ASTER is a younger brother of our famous high-end TITAN ETU, designed to give you a tactical advantage at an attractive price. Our 4th generation Control System will give you maximum reliability and protection together with tons of useful functions such as binary trigger, burst mode, active brake and other essentials. One of the biggest advantages of ASTER V3 is the optical trigger sensor - the same as in TITAN V3! Gain a unique tactical advantage thanks to extremely fast trigger response - up to 6 milliseconds! Give your AEG a new lease of life!

ASTER V3™ will transform your AEG with V3 gearbox into computerized training weapon system equipped with optical sensors instead of mechanical switches, which can be prone to faults. With additional dongle it enables you to adjust the trigger sensitivity with military precision. Innovative proximity trigger sensor offers up to 315 different sensitivity settings.

Thanks to our built-in technology, you choose how to configure ASTER. Do you need a quick change in settings on the battlefield? You can do it via trigger. If you prefer full control and visual interface, connect your replica via USB-Link or Blu-Link dongles with our GCS App. To enjoy full potential of ASTER, you can upgrade its firmware to ADVANCED or EXPERT version.

Take the next step and gain additional functions with ADVANCED and EXPERT upgrades. Enjoy access to main ETU statistics and measurements, precise ROF control, all fire modes such as customizable burst, semi ramping, burst/auto on one mode, equalizer, sniper delay and many other extremely useful functions - everything to prepare for the most demanding mission.

Optical sensors

ASTER V3 is equipped with well-known and tested optical trigger sensor, the same as in TITAN V3, optical sensors detecting gear cam and selector positions. With the GCS App, you can easily calibrate, test and adjust all sensors.


Selector switching point adjustment

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

Trigger sensitivity adjustment

The trigger sensor offers you even 315 possible sensitivity settings. You do not have to disassemble your replica. 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. Additionally, by upgrading firmware to ADVANCED or EXPERT version, you can even use equalizer mode. Thanks to this option, you don't need to fully release the trigger to fire the next shot. This option is really useful when the trigger sensitivity level is very high. The gen. 2 proximity trigger sensor offers the following sensitivity ranges, depending on trigger construction:


In total: 103–315 levels


In the first millimeter of trigger movement: 1–38 levels
