Processor trigger unit PERUN V3 Integrated

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.

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.

• Brushless motor support
• Binary trigger
• DMR mode
• Rate of fire reduction

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.

Features

• 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.

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-BOY, 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.
