HW100 Oring OR129, where is it?

[NorCalAirgun]

Hi,

Hope some body may help me on my HW100. According to the diagram, there is a Oring (OR129) inside but when I open it and see no Oring. As the picture shows there are two Circles (black area), inner and the outer. Is the inner circle is the Oring was compressed down? My gun has air leaking and I am trying to replace the Oring but sure where the Oring 129 is.

Thank you,

Ty

Norcal,

go to the Weihrauch owners club website. there was a difference between the UK rifles & the high power ones shipped to us in the USA. i found the correct info there. i'll keep looking, as i went thru the same thing with my two HW100's.

Thank you Scott for the information. Look like the oring AR129 on my gun has been compressed down so long so it flats to the adjacent metal surface. The oring was deformed and not able to go back to the original form.

Has it fixed your leak?

Not yet because do not know how to and afraid to damage the gun. If I buy other gun, I refer the easy one such as Edgun.
