FX Huma 1st reg on m3

[Gambler]

I have a "problem" that I cant adjust my 1st reg (its always bottle preassure or very low)
I tried 2 fx regs and its the same, I have read someplace here that the m3 bottle valve has a sleave or is bigger than other fx bottle valves?
And I use my crown mk2 bottle on the m3 so I think that has something to do with it not opening the valve enough if I dont turn the adjuster screw all the way out giving it max preassure.

Does this also apply to the huma 1st reg or where can I buy this sleave to put on?
I also could just buy a New 580cc bottle with m3 valve and hope that solves it, but its a bit more costy

The valve itself is sold as a stand alone part as well. You could purchase that and just swap them out. Probably Utah, cape fear or huma air would have one.

Dont i need a special tool to change the bottle valve?

Нямам ли нужда от специален инструмент за смяна на вентила на бутилката?

Yes, you need special key !!!

Yes, you need special key !!!

Never unscrew the valve of the bottle while there is air under pressure in it, empty completely before removing the valve !!! IT'S DANGEROUS !!!

Hmmm....
Ok, let me get this straight..
You have changed out the FX reg to a new one..... Also changed to a Huma Reg..(which I run, 1st and 2nd reg)
Have you checked the bottom of the hole where the 1st Reg screw in??
Remember, since you can back-fill the bottle on the gun...
There is a passage on the reg to allow fill pressure to bypass the Reg!

It is that hole on side of the reg.
So to isolated the Fill/bottle pressure is that Bottom O-ring!!
Check to see if there is any crude or scratches on the of the Hole...This where the Reg seal against!!

Good Luck
