ASTER V2 SE raises the price-performance ratio including in the set Quantum Trigger and new functions programmable via trigger. Now, out-of-the-box, you can set sensitivity from ludicrous ‘touch’ through ‘hair’ to full movement. Improved programming via trigger gives you new settings like automatical pre-cocking (LOW, MID, HIGH), trigger sensitivity adjustment, active brake settings with top-class adaptive mode and new SAFE - SEMI - BINARY selector mode. Calibration, DTC codes - all available just via trigger and selector movement. Additionally, you get brushless motor support and new noise-resistant trigger detection algorithm. ASTER's smart fuse protects your AEG’s battery, motor and the controller, even in case of reverse battery connection. This feature, along with the optical sensors, makes ASTER SE one of the most durable ETU on the market. 


ASTER is not just regular ETU/EFCS mosfet. It is the complex system that turns your AEG into future-proof advanced training system. You choose how to configure ASTER – simply via trigger or through USB-Link / Blu-Link and our advanced GCS App. You can ask your technician or borrow from friend very popular USB-Link or Blu-Link and use GCS app to update ASTERs firmware, carry out diagnostics or change settings in a very convenient way. If you like it you can get your own Blu-Link and use Smartwatch app, giving you real-time data to reinforce your tactical decisions.

What makes ASTER V2 SE so special?

  • Everything you need out-of-the-box
  • Quantum Trigger included in the kit
  • No need to use USB-Link for installation and configuration
  • New noise-resistant trigger detection algorithm
  • Hair-trigger out-of-the box. Even 60 trigger sensitivities for the 1st mm (0.04 in) of movement
  • Additional protection against interferences thanks to multi-layer PCB with EMC shield
  • Automatical pre-cocking: LOW / MID / HIGH
  • Compatibility with brushless motors
  • Trigger sensitivity adjustment without any limitation
  • Improved cycle detection
  • Active brake adjustment: Adaptive / 100% / 60% / Brushless motor / OFF
  • New selector mode: SAFE - SEMI - BINARY instead of SAFE - BINARY - AUTO
  • GCS App allows for making firmware updates via the internet, which enables quick applying of improvements

What distinguishes ASTER V2 SE from the competition?

  • ASTER gives you great flexibility and is future-proof. Today you can program the most important functions with the trigger, and tomorrow you can borrow a USB-Link or Blu-Link from a friend to configure advanced functions, perform a firmware update, run diagnostics or use the GCS app on a smartwatch
  • Hair-trigger - up to 60 sensitivity in the first millimeter of trigger movement
  • Top-notch automatical pre-cocking
  • ASTER is resistant to reverse polarity
  • You can update its firmware via the Internet
  • ASTER is a part of GATE Advanced Weapon Ecosystem
  • Lowest in the market current consumption. Deep sleep mode with only 0.29 mA current consumption prevents battery discharge
  • Built-in voltage boost converter allows for trouble-free operation with weaker batteries and increases the switching efficiency
  • 3.75V ready - it operates at very low voltage (even 1.2V during the shot), which is important in high-tuned AEGs, where the voltage under load drops significantly
  • Sensor that supports Infinite Torque-up, DSG, SSG, 19-tooth and standard gears
  • The possibility of using a mechanical trigger lock
  • Compatibility with brushless motors

  • Optical sensors

    ASTER has optical sensors for detecting gear cam, trigger and selector position.

    Trigger sensitivity adjustment

    The trigger sensor offers you even 470 possible sensitivity settings. You do not have to disassemble your AEG. Just use GCS App to adjust the trigger to your preferences and level of skills. You can even activate 2-stage trigger and set two different trigger sensitivities. Pulling the trigger slightly produces Semi or Burst fire and pulling the trigger further produces Burst, Burst / Auto or Auto fire. The 1.5 gen. proximity trigger sensor offers the following sensitivity ranges, depending on trigger construction:

    In total: 160–470 levelsIn the first millimeter of trigger movement: 3–60 levelsSelector switching point adjustment

    The selector sensor gives you an option for fine calibration of selector switching point.

    Please note: Selector switching point cannot be set while programming via trigger.
