[Chase the Gr8]

I've got my nephew into the sport, so I figure it is time that he has his own gat. I have a pm07 that I've had laying around for some time that I want to hand down to him.

The only issue is that when I cut on the ASA, air leaks straight through the barrel. I have replaced ALL of the orings in the bolt, and the solenoid is pretty much new.

Anyone have any troubleshooting ideas for me to solve this issue?
