I have been using my Crown FX .25 successfully over the past few weeks (new) and just shot two pellets tonight when the air started to leak through the barrel.
I know my tank was almost full (about 200BAR) as I have a Compressor to fill it regularly. All the air leaked out actually and left the tank and barrel very cold.
I searched the site and found a similar problem so I removed the tank and reconnected…Set to cocked (without magazine) and started to pump. The air is still coming straight out of the barrel and not filling the tank!
I have sent off a support ticket to FX Airguns but haven't received a reply yet so hoping that someone can shed light on this problem.
