This is a complete and ready to install Electronic Trigger Unit for Rear Wired Version 3 Airsoft gearboxes, and is the beating heart of what makes G&G ETU products so unbeatable on out-of-the-box performance. The package includes an Electronic Trigger Unit, which is a computer controlled trigger that allows you to program three round burst in a matter of seconds. This smart trigger unit also has a shot sensor which can detect a complete gear cycle, leading to more precise single shot and longevity of components. Also included in the package is a MOSFET which protects the electrical components of your RIF and can detect a low voltage battery - cutting it off and stopping you from fully discharging a battery or ending up in a bad situation where your battery dies with a BB in the chamber and you are unable to remove it. The MOSFET also has a blade fuse wired in series with it. This kit comes included with a standard trigger which is compatible with the ETU to help you get the most benefits from your new trigger. This is the perfect kit for replacing a dead trigger unit in any G&G weapon, or for giving your old RIF a performance boost to bring it up to a modern spec.

Please note this unit best functions with an 11v LiPo battery. This installation is not recommended for a beginner Airsofter with limited internal parts knowledge. An 11v LiPo battery will cause strain and wear to other components considerably faster than using a 7.4 LiPo or 9.6v NiMh battery.
When installing please be extra careful when fitting the wiring, there is very little space for error. If you have 9mm bushings and bearings you may have to modify the provided selector plate. Please ensure your magazine and hop unit are empty of BBs before setting up 3-round burst or full auto cycle mode.
Due to the low voltage from different battery and/or motor specifications, it might cause an auto-semi problem. Please ensure you charge your batteries fully before use.

Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff.
Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.
We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!
Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.
Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.
