Hi Max-u52, can't as I'm at work at the moment. The newer airsoft units have the microswitch fitted and it's a real bummer that I have to fit this. I think I'll have to swap the unit out and modify it to fit the tank. I don't like doing this as the gun shoots really well at the moment and as soon as you take these things apart, they are never as good again. That's what annoyed me about the Clark website, it assumes you have the microswitch type airsoft unit which if you are upgrading an older model with one of their boards, the chances are you wont have this fitted.
Cheers
