Programmable Trigger Unit | Nebula II | Rear Wired | Zion Arms

This trigger unit is an advanced electronic trigger system for AEG replicas with V2 gearboxes. The Nebula II replaces the mechanical contact points in your gearbox with optical and electronic detection, providing faster response and extensive control over firing modes. The heart of this airsoft trigger unit consists of a programmable MOSFET with integrated protection against overvoltage, undervoltage and motor faults.

Technical characteristics

The unit features a distinctive purple circuit board with high-quality electronic components. The system works with both optical and mechanical sensors for trigger detection. The T-Dean connector ensures reliable current transfer. The package contains the MOSFET unit, a special trigger, selector plate and rear wiring configuration with pre-assembled wiring. The unit is fully compatible with brushless motors and offers active braking function to stop the motor immediately after firing.

Compatibility and application

This trigger unit is specifically designed for V2 gearboxes in M4, M16 and AR15 platform replicas. Installation requires technical experience as you must replace the original trigger contacts. Thanks to the built-in programmer you can choose from different firing modes: semi-auto, full-auto, 3- or 5-round burst, binary mode and sniper mode. Pre-cocking is programmable for optimal response. This upgrade suits both CQB builds where fast semi-auto response is important, as well as DMR setups where consistent trigger response is crucial.
