Yes TRA Headshot, I think I remember the Autoloader using a one pieces Trigger/Sear that pivots on a pin to actuate the Autoloaders On Off pin. The Autoloader valve is a blowforward and operates similar to an Automag.
We got a play with early prototypes (hung around with the sponsored team) and a we could do was lock them up with liquid when trying to rapid fire..... We all went over to cockers and the like :/
