My local store has a used 590 Mariner for $350. I like the 500/590 series, but I don't know anything about the Mariner and the Mossberg website is not particularity helpful.
Is the "Marinecoat" finish applied to the internal parts? Are there any other advantages or drawbacks associated with the Mariner, apart from corrosion resistance?
For context, this gun would fill the role of a spare to my existing 500, and possibly as a beater / truck gun.
Thanks.
