Hello,

This is a long shot but does anybody know the o-ring size for the cap seal ( the cap that screws onto the back of the pistol and holds the co2 sparklet in place).

I've tried a few from gun shops and plumbers but nothing is really thick enough.

Mine just snapped but also deformed making it hard to measure.

Also if I manage to get the size, what material would be best.

Thank you.
