I just purchased a new Umarex Gauntlet last week. I have roughly 200 shots through it. Earlier today I was shooting some long distance shots and I shot below 1000psi. After I brought it back inside I tried pumping it and it would not hold air. The air is leaking out of the end of the barrel. I took the tank shroud off and pumped the tank back up to around 2000psi. After I screwed it back in all the air leaked through the end of the barrel again. Is this an easy fix? I am new to pcp's and do not know much about them.

It should be an easy fix.

Try taking a couple dry fires. Preferably, pump the bottle back up and snap off a couple quick shots before the air leaks out. Its the poppet not sealing. May just have some crud in there.

If the valve is not seating, look at the JSAR video on how they seat the poppet using sandpaper. It works better than just spinning it.

I have 2 of these & totally agree with RJ-I would try pumping up to 2000 again, but cock gun, then screw in tank & quickly dry fire several times to seat poppit- the video suggested is only for the JSAR poppit which needs to be burnished & is much harder material. The stock poppit is a very soft material & will be destroyed by doing this. If gun still leaking after above, then you probably have some particle creating leak at poppit seal. In this case, 2 options- send it back or tear apart & clean poppit & seat(but if going that far ,would get tune kit & replace poppit.)
Hope this helps

Tried dry firing. I tore it down last night and cleaned everything and it's still leaking so I'm just going to send it back.

I was sooting in an extreme field target competition and in the heat of 100 degrees the gun fired at a target and a loud leaking sound happened everyone there said blown o ring but when I fot
Home I pulled 99% of the whole gun and found no bad o ringed tryed filling just the air tank and it held but as soon as I screwed the bottle back in air rushed out the barrel and the bolt breach I am lost and after haveing an issue with an other Umarex product that needed replaced I want to resolve this myself any help would be greatly appreciated

Air rushing out of the barrel means the poppet has failed or a piece of debris is preventing it from seating.
The third possibility is that it is simply being held open by the hammer spring. So before taking it apart to inspect the valve assembly, try cocking the gun first and then attach the bottle to see if it will hold pressure. This is a common issue new PCP owners will encounter, though it’s a long shot in this case because the initial sequence of events you described is more indicative that the poppet isn’t sealing.

Ok the bottle is seated and the gun cocked and it’s holding air not unlike before where every thing I put in it just rushed out it’s holding at 1000 psi so what’s that mean I will have to cock it like this every time to get it to hold air or something else thank you so much for your help

That step is only necessary when pressurizing from zero. Now the pressure will keep the poppet seated.
My advice would be to go ahead and bring the fill pressure up to something comfortably higher than the regulator setpoint. Like 2000psi at least, and go ahead and fire off a few test shots to make sure it doesn’t promptly start leaking again when fired.
The question as to why it evacuated the pressure last time could be early signs of the poppet failing, or maybe you had just accidentally continued shooting it after the pressure had dropped well below the regulator setpoint.

That’s true when it started leaking it wasn’t very high pressure it was air but not a lot of air I could have low I hope it’s not that other part do you know if I can buy a build up kit for this thing like a upgrade rebuild

In my experience with the Gauntlet 2, THE HAMMER MUST BE COCKED when filling from zero. If you remove the bottle the valve hasn't any pressure behind it, so it's basically at zero. In that gun the hammer rests on the valve. Once you pull that bottle
off the hammer arbitrarily pushes the valve open. When you screw the bottle back on, the valve is still open.
Cock the gun then put the bottle back on. This is common with these guns. If you still have an issue then it really IS the poppet seat or spring, or dirt stuck in it.
Good luck!
