I'm new to anything that starts with "marlin" so you'll have to forgive me if this seems like an incredibly stupid question. Referencing the photo below, do I have something to worry about?
The rest of the bore doesn't look bad and my new baby does need a cleaning, but shame on me for not noticing this before. Of course, it could be normal given the patterning. It's literally a ring inside that narrow zone of the barrel interior, which strikes me as an incredibly isolated area for rust. If it helps, the serial is 98series (2008?).
On a side note, it looks incredibly sexy with my katana.
