Help with major rust problem on my MK12.
I opened my Pelican case to a very rusted MK12 Mod 0 tonight while getting something off of it. The barrel, which has a rustolum coating on top of the Douglas black coat had rust on it that I can clearly see through the holes of the PRI handguard. The chamber has rust in it, and the inside of the barrel was coated. In my hast to get the uppper stripped to start treating the rust, I have two allen screws that cannot unscrew. i did not locktight these either. They consist of the one allen on the added straight top forearm rail, and the allen screw that holds the Ops Inc suppressor collar in place.
I'm not worried so much on getting these last two screws off as this will be going to the smith tomorrow afternoon to handle (home built). I am very frustrated and curious as to how I got so much rust on this weapon in the three weeks since I cased it after a quick barrel swab and some CLP put on it.
My last outing with it was with my neighbor shooting at some pest deer destroying a friend's garden here in TN. We did this shortly after a rain soaking but the rifle was not uncased prior to that.
I have everything I thought has been right: keep it cased in a quality case, keep it lubed, and generally cleaned. I am mad beyond reason right now. What did I do wrong? Can my barrel be saved?
