Firearm maintenance rule #1 - oil it. Oil isn't just for lubing moving parts.
When I worked behind a gun counter a couple years ago, a guy bought a new Rem 700 from us. Brought it back 6 months later because he was unsatisfied with it because of rust and demanded a new one (right before deer season).
I looked at it...just surface rust. Nothing serious. He stated he took it out 2 months prior (during the summer), shot it to sight it in, and put it back in a soft case. I told him we can't return or exchange firearms, but we'd have to send it the the manufacturer if he wanted it fixed.
I got an AP brush, some Break Free, and cleaned it up in 2 minutes. He thanked me and took the rifle and left. Or at least I thought he left.
He immediately went to the manager and told them I had no idea what I was doing, that I am wrong, and that his gun is in fact "defective"
So I packed it up, and sent it to Remington so they could look at his discrepancies and fix any problem from the manufacturer.
But of course, the gun was boxed up and shipped with heavy amounts of oil (don't want it rusting on the way there
).
We finally received the gun back 4 months later with a letter from Remington that pretty much stated "
".
He got mad because he missed out on deer season without a gun
