All that would need to be done is a cannister of propane at the end of the grip, when the grip is pumped forward, it hits the top of the propane cannister and squirts a small dose of propane into the chamber. Simple as..
That is how the Tippmann propane marker works. The only thing is that a regulator and metering system needs to be incorporated. It would be a good design for a pump action.

My recent combustion is in the cannon showcase now.

I'm going to the University of New Haven in Connecticut.

Also, I understood what you were saying maxus, it is extremely similar to the Tippman C3. Instead of a direct contact with the tank, the amount is measured. It still requires pump action. I think Tippmann is having the same problem we are, or they would have made a semi combustion by know don't ya think?
