The Perun ETU++ is a dedicated replacement for G&G ETU electronic board.


It enhances your trigger unit by adding many new, useful features. Simply disconnect the stock electronic board and plug in ETU++.

The stock trigger unit (switch set) is retained, so there is no need to open the gearbox.

Works with any G&G ETU replica, as well as 7.4V, 11.1V and 14.8V batteries. This does not mean your AEG can handle the voltages and increased speeds unless internally upgraded too.
