This is a piston that is like a Toolies, and a Barrel-Sealing Piston. The pilot valve is smaller and can be routed anywhere on the gun, for convenient places like a trigger in my diagram. I also thought of a way to make this have a bolt but I'm pretty sure most of you can figure that out. I first thought of this design for a coaxial but it works in any layout. I later realized that its like this one, but the idea came to me before I saw this.

That won't work. The area of your little puller - unless you use a liquid and put tension on it - is way (factor of 16+ in area) too small to pull your piston off your seal.

That being said, I'm kindof surprised we don't ever see any rod based systems like this:
You would connect a piston to a rod, which goes to a piston at the back of the chamber. Simply vent behind rear piston, it pulls on the rod, which pulls the seal-piston off the seal.

Wouldn't what you just suggested be considered a Toolies piston?

WTF Dog?ou really should takl to a weapons manufacturer or someone who makes paint ball markers because that is trippy and not in a good way either.
