The Most Advanced Drop-In MOSFET for V2 AEG Gearboxes

The Perun V2 Lightning replaces the mechanical contacts in your airsoft AEG or gel blaster with optical and magnetic sensors, eliminating moving parts entirely for unmatched reliability. With the highest out-of-the-box trigger sensitivity of any Perun product to date, native brushless (BLDC) motor support, and full compatibility with Perun's complete range of V2 trigger accessories, the V2 Lightning is the most capable drop-in MOSFET available for Tokyo Marui spec V2 gearboxes.

Fits most V2 gearboxes without modification. Compatible with brushed and brushless motors, all gearsets including DSG, and any battery from 7V to 17V. See the manual for full compatibility details.

Features:

• Brushless (BLDC) motor support
• Highest trigger sensitivity of any Perun V2 MOSFET
• Adjustable trigger sensitivity — no modifications needed, changeable in the field
• Independently programmable firing modes per selector position
• Adjustable active brake
• Adjustable precocking with automatic voltage compensation and spring release
• Binary trigger with hold-to-cancel release shot

• Electronic resettable fuse
• Multicolor LED and sound signal programming — no app, no dongle, no tools
• Compatible with Clicker V2, Clicker V2 PRO, and Speeder V2 trigger accessories

Feature Details

Brushless Motor Support

Works with both traditional brushed and brushless (BLDC) motors, making the V2 Lightning future-proof for high-performance builds.

Adjustable Trigger Sensitivity

The highest factory trigger sensitivity of any Perun product. Fully adjustable at any time without opening the gearbox — even mid-game.

Independently Programmable Firing Modes

Assign any mode (safe, semi, burst, auto, or binary) to each selector position independently. Run semi on SEMI and binary on AUTO, or any combination you prefer.

Active Brake

Stops the motor immediately after each shot, preventing spring compression and eliminating overspin-caused double shots in high-ROF builds. Braking strength is fully adjustable or can be disabled entirely. Active brake and precocking settings are fully independent.

Precocking

Keeps the piston cocked after each shot for near-instant trigger response — a decisive CQB advantage. Precocking strength is adjustable and automatically compensates for battery voltage, ensuring the piston lands correctly regardless of charge level. To safely release spring tension: switch to semi, fire one shot, and hold the trigger — a second fully braked shot fires after 3 seconds.

2-Stage Trigger

A light pull fires in one mode; a deeper pull switches to another. Available combinations: semi–burst, semi–auto, burst–auto.

Binary Trigger

Fires on both trigger pull and release for fast, easy double shots in semi-auto. Hold the trigger for 2 seconds to cancel the release shot if needed.

Rate of Fire Reduction

Reduces automatic ROF while keeping semi-auto and first burst shots at full power for crisp, consistent trigger response. Ideal for ammo conservation or realistic fire cadence.

DMR Mode

Restricts fire to semi-auto and enforces a minimum interval between shots for full DMR field compliance.

Low Battery Alarm

Automatically detects cell count and sets the voltage threshold accordingly. Repeated audible alerts when battery voltage drops to unsafe levels. Can be disabled for non-Li-Po/Li-Ion batteries.

Diagnostic System

Continuously monitors the replica and MOSFET. Instantly signals specific faults — blocked motor, overheating, short circuit, or sensor failure — via LED for fast, accurate troubleshooting.

Electronic Resettable Fuse

Automatically cuts power on short circuit or gearbox jam to protect the replica and battery. Resets on battery reconnection once the fault is resolved — no part replacement needed.

Trigger Accessories

The V2 Lightning is designed to work seamlessly with all three Perun V2 trigger accessories, letting you build the exact trigger feel your play style demands.

Clicker V2

Adds a tactile trigger break similar to a real firearm — a clean, defined wall to push through before the shot fires, for improved realism and control.

Clicker V2 PRO

Five individual adjustments and a stronger break for the most authentic trigger feel an airsoft replica can offer. Built for serious realism enthusiasts.

Speeder V2

Fully adjustable overtravel, pretravel, spring tension, and break (including zero break) for the fastest, most consistent trigger possible. Built for speedsoft and CQB.

Installation & Compatibility

Includes a proprietary selector plate for direct fit in most AR-type replicas. Non-standard selector plates are covered by an included magnet, double-sided tape, and positioning tool — no permanent modifications required. The magnetic Hall-effect selector sensor is completely unaffected by ambient light, making it fully compatible with cut-out receivers.

Compatible with all gearsets including DSG, brushed and brushless motors, and any battery from 7V to 17V.

No App. No Dongle. No Tools.

All settings are programmed via simple, memorable sequences of selector switches and trigger pulls, guided by sound signals and a multicolor LED. Every setting is independent per selector position — changeable in seconds, even under fire.
