ASTER V2 SE Expert with Quantum Trigger - (Rear Wired)

The ASTER V2 SX Expert with Quantum Trigger is GATE's most advanced electronic trigger unit yet, engineered to push your rear-wired V2 gearbox build beyond conventional limits. Designed as a next-generation upgrade to the ASTER SE, this unit features full compatibility with brushless motors and supports up to 11.1 V LiPo batteries, making it ideal for high-performance airsoft setups. A built-in voltage boost converter allows reliable operation even with weak or heavily drained power sources, down to as low as 1.2 V during firing. With a 1 mm thick PCB and enhanced heat dissipation under heavy loads, the ASTER SX can run M200 springs and demanding configurations without overheating or failure. It also supports DSG, SSG, 19-tooth, and Infinite Torque-up gears, giving you a broad range of tuning possibilities. This model includes a free Quantum Trigger that allows precision hair-trigger programming with up to 60 levels of sensitivity in just the first millimeter of pull. Easy trigger and selector-based programming lets you set pre-cocking modes, adaptive braking, and trigger sensitivity without any cables. For even deeper control, connect via USB-Link or Blu-Link to access diagnostics, firmware updates, and expanded settings using the GCS App. The ASTER SX also features a deep sleep mode with just 0.29 mA draw to preserve battery life during downtime. Built to be future-proof and compatible with the full GATE Ecosystem, this ETU delivers lightning-fast response, mechanical lock options, and superior feedback via LED, vibration, and selector positioning. Whether you're upgrading for MILSIM realism or competitive edge, the ASTER V2 SX Expert transforms your AEG into a precision instrument built for modern airsoft warfare.
