Another point concerning the rust on the finish is that it might have not been wiped down in awhile and or stored in humid conditions. I don't know of many guns that would not rust eventually under those conditions. I have stories from numerous duckhunters how well these guns hold up in their type of hunting so I wouldn't worry about the rusting. Most guns with a matte finish and are blued are prone to rusting. Simple fix clean off all the packing oil and gunk and wipe it down with Eezox.
