You left out a piece.  If nothing caps the gas entering the gun, the spring 
will never recock the gun for the next shot.  

If you want to build a home-brew gun, I say go for it.  Practices like this are 
the same explorative building that has created C6C and several other now battle 
tested technologies.  Hobbies strike different people in different ways.  Some 
people build because they love to build.  To others, building is just the 
prerequisite for battle.  If you have fun doing it, who can say you did it 
wrong.

Ryan,

I don't quite understand the mechanism you described. How does the spring 
device seal the chamber?

I read about a fairly simple gun design that you might be interested in trying. 
Attached is a scan of a representation I drew. The gas enters from a valve into 
the gun, filling up the space behind the bolt. The bolt then rushes forward 
(compressing the spring) until it runs off of the rear piece. This allows the 
gas to flow through the bolt, propelling a single paintball forward. Once the 
gas stops, the spring returns the bolt, loading the next paintball. Any ideas?
