GATE ASTER V2 SX Controller Set + Quantum Trigger [Rear Wired] Expert rev.2
GATE ASTER™ V2 SX Controller Set + Quantum Trigger [Rear Wired] Expert Rev.2
The GATE ASTER™ V2 SX Expert Rev.2 is a next-generation electronic trigger unit designed for demanding airsoft players seeking maximum performance, reliability and advanced customization. Developed as the successor to the ASTER SE, the SX version introduces improved hardware, full brushless motor compatibility and enhanced thermal efficiency for high-performance AEG builds.
This complete kit includes the precision-machined GATE Quantum Trigger, delivering exceptional trigger response and ultra-fine sensitivity adjustment. Designed for rear wired Version 2 gearboxes, the ASTER SX is ideal for advanced M4 and AR-platform replicas used in CQB, milsim and competitive airsoft.
Advanced Electronic Trigger Performance
The ASTER™ V2 SX offers extensive ETU customization through the trigger interface or via the GATE Control Station™ (GCS) using USB-Link or Blu-Link modules.
- Hair-trigger sensitivity adjustment with up to 60 settings on the first millimetre of movement
- Automatic pre-cocking for faster trigger response
- ETU programming via trigger, USB-Link or Blu-Link
- Firmware updates through GCS
- Ultra-low power consumption – only 0.29 mA in deep sleep mode
- Built-in voltage booster converter
- Mechanical trigger lock compatibility
Designed for High-Performance Builds
The ASTER SX Rev.2 is fully compatible with brushless motors, even when using powerful 11.1V LiPo batteries. It also supports demanding gearbox configurations and heavy spring setups.
