Vulcan 3 airleak from fillprobe

Hi everybody,

Long time reader but now part of the community.

Ik just picked up a brand new AGN Vulcan 3 and went on te filling it up. Once the the fill pressure was reached I went to bleed of the air line.
Something inside the gun did not close or is sealed because the pressure was leaked out to 0.

I did try firing the gun at pressure and when Emory.
The bleed screw at the bottom is closed off.

Anybody with some advise?

Pat,
