Umarex winchester rifle

[Zachariah]

Hi
My above co2 rifle suddenly lost all co2 from capsule. I tried another one and no good I suspect one of the seal has gone.
Can they be repaired? My local Gun shop can't help as its out of warranty. I don't think it's seal where the cartridge fits.
Any advice would be great.

This is the problem with these rifles.
They are unique and have a Lothar Walther barrel for accuracy
But they also have tiny o rings/seals which blow and are really difficult to fix.

Ive just had the same problem with my 88gram silver one ,gas blowing out of breech.
My friend Baz is going to try and fix it.

First thing that you do need is the Walther co2 12gram adapter- otherwise you are going to blow a lot of 88 gas when testing.
Then a seal kit which I think Chambers do.
Then a repairer with a lot of skill and patience!

Having looked at Chambers parts I am a bit more hopeful.
They have internal tubes with o rings fitted,new valves etc.
