Hey hey hey......
Anyone (paul).
I unscrewed the back thing all the way out and took out the spring, i assume there is meant to be an O-ring between the threads on the silver disc with the two sets of threads on?
How would it affect the gun if the o-ring had been "obliterated" into a million bits and was clogging up all the thread. (I cleaned it all out and put a new o-ring in)
