Hey fellas, I just installed my hum air regulator last night for an fx impact m4 and I can't seem to get pressure on the regulator side of rifle just yet.... Any opinions or thoughts would be appreciated.
Just installed extra high power huma regulator on my fx impact m4 - NO PRESSURE ON REG SIDE OF GUN
- Thread starter dnye1986
- Start date
Huma just told me I may have received one of their faulty regs that do not have a hole in them.... I've had the set screw at many different locations with absolutely no pressure reading in the gun whatsoever

Have you ever seen one that read no pressure upon install? Like absolute zero? And do you think that lube could have created a seal??

I have seen huma and fx reg showing no pressure when installed. That's only cause screw is turned in too much and stopped the pressure going into the gun. If back out the screw pressure will climb up. If you back out the set screw until it's flush with the reg body and still no pressure. Your washer could be stacked wrong. I once stacked them wrong and no matter what the pressure always show 0. Check your washers, they must be stack correctly. Read the manual, huma should have their manual in their site. I have never heard of a reg with no hole. Just look at your reg for the hole then. Should have 1 single hole in the middle. Easy to spot the hole. As for using lube, I apply lube and wipe it away leaving just a tiny coat over it. You don't need much lube.

I don't know if it's possible with a Huma on other guns....but guys reinstall them backwards after a rebuild on my guns all the time. They don't pass any air backwards.

Try loosening the gauge. If you tighten the gauge too much it's not going to read pressure.

Thank you. Yeah they said they thought they pulled them all from sales inventory but they may still be out there. And they said it's the set screw that may not have a hole in it

The hole on the set screw in the reg, is it just the little ones on the side or should there be a hole in the end of the set screw?

Looking for more feedback please anybody out there, I decided to install my old reg to see if there is a massive leak around it, as there is now around my new huma regulator. First absolutely registering no pressure in the gun. Now today I try and reinstall it and it has a major air breech around the reg. Any thoughts or suggestions would be most appreciated. OLD INSTALLED PERFECTLY NO LEAKING! huma has a massive leak around reg......

You will have to check the o-rings for damage. Also check the threads to make sure that they're not damaged.
If you don't mind me asking , what are you trying to achieve that you want extra high output for?

My advice is, if you having hard time with your fx impact..send it to utahairgun. They are the official FX now. They will know what to do and fix it. Sometime it's best to have a professional do the job instead of messing with it and creating more problems than it should.

I'm trying to achieve extra high output. I want to see how many fpe I can get with slugs and still keep accuracy

This was my first thought. I have also received a faulty part from them. Once I contacted them they sent the correct part promptly.

Yeah they've been really cool so far man. From what I've read and in my experience thus far, this new .35 M4 stock is at least 40 fps more powerful than the stock m3, and with theae upgrades I think it possible to fly these 93 grain slugs close to 1000fps. If it can be done I'd like to do it.

Sure seems like the Huma is faulty. I would send it back and use the stock one until a replacement. You might find out it shoots fine with it.

I've finally been able to unlock 170 bar with the upgrades. The stock hammer and spring won't improve fps past 140-145 bar in my particular gun.
