Looks like the sleeve has some dimples/riples in the bore,would be interesting to see what a micrometer showed.@Street Ryderz I would like to see what he thinks about that wear pattern. Looks like there is some scoring to me.
Ordered 47x2 Caber rings off of egay. No info other than size but they are cheap enough. Hopefully they have a part number. Also found some poloni (sp?) rings but again, no info. Still searching. Now I'm using Google for other countries.
