FX Impact X .25 pressure level limits

I've read in the owner's manual that you risk damage to the rifle by allowing the regulator pressure drop below 100 bar and firing the rifle.

I wouldn't trust these gauges to be precise. Not just an Impact or FX issue. If you compare the Reg gauge to the fill pressure gauge to see when one drops below the other, especially as tank pressure drops. That'll give a little info. Then when you refill, compare your tank pressure to that of your fill source, that will tell you a little more. You'll have to pick which gauge to trust, I go by my fill source (large tank with a large Wikai gauge). But, specifically to your question, 100b is too little pressure for most .25 applications and at that level you are most certainly well below your reg setting. Doesn't mean you cant take a few shots off the reg but 100b is pushing it before breaking the valve stem.

As a general guideline, I wouldn't shoot much lower than the reg is set at. Chrony and target will answer that question.

Once you go below what your regulator is set at, the regulator gage will also show the same amount of air as is in the bottle. After all, the gun only has a certain amount of air in the bottle so either gage is only going to register what is available. If your bottle is showing 100 psi then the regulator is only showing 100 psi. As JDC said, the small gages used by FX in the Impact are notorious for giving the wrong pressure so I would keep that in mind. My 74 ft cf tank is always off by 3 or 4 hundred psi from what is reading on the Impact while my Marauders and Edgun and Wildcat are dead on. The EDMU in the Edgun is pretty darn precise so if it correcponds with the Omega CF tank then I am very close to the pressure readin on the gage.

Just one question, if you paid extra money to buy a gun with a regulator in it ... and you know that a regulator is there to make the extreme spread low without having to deal with a power curve … please explain your reasoning behind running the gun that far off the regulator. Just wondering.

I always fill at 150 bar. My reg. is set to 130 bar.

shoot the rifle until reg preassure equals bottle preassure.... at that moment, regulator came off and consistency says goodbye..... is that easy!

I know this is an old thread but can you clarify if your talking about the first reg or second reg. The manual is pointless and doesn’t give much detail on a tool that is quite complicated. I have my first rag at 150 second at 120. So can i shoot my gun down to 120 or 150 before refilling ? Thank you 

Generally 120 is what I've been hearing for the m3 is not to go below second reg 

Thank you, 

This whole time I have been watching the first reg and refilling. Wondering why I am only getting like 40-50 shots before fill. 

Thanks the clarification

This is an interesting question, and one I've been asking myself lately. I'm running my FX Maverick @ 170/130. With that in mind, surely one could run all the way down to 130 (or slightly above) before refilling? The manuals say that the pressure dirrerential between the two regs should be between 25 and 50 Bar, but does not state the reason. Not sure why. Running close to the bottom pressure should not give too many problems. I see someone mentioned valve damage. Could someone with more experience perhaps give us guidance in this aspect?

Thanks in advance.
