So my buddy got one of the new batch X-valves available now. He was trying to get it working on an old, pre CF frame Minimag, and at some point wanted to wanted to take off the reg end of the valve and used a rubber sleeve and some Vice grips. Long story short he scratched the hell out of the back end of the valve. My question, does anyone have some ADG X-vale back ends up for sale here? He was really bummed out and wanted to throw up over the whole thing.
