with strong springs or high rate of fire. You can set a short, sporty trigger pull for fast shooting or a longer, more realistic trigger feel for precise DMR setups.
