    All righty then !
    I did my research ,I read the owners manual, I searched YouTube........ but I can not find out how ( or if its even necessary ) to remove that ring on the gas piston .

    Jerry Miculek go's into great detail on how to remove/clean the piston/rings on the Mossberg 930's .......... so whats up with little if any info on the poor SA-20 ?

    Sorry, very busy time of year. last few matches and Christmas.
    I have never taken the piston ring off. I would not try it as it is a thick ring and will likely break or deform.
    I clean it with the Remington shotgun spray cleaner and let it soak. I shoot the cleaner in the ring gap and turn the gap around the piston.
    When really cruddy I will use shooters choice barrel cleaner and let it soak
    I saw the JM 930 cleaning and it looks like that has multiple thin rings.
    I'll check with Mossberg and report back.

    Brian ,
    no need to apologize - good things happen to those that wait ...........
    If a good soaking is all it needs -thats good enough for me !

    Since to render flawless functioning - my 930's need to have their pistons meticulously cleaned regularly , I thought the same would go for my SA-20's
