picked it up this afternoon after putting it away last evening.

my reg is set for the 18gr jsb @ 950fps which is about 2250psi

it showed 2850+psi, so i guess i'm used to high-end guns that are stable.

i will wait til the warranty runs out next year before i reg it out, unless it gets out of hand...

then it goes back to AGD !!

i really like this gun and it shows alot of promise, i guess i can just shoot it in the ground before going 

to the woods hunting to reset the reg 🤘
 
Mine does something similar but not so extreme. Usually creeps up about 200psi then stays. I have it set at 1700 reg and just just checked it about 24hrs after my 4100psi fill last night, yep at 1900. It seems to take hours to get there though I do notice a 10-20fps jump when chrono testing between lazy mag changes or if I get up to do something and come back to it. Small spike every 10.

FWIW

Did you try contacting Air Venturi? A few guys on GTA had this same issue and most said the creep was caused by the delrin seal in the regulator. One poster said he was sent a replacement from Air Venturi for a little of nothing, after going back and forth with them.

What he said.

Smooth the seat of machining marks or replace it.

I’ve fixed many a creeper by simply dressing the sealing surfaces smooth and flat.

Fair enough! Tyler at PA confirmed there is an opening behind the plastic disc so it would be a trivial matter to push it out...in which case it becomes a simple and foolproof task to flatten it by wet sanding against a piece of glass or a granite. Granted, if your vision makes it difficult to perform the disassembly / reassembly, that still may not be in the cards. However you can apparently read the puny gauge and I suspect that’s sufficient visual acuity. Just sayin’

FYI a guy on GTA just reported back that he flattened and polished the seal on the end of the piston and the creeping dropped from 800psi to 200psi, and presumably it will get even better after it has been cycled a number of times to help the surfaces iron in together. Must have been a pretty bad defect but just goes to show it can be addressed.
