I recommend degassing all airguns before service, if gun is more than 2 years old, and if you’re going to replace an oring consider replacing all of them.

The OEM HW cylinder won't dump air. The aftermarket cylinder will, at least mine does.
Number 2658 is probably the cause, or course the other oring in red are likely. Pretty easy rifle to rebuild.
