Cometa lynx Problem

[eng.amg]

Hello everyone,
my lynx 0.22 had a problem in the check valve that allows the air to come out after refill.
i did replace the O ring of the check valve and that problem solved.
But after that i found that there's air leak in the barrel when i take a shut, right behind the barrel.
I did check the barrel is installed in the right place and the screws is ok.
any help!!

Sounds like your valve isn't seating correctly, did you remove the main valve poppet when you took the gun apart?  If not you may need to and replace the seal material.  You should be able to get the parts shipped to you directly from the manufacturer or a local distributor in your country....

Now i took the gun apart and tack out all O rings in the barrel and that small yellow part behind the barrel, I bought a new O rings and will replace them all today.
But i don't know if you mean that valve in the tube between the barrel and the air cylinder?
if yes i didn't remove it.

I did replace the O rimgs in the barrel and the metal yellow part behind the barrel, "I don't know what it's name"
now i found when i take a shot, that the air comes out from that part in the red circle in the picture.
what cause that ?

Sounds like you either lost or didn't install the breach seal or transfer port seal correctly...

Can you send a picture for that port. i can't tell where's it

[OleTomCat]

Here's an exploded view of all of the parts, I believe #50 is the breach seal, the descriptions are in a language I don't know.

Thank you very much for this picture i really need it. but the barrel O ring #50 is installed i'm sure about that. i was going to replace it but i didn't find it in the store. is there's any o rings else may cause this problem.?

[OleTomCat]

There should be a seal where the air travels from the valve to the barrel, that's called the transfer port, I can't tell from the diagram where it is.

From the diagram i see there're three O rings can cause this leak. #80, #50, and #4
#80 has been replaced, as i don't see any damaged in #50 and #4 I didn't replace them. but seems i'll just for sure.
I'll search for them in another store tomorrow. Hope it'll solve the problem.
