For airsoft players who demand the very best from their replica, trigger response and reliability are non?negotiable. The PERUN V2 Lightning MOSFET ETU delivers exactly that, and more. As the most advanced electronic trigger unit designed for Version 2 gearboxes, it raises the bar for out?of?the?box performance. From its industry?leading trigger sensitivity to its fully programmable fire modes, every feature is engineered to give you a tangible advantage on the field.

Right out of the box, the PERUN V2 Lightning offers the highest trigger sensitivity of any Perun product to date. You do not need to modify your trigger or gearbox, because the sensitivity can be fine?tuned at any time, even in the middle of a game, to match your personal preference and playstyle. Whether you prefer a feather?light hair trigger or a more deliberate pull, the adjustment is instantaneous and intuitive.

Two of the most critical features for high?performance AEGs are active braking and pre?cocking, and the PERUN V2 Lightning handles both with exceptional finesse. The active brake stops the motor after every single shot, preventing the spring from remaining compressed and eliminating overspin, which is the dreaded double shot that can plague high?rate?of?fire builds. The braking strength is fully adjustable, and if you prefer, you can turn it off entirely. Pre?cocking takes trigger response to another level. When enabled, the piston stays locked to the rear after each shot, with the spring already primed and compressed. The very instant you pull the trigger, the follow?up shot fires, giving you a split?second advantage that can decide a close engagement. The pre?cocking strength adapts automatically to your current battery voltage, ensuring the piston always lands in the optimal position regardless of whether your battery is fully charged or nearly depleted. Crucially, active brake and pre?cocking settings are independent of each other, so you can dial in exactly the combination that works for your build. Releasing the spring safely after using pre?cocking is straightforward: switch to semi?automatic, fire one shot, and hold the trigger. After three seconds, a second shot with maximum active brake will fire, decompressing the spring and returning it to a neutral, safe state.

Inspired by the legendary Steyr AUG, the PERUN V2 Lightning features a true two?stage trigger function. A light, half pull fires one firing mode, while a deep, full pull seamlessly switches to another. You can assign unique combinations to suit your playstyle, with available pairings such as semi and burst, semi and auto, or burst and auto. This gives you instant access to two different engagement options without ever taking your finger off the trigger.

The PERUN V2 Lightning comes with a proprietary selector plate that fits most AR?style and M4?style AEG replicas straight out of the box. For replicas with non?standard selector plates, the package includes a special magnet with double?sided tape and a positioning tool, making installation straightforward and free of permanent modifications. Once installed, calibrating the selector is easy. The unit uses magnetic Hall?effect sensors, which are completely immune to ambient light. This means your selector position is detected perfectly every time, even in replicas with cut?out or skeletonised receivers where external light could otherwise confuse inferior optical sensors.

The PERUN V2 Lightning works without modification in most TM?spec V2 gearboxes. It is compatible with brushed and brushless motors, all gear sets including DSG builds, and batteries ranging from 7V to 17V. Rear?wired power configurations are fully supported. For a complete compatibility list and any rare exceptions, please refer to the manual included in the package. Beyond its performance features, the unit includes an integrated electronic smart fuse for enhanced circuit protection, plus full programmability for fire modes such as binary, DMR mode, rate?of?fire reduction, and burst settings. Brushless motor support is built right in.

The PERUN V2 Lightning MOSFET ETU is not just another upgrade; it is a complete transformation for your V2 AEG. From its out?of?the?box trigger sensitivity to its independent active brake and pre?cocking, from the innovative two?stage trigger to the rock?solid Hall?effect selector detection, every detail has been refined for performance, reliability, and ease of use. Whether you are a competitive speedsofter or a dedicated DMR builder, the PERUN V2 Lightning gives you the edge you have been looking for.
