So I bought a new Remington 870 Express as a Christmas gift to my fiancé it has been stored in my gun safe alongside of two other Remington 870 expresses and also a Remington 870 Wingmaster. The new 870 hasn't been fired or handled in adverse conditions, pretty much taken out of the box and put into the safe, and the gun safe has several fresh desiccant packets in it. I went to get the 870 out today and package it up and put under the Christmas tree, (been hiding it in plain sight essentially till we got the tree). Well there is a ton of rust on the barrel and action. The rust cleaned up easily and seemed to be just superficial but was wondering if anyone else has had problems with it lately. The finish on the new 870 seems to be different than what is on my two older expresses, one of which is an early 1980's and the second an early 1990's. Anyone have a similar experience?
