Perun was founded in 2016 with the goal of developing and producing MOSFETs and other parts for airsoft replicas.
Years of design and testing have allowed them to offer products that enhance the performance of your replica.
The Perun V2 Lightning offers the fastest out of the box trigger sensitivity of their range to date.
Replaces the mechanical contacts in your airsoft replica and introduces a wide range of useful features.
Optical and magnetic sensors eliminate moving parts entirely, providing exceptional reliability and flexibility—working with almost any combination of gearbox shells, triggers, selector plates, and sector gears.
Adaptive trigger control lets you adjust from a very short to a long trigger travel, even in the field, using almost any trigger, including stock ones
Works without modification in most V2 gearboxes in Tokyo Marui standard.
Compatible with both brushed and brushless (BLDC) motors.
Designed to work with Perun’s full range of V2 trigger accessories: Clicker V2, Clicker V2 PRO, and Speeder V2, making it the foundation of a fully custom trigger setup.
For details and exceptions please refer to the manual here.
This is the Rear Wired Version - (Deans / T-Plug Connector).

Features

Adjustable trigger sensitivity – Perun V2 Lightning offers the highest out-of-the-box trigger sensitivity of any Perun product to date. No modification to the trigger or gearbox is needed—the sensitivity can be adjusted at any time, even in the field, to suit your preference and play style.
Active brake – active brake stops the motor after each shot, preventing the spring from remaining compressed and eliminating overspin (double-shot problem) in high-ROF replicas. Braking strength is adjustable, and the brake can also be turned off entirely. Active brake and precocking settings are independent of each other.
Precocking – with precocking enabled, the piston stays in the rear position after each shot with the spring already compressed, so the next shot fires the instant you pull the trigger—a critical advantage in CQB situations. Precocking strength is adjustable and automatically adapts to the current battery voltage, so the piston always lands in the right spot regardless of your battery’s state of charge. Active brake and precocking settings are independent of each other. To release the spring safely after using precocking, switch to semi, fire one shot, and hold the trigger: a second shot with maximum active brake will fire after 3 seconds, leaving the spring uncompressed.
2-stage trigger – a light trigger pull fires in one mode; a deeper pull switches to another. Available combinations are semi–burst, semi–auto, and burst–auto.
Compatible with both traditional brushed and brushless (BLDC) motors.
Programming: All settings are configured by quick, easily memorized sequences of selector switching and trigger pulls, guided by sound signals and a multicolor LED. No tools or apps required. Settings for SEMI and AUTO are independent and can be changed in seconds, even in the field.
Safety: Low battery voltage alarm – alerts you with repeated sound signals when the battery voltage drops to a level at which it should no longer be used. The unit automatically detects the number of cells and sets the threshold accordingly. Can be disabled for non-Li-Po/Li-Ion batteries.
Diagnostic system – continuously monitors the replica and the unit itself. If a problem occurs—whether a blocked motor, overheating, short circuit, or sensor fault—the LED signals the specific issue immediately, making troubleshooting fast and straightforward.
Electronic resettable fuse – automatically cuts power in the event of a short circuit or gearbox jam, protecting both the replica and the battery. Resets when the battery is reconnected and the fault is resolved—no part replacement needed.
