Silverback MDRX Trigger Board – Semi/Full Switch

The Silverback MDRX Trigger Board is a precision electronic control module designed for builders who demand reliability and consistency in their AEG’s trigger response and firing mode selection.

Key Features

• Hall sensor-based selector – contactless, durable switching between semi and full auto
• Microswitch-based trigger PCB – responsive, consistent actuation without mechanical wear
• Premium build quality – Silverback’s reputation for engineering excellence
• Drop-in compatibility – integrates with standard AEG gearbox configurations
• Precise trigger response – ideal for both milsim and skirmish play

Real-World Use Cases

Whether you’re upgrading a worn gearbox, building a high-performance rifle from scratch, or retrofitting a trusted platform with modern electronics, the MDRX board delivers the trigger control that separates a good AEG from a great one. Milsim operators appreciate the solid semi-auto consistency; competitive skirmishers benefit from the snappy full-auto response.

Technical Specifications

• Trigger mechanism: Microswitch-based PCB
• Selector system: Hall sensor (single/full auto)
• Compatibility: Standard AEG gearbox (V2, V3)
• Voltage: Compatible with standard 7.4–11.1V LiPo batteries

Compatibility & Upgrades

The MDRX board is engineered to work with common AEG gearbox shells and integrates with most trigger assemblies. Pair it with quality wiring, a responsive motor, and a robust spring setup for optimal performance. As an electronics module, it pairs well with precision barrels and hop-up upgrades to maximise your rifle’s potential.

UK Legal & Site Notes

This is a genuine upgrade component for your AEG – not a complete gun. Ensure your site’s chronograph check remains within limits (typically 328 fps / 1.48 J on 0.20g BBs for full-auto platforms). Always verify local and site rules before upgrades that affect trigger response or fire rate.
