Fx drs oring failures anyone?

Received my fx drs classic .22 700mm with the shp plenum .
Let’s first say that when this gun is sealed it’s a tack driver not only at 100 but even out to 200 yards !
Unfortunetly 6 out of 10 outings an oring failure has occurred 3 of which has been an oring on the barrel that holds the compressed air in res. To back flow through the transfer port .
Next failures have been one oring between the shp plenum and receiver .

Next failure has been the oring to seal probe inside of transfer port body .

And yet again a oring failure on the amp regulator body .

All these failures appear to be the oring delaminating leaving bits and pieces behind during removal .

So I ask has anyone else ever found a bad batch of orings on a rifle or manufacturer ? If so can anyone point me in the direction of some higher quality orings in the states ?

I recently bought 2 synthetic classics in .22 cal when they came available for deals pre-owned. As received they seem to prefer 15.89's, but that's O.K. with me as I will likely shoot Hades/Atomics through them. The 500mm gun is just awesome - light, handy, accurate, just a tiny bit low velocity on first shot but overall small ES. The 600mm gun wasn't so good with a 30+ fps spread over 12 rounds (Orion mag capacity, and these mags are great!). And that was the ES after burning 2 dry-fire shots. It has gone back for service. Might not be the gun's fault as I don't know what the original owner did to it.

Would love to see a few more shots available per fill, but I knew that limitation going in. I also got the dreaded block with the M8 threaded pressure gauge (at least on my 500. Don't have the 600 in hand to check). Got a couple of the new M8 threaded Sekhmet gauges ordered just to see first hand how badly they protrude out from the gun's OEM slim profile. Will be nice to have confidence in my gauge accuracy if I end up using them. And the Sekhmet folks have been really nice to deal with - at a time when customer service sometimes seems to be a lost art.

Fortunately no o-ring failures on my guns yet.

I recently bought a DRS .22 600 had It about a week , the valve seal let loose dumping all the air out of the barrel enough to give a guy a heart attack , anyways I sent It back to the supplier for repair ...Its still there . Its not the first problem Iv had with FX I think Im done with FX air guns .
I can’t say I’m done with fx .. but rather aware that I may need to change these rings out to better ones before tuning and sighting in

Mine is the heavy slug liner so anything over 25 grain shoots amazing .. I’ve seen some super consistent shot strings and with the shp plenum and at 150 bar for slinging them 30+ grain slugs over 900 I’m seeing about 16-18 shots before a fill which is fine as this gun is strictly a target rifle and stays teathered
 
Well a good days work and a few cuss words and the drs is back to holding air and shooting .. I found several other orings that you could delaminate using fingernail .. I’m guessing I just had a bad batch of rings on this gun . Went on to the tube 100yard range and shot a .565” 5 shot group using griffin boat tail slugs .. she’s back but when will I need to go down this road again .. hopefully next year at the soonest
