pneumatic pop off valve

[rossunger]

Did anyone receive a pneumatic pop off valve in their kit of parts?

It was a First choice item. I don't think it was in the KOP. You can confirm that by looking at the KOP inventory list on the First web site. You need the valve specified by rule. Andymark has them.
Last check, they are still available as a First Choice item if you have any credits left.
