Well I finally sucked it up and bought the Aim Trak hardware and decided to grab these guns off eBay. The guns showed up last night, I took a quick gander at them and threw them under my desk ....... didn't look too long at them. Anyway here's a picture and the buttons labled with arrows to show where there might be items not real visible in the picture.
So instead of having a hammer to reload with like my old guns these use the under method like a shotgun (labeled F).
The items marked B and C are switches while the other items are clearly buttons.
So the question for you guys is other than trigger, reload and for games like Terminator and Area 51 grenade launcher - are there any other useful things I could do with this gun?
I think the switches I just might yank out and fill in with plastic as I'm painting them anyway.
Yep - well aware of the Arcrylic Dye

Also - the guns have a directional pad - any uses for this anyone can think of?
Anyway let the ideas flow gents - thanks.
