Perun V3 Integrated mosfet combines the full range of functions known from Perun’s latest electronic trigger units with an integrated, adjustable Clicker. The Clicker creates a clear trigger wall and tactile break without requiring a separate accessory.

Its ball-bearing-supported lever provides a clean, crisp and snappy break at stronger settings, while maintaining smooth, consistent and responsive trigger movement when the break is set light or removed completely.

Selector calibration compensates for small differences in the position of the selector plate insert, making installation more forgiving. A standard installation requires no soldering. Two sets of wire extensions support common Version 3 gearbox layouts, while optional solder pads can be used for a tracer or gel-blaster magazine connection.

Feature Descriptions

Brushless Motor Support
Compatible with both traditional brushed and brushless (BLDC) motors. When using a brushless motor, follow the motor manufacturer’s recommendations concerning active brake and PWM-based rate-of-fire reduction.

Adjustable Trigger Sensitivity
Trigger sensitivity can be adjusted electronically at any time, including in the field, to suit the user’s preferences and playing style. No permanent trigger modification is required.

Independently Programmable Firing Modes
Program each selector position (SEMI and AUTO) independently as SAFE, semi-automatic, burst, automatic, or binary. For example, SEMI can remain semi-automatic while AUTO is configured as binary.

Active Brake
Active brake stops the motor after each shot, prevents the spring from remaining compressed, and eliminates overspin—the double-shot problem found in some high-ROF replicas. Braking strength is adjustable, and active brake can also be disabled completely. Active brake and pre-cocking settings are independent.

Pre-cocking
With pre-cocking enabled, the piston remains in the rear position after each shot with the spring already compressed, so the next shot is fired as soon as the trigger is pulled. Pre-cocking strength is adjustable and automatically adapts to battery voltage. To release the spring safely, select SEMI, fire one shot, and keep the trigger held; after 3 seconds, a second shot is fired with maximum active brake, leaving the spring uncompressed.

2-Stage Trigger
A light trigger pull fires in one mode, while a deeper pull activates another. Available combinations are semi-automatic–burst, semi-automatic–automatic, and burst–automatic.

Binary Trigger
A shot is fired both when the trigger is pulled and when it is released, making rapid pairs easy in semi-automatic fire. Hold the trigger for 2 seconds to cancel the release shot when necessary.

Rate of Fire Reduction
Reduces the rate of automatic fire. Semi-automatic shots and the first shot in each burst are always fired without power reduction to preserve a crisp trigger response. This is useful for conserving ammunition or achieving a more realistic cadence.

DMR Mode
Restricts the replica to semi-automatic fire and enforces a minimum interval between shots. Designed for fields that apply DMR rules.

Low Battery Voltage Alarm
Repeated sound signals warn when battery voltage falls to a level at which the battery should no longer be used. The unit automatically detects the number of cells and sets the threshold accordingly. The function can be disabled for batteries other than Li-Po or Li-Ion.

Diagnostic System
Continuously monitors the replica and the unit itself. If a problem occurs—such as a gearbox jam, overheating, short circuit, or sensor fault—the LED identifies the specific issue, 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. It resets after the battery is reconnected and the fault is removed, so no fuse element needs to be replaced.

Integrated Clicker
The integrated Clicker introduces a tactile trigger wall and break similar to the feel of a firearm trigger. Its magnetic mechanism is highly resistant to wear, while the Clicker lever runs on ball bearings for precise and predictable movement. Trigger break force, pretravel, and overtravel can be adjusted to match the user’s preferences. With a stronger break setting, the ball-bearing-supported lever helps produce a clean, crisp and snappy trigger break. The break can also be set for a light, microswitch-like feel or removed completely. In these configurations, the ball bearings provide smooth, consistent and responsive trigger movement, helping the trigger return and move in a predictable way while maintaining stable sensor readings. This allows the same trigger mechanism to be configured for very different applications—from a heavier, tactile and realistic trigger break to a fast, low-resistance trigger suited for rapid semi-automatic fire.

Compatibility and Installation
Designed for Version 3 gearboxes built to the Tokyo Marui standard. Perun V3 Integrated has been successfully tested in compatible gearboxes from Arcturus, D BOYI, CYMA, E&L, G&G, ICS, JG, LCT, and Snow Wolf. Minor fitting may be required in Retro Arms gearboxes, and production-batch differences can occasionally affect compatibility.
Compatible with stock and aftermarket Tokyo Marui-standard Version 3 triggers, brushed and brushless motors, all common gearsets—including DSG, TSG, short-stroked, helical, and non-helical sets—and power sources from 7 V to 17 V.
The white selector plate insert is placed close to the optical sensors and then calibrated. Because calibration compensates for small placement differences, the insert does not have to be glued at one perfectly exact point.

Programming
All settings are configured using quick, easy-to-remember sequences of selector movements and trigger pulls, guided by sound signals and a multicolor LED. No tools or apps are required. Settings for SEMI and AUTO are independent and can be changed in seconds, even in the field.
