Chunks missing out of the oring mean a burr as keyman stated. More than likely it is.so small you cant see it. If you cant feel it (or your finger cant get in there) try using a q.tip. just lightly swirl it around and see if it catches on anything. I believe the housing is brass so if there is a burr it should be a pretty easy clean up.
