Perun V3 Integrated Drop-in MOSFET

The Perun V3 Integrated is the Version 3 counterpart to the Perun V2 Lightning ETU, made for players running a Version 3 gearbox who want a sharper trigger and fewer parts to wear out. Rather than relying on metal contacts, this airsoft MOSFET reads the sector gear and selector plate optically and the trigger magnetically, so there is nothing to burn or pit over time.

What sets it apart is the built-in Clicker. You can adjust the trigger break, pretravel and overtravel, and make the break light or take it out altogether. A standard fit needs no soldering: it drops into Tokyo Marui-standard V3 gearboxes, and two sets of wire extensions cover common layouts such as AKs with the battery under the top cover or in the stock, G36 and MP5K.
