Perun V2 Lightning ETU (Back Wired)

Upgrade your standard mechanical trigger to a high-performance digital powerhouse. The Perun V2 Lightning is a drop-in Electronic Trigger Unit (ETU) that replaces your traditional trigger contacts, eliminating arcing and providing a crisp, instant shot every time you pull the trigger. Designed to fit most Version 2 gearboxes, this back-wired unit is the ultimate "brain" for your AEG, offering advanced programmable features without the need for external cables or complex software. It is the single most effective way to turn a sluggish rifle into a snappy, modern skirmish machine.

Key Features & Performance

• Optical & Magnetic Sensors - Replaces mechanical contacts with high-precision sensors, reducing wear and tear while increasing reliability.
• Fully Programmable Fire Modes - Easily switch between Semi, Auto, Burst (2-5 rounds), and Binary Trigger using only the selector and trigger.
• Active Braking & Pre-Cocking - Stops the motor instantly after each shot to prevent double-feeding and holds the piston back for zero-latency trigger response.
• Battery Protection & Diagnostic System - Includes a low-voltage alarm for LiPo/LiFe batteries and an LED troubleshooting system to identify gearbox jams or motor issues.
• Adjustable Trigger Sensitivity - Customise the "break" point of your trigger to suit your playstyle, from a long safety-focused pull to a "hair-trigger" for competitive play.

The "Pro" Take

The Perun V2 Lightning is the "sweet spot" of the internal upgrade world. While some units on the market are notoriously difficult to set up, the Perun is remarkably user-friendly and incredibly robust. The inclusion of "Binary Trigger" is a specific highlight - it allows a shot to fire on both the pull and the release, effectively doubling your fire rate in semi-auto mode. For those running 11.1v LiPo batteries, this unit is essential as it protects your motor and gears from the common over-spin issues found in stock setups.

UK Spec & Site Performance

In the UK, many indoor sites like The Department CQB or Driver Wood enforce strict semi-auto-only rules. The Perun V2 Lightning levels the playing field, allowing you to achieve a trigger response that rivals high-end HPA systems. By using the pre-cocking feature, you ensure that the piston is already pulled back and ready to release the moment you touch the trigger - vital for "snap-shooting" around corners in tight urban environments.

For woodland players at sites like Ambush Airsoft, the Active Braking ensures your gearbox completes a full cycle every time, even during rapid semi-auto fire. This prevents the "gearbox lock-up" that often plagues standard AEGs during intense firelights. Additionally, the unit is fully compliant with UKARA-regulated RIFs, as it does not increase the FPS/Joules of your rifle, but rather optimizes the cycle efficiency and trigger control to keep you well within site limits (typically 350 FPS on 0.20g for AEGs).
