At least I think it's called a nut... but anyways, I'm talking about the thing that holds in the 12 grams. I need a new one. I've got a fast change on my PGP, but I think my vice ruined it.
There's one on ebay now: http://cgi.ebay.com/CO2-Cartridge-Screw-Hold-Rod-Sheridan-PGP-Paintball_W0QQitemZ320071707128QQihZ011QQcategoryZ 16051QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
My question is, is this all that I need or do I also need the part that attaches into the gun?
