I'm noticing 18, 19, 22, and 23 are all labeled "on/off o ring"
The x valve rebuild kit on airgundesigns.com says it has "2 small on/off o rings"
I'm going to assume that the two large on/off orings are in fact in the kit.
Can someone confirm this to me before I place my order?
Many thanks for all the patience and help I've received here,
Jim
