felex- no problem and thanks.

the black skater- The ammo doesnt go into the valve, it drops into the barrel. The pink thing is a tee. There is a tee inside of a bigger tee. You neest to cut the barrel into two pieces and re-join them with the tee. The piston works off of pressure differences. There is more pressure behind the piston than infront of it because there is no pressure in the barrel, the piston automaticly wants to go foward but is blocked by the barrel, which creates an airtight seal and doesnt let any air in the barrel. To fire the gun you release the pressure behind the piston, which means there is now air infront, but not in the back. This air forces the piston back and lets the air out though the barrel and fires the paintball/marble. The air goes out almost instantly, which is why it only fires once before you repressurize the chamber. While you are refilling another ball drops into the barrel. Now evrything you read in the last minute or so will happen in about 1 second in the gun, meaning you can take about 1 shot per second. Did this answer your question?

You are wrong, very very wrong. the piston seals against the barrel and has a piece of rubber bolted on it to help seal it. http://www.spudfiles.com/forums/viewtopic.php?t=260 Hopefully this will save me 1000 words.

I don't get your question really.

The only thing that needs to be sealed is between the barrel and the piston with some neoprene or rubber. Also I guess on the outside of the piston so too much air doesn't get around it. The projectile can be whatever you want.

Is that what you mean?
