| If you are having a real hard time finding light viscosity oil try looking at hobby stores for RC shock oil. I want to say it was light weight hydraulic oil. But I am not certain at all.
You could ask for scotty in the tech service for tippmanns ft wayne IN ofice. Just ask him what oil he reccomends fo the FA shock sears, Scotty was the one who rebuilt my FA's for me last time. |
