ML 10 part

[mcm24]

First post! I disassembled my ML 10 a week ago, came back to the bench last night and noticed a rubber o-ring about 1/4" lying under the bolt.. No chance that came out somewhere is there? Never noticed one before. Can't find one on the exploded view. I don't want to reassemble until I'm positive. Thanks in advance.

I don't think a rubber O-ring came from the Savage 10ML.
