Perun V3 Hybrid Trigger Unit

Perun V3 Hybrid Drop-in MOSFET – Advanced Programmable ETU for V3 Gearboxes

Upgrade your AK-style airsoft AEG or gel blaster with the Perun V3 Hybrid MOSFET, a powerful and affordable drop-in electronic trigger unit designed specifically for Tokyo Marui standard V3 gearboxes. This hybrid solution combines optical and magnetic sensors to eliminate unreliable mechanical contacts, delivering superior reliability, lightning-fast response, and extensive customisation options. Perfect for CQB, DMR builds, high-ROF speedsoft setups, or realistic AK replicas, the Perun V3 Hybrid drop-in MOSFET transforms your V3 gearbox into a modern, high-performance electronic system.

Hybrid Sensor Technology for Maximum Reliability

The Perun V3 Hybrid uses a smart combination of optical sensors (for precise sector gear detection, including DSG compatibility) and magnetic sensors (for trigger and selector detection). This hybrid design removes most moving parts prone to wear and damage, ensuring flawless operation even in extreme high-stress configurations. It works with virtually any trigger, selector plate, and gear setup without permanent modifications.

Adjustable Trigger Sensitivity – 5 Levels, Field-Adjustable

One of the standout features is the highly flexible trigger control. Choose from 5 sensitivity levels ranging from an ultra-short pull (ideal for competitive speedsoft) to a long, stock-like travel. Adjust the trigger sensitivity quickly during gameplay using simple selector and trigger sequences—no tools, no disassembly, and no trigger modifications required. This makes the Perun V3 Hybrid MOSFET incredibly versatile for any play style.

Packed with Essential Airsoft Features

• Active Brake — Instantly stops the motor after each shot to prevent overspin, double-feeding, and unwanted spring compression. Essential for high-rate-of-fire builds.
• Pre-cocking — Keeps the piston pre-tensioned for near-instant trigger response, giving you a crucial edge in CQB. Release the spring safely by pulling and holding the trigger for 2 seconds (fires a second shot without pre-cocking and fully braked).
• Fully Programmable Firing Modes — Independently set SEMI, BURST (2–5 rounds), or FULL-AUTO for each selector position (except SAFE). Configure your replica exactly as you want.
• Binary Trigger — Fire on both pull and release for rapid double taps in semi mode. Supports combinations like semi → burst or semi → auto.
• Rate of Fire Reduction — Lower the ROF in auto or burst modes (useful for ammo conservation or realism) while keeping the first shot crisp.
• DMR Mode — Add mandatory intervals between semi shots to comply with field rules.
• DSG Mode — Special sector gear detection optimised for dual-sector gears.
• 2-Stage Trigger Option — Light pull for one mode, deeper pull for another.

Robust Protections and Diagnostics

The Perun V3 Hybrid includes multiple safety systems:

• Electronic resettable fuse (protects against shorts and gearbox jams)
• Low-voltage battery alarm for Li-Po and Li-Ion packs
• Built-in diagnostic system that monitors for issues and alerts you via sound and LED (jams, overheating, sensor faults, etc.)

It supports batteries from 7V to 17V and handles any spring rating without limitations, making it ideal for both stock and heavily upgraded extreme builds.

Easy On-the-Field Programming

No apps, no computers, no complicated menus. All settings are adjusted using quick sequences of fire selector movements and trigger pulls. Clear audio beeps and a multicolour LED provide instant feedback, so you can reprogram in seconds, even under fire. Factory defaults are well-balanced, and you can reset everything easily.

Compatibility and Installation

The Perun V3 Hybrid MOSFET is a true drop-in unit for most standard Tokyo Marui V3 gearboxes (including many Specna Arms, E&L, LCT, and other AK platforms). It fits without major modifications in the vast majority of cases. Available in universal wiring versions (standard or DE variant) for flexible installation. It supports both brushed and high-performance motors.

Note: Always check the official manual for specific gearbox exceptions.
