Gauntlet air tank positioning
« on: January 03, 2019, 04:25:47 PM »
Cancelled an order for the .25 Gauntlet and ordered the .22 Gauntlet. I'm sure there has been a topic on the way the pressure guage and fill fitting does not line up with the slots in the fore stock when the tank is screwed in all the way. I would like some ideas on how to correct this situation without damaging the stock. Any ideas??

I suspect, you could use a washer. The o-ring seal is not on the surface which mates with the tube the air tank screws into, but rather on its nose as it were.

One would think UMAREX would fix this before they get a bad reputation. But considering their other manufacturing foibles, I'm not so sure.

I have an Omega compressor. If you're a fellow Guild member, and you pass through Roswell, NM, I'll fill your portable tank as a courtesy.

I should probably call their tech support and see what they suggest I do. They sent it with the tank loose. With the tank screwed in tight, the pressure guage and air connector is at 10/4 position or 11/5 position when looking at it from the muzzle. I would've thought that they would have tighter quality control on their product. I did try a couple of washers to see if it made any difference. Not much change.

They probably don't make the regulator.... Regs generally don't have to tighten in any particular position, so the reg. manufacturer doesn't care about thread clocking.... You can get plastic "pop-on" shims from Ninja that go between the bonnet and the tank block, so that the tank tightens up where you want it to....

Realistically, it doesn't matter, because the bottle is in side the stock, and when there is air pressure in the gun the bonnet of the regulator is pushed forward in the threads in the tank block, and gets quite rigid.... It no longer rattles around loose.... I would just run it in tight, then back it off until the gauge and fill fitting are where you need them, then fill the bottle.... I think you will be surprised how rigid it feels once pressurized.... and with the stock over it, you probably can't tell anyways....

Thanks Bob. I'll give that a try. I've never dealt with bottles before. Always thought they had to be tight to be safe.

The O-ring is inboard of the threads.... There is plenty of thread depth, even if you back the bottle out 1/2 - 3/4 turn.... Once there is pressure inboard of the O-ring, the bottle is forced forward in the tank block and the threads take up the load.... It really gets quite rigid....

Okay....so I positioned the tank where I wanted it and put a little less than 1000 psi in the tank. :) Yep, the tank got rigid and didn't move. Will see how it does this weekend. Thanks again for the replies and suggestions.  :) :)

When I received my Gauntlet from PA I also quested the tank not tighten on the threads.  I contacted
PA's repair department and was informed that under-pressure the tank will stay in place.  I accepted
their advise and have not had any issues with leakage or the pressurized tank moving.  I read that Ninga
supplied the tank and regulator for the Gauntlet.  The small pressure gauge on the Gauntlet's tank has
Ninga's id mark.

Okay....somewhere I read that the bonnet on the regulator on the Gauntlet air tank could be adjusted so that the threads could be completely seated and the guage and fill nipple be in the correct position. There are 2 set screws on the side of the bonnet and if you screw the bottle in until it's seated, you can then loosen the set screws and rotate the bottle and regulator to where the guage and fill nipple are easily fillable and seen. Just make sure you re-tighten the set screws !

That is not a recommended procedure, the bonnet is supposed to be seated against the regulator body.... I'm betting Ninja would tell you to leave it loose on the tank block instead.... Fire then an email and ask them....

I machined me a shim to fit between the reg and gun to time the gauge on my .25 air rifle.

Contacted Ninja concerning the bottle/regulator and bonnet adjustment. This is their reply:

Thank you for choosing the gauntlet and we prefer the second option and the way
you received it. we do not recommend you loosen and rotate the bonnet but turn
the entire reg in the receiver to align it as there is plenty of sealing surface
and thread integrity with the regulator and receiver.
If you have any other questions or concerns let me know.
 
I want to thank everyone for your replies and input. And Bob, thanks for your suggestion to check with NINJA first and get their recommendations. May have saved me some headaches and my a**.  :) :)
