FX Panthera Tech Question

[JackHughs]

I recently de-gassed my relatively new Panthera in order to adjust the regulator. The initial condition was de-cocked with the breech closed.

I first removed the bottle, then adjusted the regulator up de-gas the plenum. So far, so good.

I then adjusted the regulator down and reinstalled the bottle. Air then discharged from the barrel. Not good.

It appeared that the valve must be open to allow air to escape this way and maybe the hammer was resting on the valve and was holding it open. Sure enough, I cocked the rifle and the leak stopped.

My question is, is this normal behavior for the Panthera? I've de-gassed my Impact many times over the years and never encountered this issue.

Thanks

at about the 20 minute park, earnest rowe opens the bolt to pressurize it, remarking there may be preload on the hammer, pressing the valve open.

screw on bottle a little
open bolt
tighten bottle, hear plenum fill
close bolt

It's pretty common on valves that open easier or balanced type valve when all the air is emptied out the hammer spring preload can hold the valve open and sometimes they can be a pain to get them to seal up all the way when emptied they usually need a good burst of air to seal quick

Thanks to both of you. It's a relief to know that the Panthera is not malfunctioning.
