definitely reg creep in my .22 avenger

[gendoc]

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

It may also settle in after a number of shots. How many rounds have you put through it? The reg may just need some time and shots.

 

[gendoc]

about 600-800 or more, i was in the 1st batch that was delivered in late july....i think it was ??

i have tuned it about 10 different ways up and down. i like the performance overall with the 18gr.

Try starting with a lower fill pressura and fill more often.

155bar seems rather high IMHO for 18.1gr JSBs. I would try and lower it starting from 120-125bar and go from there.

 

[gendoc]

ive started with 2.8K all the way to 4k.

i really dont believe it can be remedied. i just have to live with it til the warranty is over unless it gets worse.

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.

Mine in 22 does the same thing with reg at 2200. Takes 3 or 4 shots after sitting to get back right. I just dry fire before loading the first mag in. Overall can't complain too much for the price.

same here...thanks !!

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

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.

all is good, my eyesight limits things i can do.

thank goodness for good optics !!

 

[nervoustrig]

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’

 

[gendoc]

I use a lighted magnifying glass to read the gauge. It only requires 1 hand

 

[Keyman62421]

Does the gun come with a tear down schematoc?

 

[glr59]

Just wondering what pressure you guys that are seeing reg creep are storing the gun at? Does reg creep occur if you store the gun at say 3000psi instead of 4000psi + ?

[Odoyle]

Sometimes regulators (in general) acts a little stupid when filled past 2900-3000psi during storage.

 

[MrPink]

Same problem with my avenger. It creeps no matter the fill pressure. I've let it sit after a shooting session and refilled after to the same result. She creeps a little regardless the fill pressure 

 

[Jimmy001]

its simply put a seal in it.i have that gun and i have fx's and edguns. And the first thing i do when i get a gun is pull it apart polish all reg parts and lap the barrels.And i can tell you that reg is built just as well as my impact. that just shows how overcharged we are on are high end guns. the stores make 700. on an impact when they sell it.

 

[nervoustrig]

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.

Thanks Jimmy001 for your view on the regulator.
