Daystate Daystate revere .177

[.177Guy]

Hello guys,
I just bought a new revere .177 from aoa,
And after first tank I realized the sound of the rifle changed,
Upon inspection a portion of o-ring that holds the transfer port in place was sticking out just under the barrel breach port!!!
Called Aoa and they said it happens after every 600 or shots!!!
They are sending me some spare o-rings and if that won’t work,
I can send the rifle back to Aoa,
Now my question to all u guys who use these pcp’s
Since this is my first ever pcp,
Why manufacturer has this portion shaved off at the entrance bottom part of the barrel port which is letting the o-ring slip out under pressure???

“Called Aoa and they said it happens after every 600 or shots!!!”

Somebody was just bs’ng to get you off the line. Swap the oring when it gets there and you should be good to go for a long time.

Thanks for quick reply sir,
But can u tell why that part of barrel is shaved off which is letting the o ring slip out??

The flat breech bottom should have nothing to do with it. The TP O rings are captured by the TP itself. Unless it's torn apart, I don't know how it could reach that location.

Thankyou for ur reply sir,
Here is a picture of o-ring after I reseated it!my question is why leave that room for error???
What is the purpose of that shaved area ??

 

[.177Guy]

And just for u guys wondering,
I did try to replace the barrel end o-ring with the tank end o-ring since it’s the same size o-ring,
But the result was same after few dry fire shots the rings slipped right out of that breach area???
After 4 consecutive times of trying to reseat the o-ring in vain
I have come to the conclusion
That barrel is defected or u can call the barrel is shaved off more than it needed to be???

Guys what will happen if close this breach gap let’s say half of it or quarter of it with something!!!
Like steal putty or some thing???

I would send it back rather than attempt something that may void your guarantee.
The gun should not be doing that even when dry firing. There is something not right there.

Yeah man,
Aoa sent me return label right away,
And aoa also sending me a set of spare o rings for transfer port,
And aoa said if new replacement prongs don’t hold just use the return label and send it back and aoa will take care of it!!!

 

[.177Guy]

But fellas my question still waiting for answer,
What will happen if I close let’s say half of some portion of this breach area??
And also what could possibly be causing the air to back fire and make the o ring pushed out,
It’s brand new rifle
and worked super sweet for the first tank and then went south afterwards!!!

I'm trying to understand how this happens. When you "reseat" the O ring, then obviously you disassemble the action, and with the top and bottom modules separated, you place an O ring into the transfer port recess. Then, when reassembled, the O ring encircles the top of the brass transfer port, which fits into the barrel breech. At that point, I don't see how the O ring can end up in the position shown, since it is captured between the transfer port and the breech cutout. Very interesting.

I've had my Revere for over 7 months with over 5000 shots and that has not happened. I don't see how that o ring can migrate there without it being broken or not installed properly.

I just looked at mine,looks ,my o-ring is on the probe,,the gap has nothing to do with the oring,.maybe if you check a parts list you will have a better idea of what you are going to talk about.

That's the breech seal on the probe. His issue is with the transfer port seal.

LOL,I am the one who better looks at the parts list,Thank you I just found this post on the Huntsman teardown.
From Peskadot671 from July,12,2018..it is informative ,here on this site

Ok guys my first ever pcp after years of contemplating which one to get has been shipped back to the dealer for inspection after having it for no more than one tank of joy !!!
Bad luck I guess!!!

 

[Spartan]

That shaved off portion you asked about is there to catch blown out o-rings.

No, I'm just kidding. I don't know why it's there but it's there for a reason so no need to fill it with anything. AoA will get you squared away. Those are great guns, you just had an fortunate hiccup early on. Fear not.

FWIW, I do remember another user a few months or so ago that posted about the exact same problem. You could probably search for that thread to see if any insights are there.

Ok guys a little update on my revere .177,
just got it back after 2 weeks from Aoa,
apparently the repair guy at Aoa said that the brass bushing that sits on the tp was undersized from factory and they just replaced it with bigger size and tested about 50 shots using 16grain pellets to stress test the rifle,the rifle held its seals with no problem.
i just shot like 4 13 shot mags through it using 10.3 grain and it is functioning fine…
quick note;
this revere does shoot slugs much better than my fx drs.

 

[Joedirt199]

Glad it sorted out. Revere is a shooting delight. What slugs were you getting good groups from. I hear the JSB slugs work well.

The zan 10.03
and jsb knockout 10.3
both were spot on.
one thing I don’t understand is the
fps were around 810-820ish…
even though these slugs are lighter in weight compare to jsb heavy 10.34 which gets me about 850 fps!!!
Very strange…
