Programmable Trigger Unit | Zion Arms – for your replica

This trigger unit from Zion Arms is an electronic trigger unit (ETU) that gives you full control over the fire modes of your AEG. The component replaces the standard trigger contacts in your Version 2 gearbox and allows you to fully customise your fire control. You choose this airsoft trigger upgrade when you want more flexibility in your fire modes or when you want to improve your trigger response by switching to an electronic system.

Technical specifications

The unit consists of a black circuit board with integrated electronics and comes with a sector gear equipped with optical sensors. The system operates with a USB connection for programming and features pre-installed wiring with a T-plug connector. The ETU requires an 11.1V LiPo battery for correct operation. The finish is matte black with clearly visible Zion Arms branding on the circuit board.

Compatibility and application

This trigger unit fits M4/M16 Version 2 gearboxes from Zion Arms, G&G, KWA, VFC, E&L, Arcturus and Lancer Tactical. You can choose between semi-auto, various burst modes (2, 3, 4 or 5 shots) and full-auto. Installation requires disassembly of your gearbox and replacement of the original trigger contacts, so some technical experience is recommended. The system is intended for advanced builds where customisable fire modes are desired.
