I'm considering using a 10 oz paintball Co2 tank as a chamber for my in-the-works qev marble gun. I removed the pin valve, but I can't seem to find the thread size of the actual cylinder anywhere! If anyone knows the thread size, please tell me! I need help!

No. CGA 320 is the the thread size for the outlet threads (ASA).
That adapter screws into a bottom line. I need to know the threads of the actual cylinder...

you could build a sweet hybrid with one of thoose bottles that or if u make a pnumatic run it off unreged scuba air thoose c02 tanks are made to hold 3k psi at least cause the burst disk on the pin valve pops at 3k

A co2 container would make an excellent chamber for a hybrid spudthug.
Why wouldn't it?

The size is 1/2" BSP or the British national pipe thread. We use BSP fittings here, not NPT. 8)

you would make a hybrid from a co2 tank because it could probably take a 50x mix without blowing up and using unregged scuba in a gun with a metal chamber rated to 3kpsi is not stupid seeing a completly full to the brim scuba tank is only 3k psi
