Upgrade your airsoft gun's performance and reliability with the G&G ETU 2.0 and Mosfet 4.0 with Vertical Trigger for Ver.II Gearbox Rear Wire. This OEM wire kit is the same as those found in the popular G&G CM16 Intermediate line, ensuring a reliable and compatible upgrade for your rifle. The Electronic Trigger Unit (ETU) provides advanced protection against trigger contact burnout, extending the lifespan of your trigger mechanism. It also allows for easy programming of firing modes, from full auto to 3-round burst, without requiring any additional tools. With the automatic shutoff feature, the ETU 2.0 and Mosfet 4.0 will power off when the battery voltage reaches a low level. This protects your battery from over-discharge and helps to preserve its lifespan. The kit includes a replaceable in-line blade fuse, allowing for quick and easy maintenance. Should the fuse blow, simply replace it with a new one to get your airsoft gun back in action. Upgrade your Ver.II Gearbox airsoft rifle with the ETU 2.0 and Mosfet 4.0 with Vertical Trigger for improved performance, reliability, and programmability. Elevate your gameplay with this essential upgrade!
