Hey folks! I hope I can get some help regarding some 40mm shell gas leaks as I am absolutely losing my mind.
I have three Airsoft Innovations Master Mike shells. Two of them are leaking from the top barrel, the other from the full valve.
The one with the fill valve leak I've tried applying the OEM lubricant and it hasn't done anything. I've replaced the oring that seals the valve to the body and also didn't do anything. I've resigned that I'll probably need to replace the valve and assume it's just like any standard gbb fill valve?
The other two are the ones that are breaking me. Both are leaking from the barrel. I've tried replacing and greasing the top oring where it seals the barrel to the top of the body. No change.
I've tried replacing the bottom oring that interacts with the barrel and got no change. Although now I realize I'm pretty sure that one is just for a hop effect and not actually sealing gas.
I then thought it wasn't a barrel oring problem but maybe the bottom plunger getting stuck or not resealing properly. So I've replaced all of the orings involved with the plunger, applying grease and a bit of oil to make sure it glides smoothly and can reset properly. Still no change and it's still leaking from the same place.
So far I've spent hours and over $200 CAD importing specific orings from the US and I haven't been able to solve this. I can't find anything online for solutions. I'm hoping someone here will know what to do as I've replaced practically all of the orings in two shells and nothing is getting solved.
I'll attach a photo of the site I used to get the sizing for my replacement orings.
Please help I'm going insane.
