Can you replace the ETU in an ARP9

[AirSniper]

I am looking at a G&G ARP9 on the sly for my lad and need to know if I can just change the ETU in it for a Perun ETU++ and if so, what type of ETU is it? A board like the ETU++ or a trigger unit that replaces the inner guts of the trigger?

The G&G ETU is a trigger unit and a board; you can swap the board part of it for the Perun ETU++.

The G&G ETU is external to the gearbox, so the Perun ETU++ is an easy swap. It's form is slightly smaller than the G&G one and gives you a load of extra features.
