I received the parts to get my gun shooting again . Thanks Julian

Thanks , i wasnt sure if someone was experimenting. Do you know the part no. for this is ?

When i stripped down my 410 i found a plastic or nylon type washer in place of the oring between the breech block and the firing valve body . Did they use this in some models or did previous owner use this ? Thanks in advance .

I read when refilling an empty gun you need to cock it so the pressure is off the firing valve . If that doesnt work you may have to replace the orings .
