ASTER II Bluetooth® EXPERT for V2 GB + Adjustable Quantum Trigger 2 [AEG & HPA]

Unlock the full potential of your airsoft rifle with the GATE ASTER II Bluetooth® EXPERT, the next generation of Electronic Trigger Unit (ETU) and MOSFET technology for Version 2 gearboxes. Designed for players who demand exceptional trigger response, advanced customization, and rock-solid reliability, the ASTER II transforms your AEG or compatible HPA platform into a highly responsive and fully programmable system.

Featuring integrated Bluetooth® 5.2 connectivity, the ASTER II allows direct communication with the GATE Control Station (GCS) app on Android, iOS, Windows, and macOS—no additional Bluetooth module required. Configure settings, adjust trigger sensitivity, monitor diagnostics, update firmware, and fine-tune your rifle from your smartphone or computer with ease.

Included with the system is the Adjustable Quantum Trigger 2, providing both mechanical trigger travel adjustment and ultra-precise electronic tuning. With up to 680 trigger sensitivity levels, users can customize the trigger pull to suit any play style, from a light competition-style trigger to a more traditional trigger feel.

The ASTER II Bluetooth® EXPERT offers an extensive range of advanced features including programmable fire modes, burst fire, binary trigger, adjustable pre-cocking, adaptive active braking, rate of fire control, and comprehensive system diagnostics. Advanced optical sensors eliminate traditional trigger contacts, improving durability and consistency while reducing wear on internal components.

Compatible with both AEG gearboxes and single-solenoid HPA engines, the ASTER II provides exceptional flexibility for a wide variety of builds. GATE's intelligent protection systems continuously monitor battery voltage, motor performance, and controller status to help safeguard your investment and maintain peak performance.
