How tight should the shroud of a marauder be over the o-ring of the air stripper? Mine doesn't fit tight at all, and I believe that it was a lot tighter when the rifle was new. I am having accuracy issues and am trying to troubleshoot.
A tight fitting o ring on the stripper and a barrel band from Tim Hill at hillairgun.com are two of the best things you can do on a marauder to battle POI changes.
