The Perun V3 Hybrid MOSFET is a complete trigger-replacement unit. 
This custom control system replaces all of the stock wiring and mechanical switch assembly to directly sense the gears, selector and trigger. 

This gives you extreme control over your gearbox with an array of smart control options while also eliminating all of the issues and inconsistencies inherent with the standard mechanical setup. 


The PERUN Hybrid V3 unit allows the full control over the selector options, assigning the following at will:
- safe
- semi-auto
- 2 to 5 round burst
- full-auto

Other useful settings include:
-Active Braking adjustment

-Precocking adjustment

-Burst settings

-Battery voltage monitoring


The Hybrid Magnetic Trigger and Optical Sector & Selector sensor systems allows for extreme reliability without the need for expensive apps to calibrate and control the unit. 
This means the PERUN units are superb value for money, providing an almost identical shooting experience for a fraction of the price.
