FX Crown mk2 max pressure

Go off what it says on the rifle, that is typically the rifles safe working pressure.

The bottles will typically go much higher than what is printed on them. This is due to the safety margin that is needed for such a high pressure vessel. You go higher than the pressure stated on the rifle you are more than likely going to damage the internals, and very likely not be covered under any kind of warranty.

Go with the 250 and go shoot the rifle.

Hey guys,

What’s the max pressure on FX Crown MK2 (grs if that matters) ?

Seems pretty simple, fill to 250 Bar max, that is what the gun wants. Don't care if the bottle is capable of a billion Bar, don't care if the gauge goes up to 2 billion Bar, the gun is marked by the manufacturer to be filled to a Max of 250 bar. Fill to 250 Bar max.
 
Usually bigger analog gauges are more accurate than smaller ones. From a practical stand point it doeas not matter if the gauge is a few bar off on a gun.
It is more important if it is consistent. On a gun with an adjsustable regulator, I personally think the graduation marks is more important than the accuracy of the gauge. If you can read the differnce between 2-3 bar, and 5 bars, I personally do not think you need to read smaller increments than that. When tuning a gun, the chronometer should be your measuring device, and not what the gauge read.

Yes, question the Gage’s if anything out of the three, and always adhere to the manufacturers fill spec on the Gun.

This was brought up before, and someone was leaning more into filling the gun itself to 300 B just because his bottle said 300B.

It went on snd on, and my question to him was, since I don’t own an M3, just an MK2, was unless FX made the trigger block, rear block, and plenum out of thicker walled stuff, and used beefier o ring types, I’d stick to what it says in the gun
 
I RTFM, show me the line with 250 pls
I know, I was surprised I could not find it in the owner's manual either. I think that is a mistake on FX's part, it should give that specific info in the manual. But the receiver of the gun is clearly marked so that is what you should reference in my opinion.
 
maybe I'm overthinking this, maybe not. That's who I am :) I try to understand things and challenge things that are not clear to me.
Not going to apologize for that.
What if I buy a 300 BAR bottle? Actually I have 2 waiting on me, but I guess if FX says 250 BAR that's what I'm going to stick with.
Will increasing the bottle rated capacity change what the gun is designed for? No, That's your answer. It's literally etched on the gun.

Thanks mate, I agree.
I guess the manuals vary. The manual for my Impact M3, for example, very clearly states on page 9 that the “Maximum overall pressure in System: 300 Bar”. It also states “Max air reservoir pressure: See markings on air reservoir.” However, like others have noted above, the manual for the Crown MK II does not mention fill pressures anywhere. In fact the only mention of a specific pressure i could find anywhere was the warning not to set the regulator above 160 Bar.

As many have pointed out when it comes to safety and dealing with VERY high pressure it would be prudent to error on the side of caution. There are threads with pictures of injuries from faulty HPA equipment that was within specified safe operating pressure, someone literally almost lost an eye.


Using cars analogy my tires indicate they are rated for 199 mph, my car speedometer says 160mph, and the curve on the mountain road has a sign says 35mph. It is up to you which speed you decide to follow as long as you don’t hurt others.


For what it’s worth and for reasons besides safety I only fill to 220-230 bars even when the gun says 250 bars.
