Programmable Trigger Unit | Zion Arms

This trigger unit from Zion Arms is an electronic trigger unit (ETU) that gives you complete control over the firing modes of your AEG. The component replaces the standard trigger contacts in your Version 2 gearbox and makes it possible to fully customise your fire control settings. You choose this airsoft trigger upgrade when you want more flexibility in your firing 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 is supplied with a sector gear equipped with optical sensors. The system works with a USB connection for programming and has pre-wired cabling with T-plug connector. The ETU requires an 11.1V LiPo battery for correct operation. The finish is matt black with clearly visible Zion Arms branding on the circuit board.

Compatibility and application

This trigger unit fits in 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 dismantling your gearbox and replacing the original trigger contacts, so some technical experience is advisable. The system is intended for advanced builds where customisable firing modes are desired.
