Karma Karma red panda second regulator issue.

[rickschowengerdt]

Good afternoon, went shooting today and notice that I have a regulator issue. When I start a slug testing session. I noticed that the second regulator will start falling off pressure when it's not tethered to a bottle. When the gun is tethered.
The regulator seems to work normal. When I get home and set the gun on my table. I notice that the regulator will creep past the original setting. Gun is in 22 caliber, SHOOTING THE NEW AIR MARKSMAN, 40 GRAIN PRECISION slug first regulator is wide open.
The second regulator setting 2600 PSI.
Any help would be greatly appreciated.
Sincerely, Rick.

Sounds like reg 2 could be compromised. There are some fluctuations with heat but creeping up usually means a hurt oring or reg piston seal/seating face.

need to replace oring on adjustment screw. It would be the bottom if there's two. On my amp regs anytime I see they've creept,I replace the bottom oring on the adjustment screw. Fixes the issue everytime. Sometimes it lasted a year and sometimes less,depending on sitting changing temperatures. The more a gun is subject to temperature change,the more those orings are stressed. I've not had my pandas reg apart,but I'm sure there's an ori g on the adjustment screw if not two. If the pressures rise past the set point,it's usually the bottom oring.

Could the o-rings cause the regulator to fall off? When I am on just the air guns bottle. And not tethered as well.

Yes,

Get yourself a digital gauge for your #2 regulator. Preferably one with a right angle adapter and mount it on the left side if you are shooting right handed. You will know for sure if there is any creep and when it happens. You will also notice how long it takes between shots to acheive a consitant psi reading between shots. You may or many not be suprised at what you find.
