New .25 FX Wildcat, hole in air tube-WTF!?

Received my .25 FX Wildcat yesterday evening and was beyond excited. When I went to fill it with air this morning I heard a loud hissing noise and found what appears to be a hole in the air tube! I'm perplexed as the box appeared fine and this looks like a pretty significant hole. Not sure what could have happened but it looks like its back to Airguns of Arizona! Curious to what might have caused this to happen. Any thoughts?
Bummed!



 
SpashCould it be the venting hole for the regulator?
Meaning that the regulator has a problem?


I bet your right....

Most guns have the regulator in the tube. And it looks about the right spot.

There is normally a oring on either side of that hole around the regulator and it allows the regulator to vent.

That is so that the spring stack doesn't hydro lock. A simple breather.



Most likely a simple o'ring change out. Doubt there is an issue with the regulator itself.
