This is a little hard to describe, but I have noticed a white film forms every week or so on the rearmost, upper corner of the piece of metal that is welded onto the front of the Maverick barrel (the piece that the takedown screw goes through). I wipe it off, and a number of days later the same white film is on the exact same place on the metal piece. I'm wondering if something might be leaching out of the weld? Is this possible? Has anyone noticed anything similar on their Mossberg? Any insight would be appreciated. It doesn't seem like a big problem. I wipe it off, and it goes away for a while. I just find it odd that it keeps coming back on the same spot, and is not seen anywhere else of the gun.
