FX FX M3 .22 leak

[90mph]

My apologies if I missed this specific leak discussion.
I can charge my M3 to 250 Bar and within a few days, the bottle pressure gauge and the first regulator gauge show 160 bar and the second regulator gauge reads 90 bar. I've used leak detector on all the usual suspects but no bubbles. Any help/suggestions would be appreciated. TIA

Turn the gun upside down and check the atmosphere hole in the first reg.

Here are three YouTube videos dealing with the FX Impact M3 leak detection and repair:
1)

2)

3)

Atached is a schematic and parts list from FX for the Impact M3

I suggest you watch the videos and keep the schematic on hand as you look for and proceed to replace O-rings. I just finished rebuilding and making many modifications to my Impact MK2. The hardest part was getting over the fear of taking apart my rifle. It isn't that difficult and if you are determined you can get the job done. Good luck.

Is your 1st reg set to 160 bar?

Is your 1st reg set to 160 bar?

Yes, so if the bottle is leaking, why does it stop at 160?

Weird as if it drops nearly 100 bar that fast it shouldn’t be terribly hard to find the leak. Like @Vetmx said check the tiny vent holes for the regs. In my experience the amp reg is the first place to check and find a failure. Have you tried a balloon over the barrel to test for a valve leak ?
