I see... So hook up your co2 tank and slap on a barrel, what are you waiting for?

Sounds like it'd work. Check out the showcase, that's actually a common way of doing it. And, check out page 13 of the Hubb Library, there's a nice example.

also what size pipe fits .22 pellets

I recommend 22 cal because you can buy a perfect barrel, albeit smoothbore, at the hardware store. 1/4" OD K&S brass has an ID of .222".

ok thanks. i went out today and my local ace only sells 1ft sections no bigger so i went to autozone and bought brake line that was just a little tiny bit off still i think it will work i aslo bought wood to make the stock. i just epoxied the barrel on and trimmed a few things i am almost done thanks again!

edit: well it appears the barrel is to big:( id wise. so ill need to buy a different one. i also found out that the hammer valve from the tippman dosent work at 150 psi. i filled the co2 tank to 150 psi with some fittings then hooked it directly to the gun via quick connect and if i hit the valve somewhat hard with a hammer it wouldent even push the pellet out of the barrel.
