Core Zx Problem

[MovingTarget]

Hi guys,

Bit of a strange question for you.
I just bought a Core ZX 2003 pistol and have a problem with it.

I cock the gun, and insert the CO2 cartridge, then screw the cap on tightly.
At this point all seems well, but after firing 6 - 10 rounds, the cap somehow manages to unscrew itself part way, which empties the whole cartridge.

This seems to happen no matter how much I tighten it.

Is this a common problem, and if so, how could I fix it?

Thanks so much for your help everyone!

I don't know about the cap, maybe some thread locker? But you don't get more than like 15 shots off a 12 gram anyway, so I wouldn't be so sure that there's anything wrong.

try putting an o ring on the cap to prevent it unscrewing
