Does anyone know what would cause the gun not to fill to 300 bar? I have tried to fill it with a 6.8L tank as well as a compressor and it only takes air till about 275 bar. Weird thing is that the compressor keeps pumping but both the gun gauge and compressor gauge show the same pressure. I would think if the gun stopped taking air at 275 bar, the compressor would build pressure until it hit the shutoff. Air must be going somewhere for the compressor to keep working but not building pressure and the compressor isn't faulty. Any ideas?
FX Kalibrgun Cricket 2 Tactical not filling to 300 bar
- Thread starter jskd82
- Start date
The cricket lineup has a restricted air flow for when it is getting filled. The higher the pressure in the bottle, the more constricted that air flow gets. I've never been able to fill mine past 290. My friend has 2 crickets. One doesn't go above 260. The other one gets to about 280.

1. What JaceSpace1369 says : "restricted air flow ". I consider it a kind of 'free filling-safety'.
2. Nevertheless, guess never a bad idea to check wether your gauge is still working as it should (displaying the actual pressure)
Don t own bottle-Kalibrguns myself, only tubes. But the restricted fill flow is the same.
Because I initially couldn't much appreciate the slow filling of my Kalibrguns, I repeatedly -trial and error-like- adjusted the screw in the fill valve. Somewhat later found out that, when turning the screw in the fill valve even by a mere millimeter to far, the gun starts leaking there (at least with tube-Crickets that is). Today my Crickets fill 'acceptably slowly', so slightly less slowly than before.
Maximum filling pressure i ve ever applied was 280 bar.
No problem for me there, for my Crickets only start shooting consistently from 250 bar anyway.

Don't worry about MAX numbers! MAX fill, MAX velocity, etc. Because something CAN be filled to X number DOESN'T mean it's MOST EFFICIENT at that MAX number!!! Look for MAX EFFICIENCY & stop worrying about posted MAXIMUMS

Yes, it's there to as a safety measure and to prevent your bottle from over heating and expanding to quickly. It can also be adjusted though. The adjustment is minor from what I have heard but it can be done.

Totally agree. Trying to fill and tune your gun to the ragged edge of its engineered specs is a recipe for part failures.

I fill mine to about 250 or 260 where it seems to settle out. The shot count is so high that I don't worry about it any more than that.

If there is nothing wrong with the compressor AND it never shuts off, that air has to be leaking somewhere.
I agree there is no reason to go to max if you don’t have to but if a vessel is designed for 300bar, it’s not hurting a thing and decreases shots per fill. It sounds like a design flaw that won’t let you reach what the gun claims it is capable of.

Wowzer! If you refill at 200 your compressor/pump has a stressful life … as well as your Cricket’s air bottle’s O-rings.

There is always the chance that your compressor has enough wear that the final stage alows blow by at that pressure. Wouldn't hurt to put a stop in your output Foster fitting and see if the pressure can reach 300 bar.
