warm moist air is less likely to condense on the cold metal if the metal is protected from the moist air and can come up to temp ... I use a case and wrap a blanket around it -- if it is coming inside - and you can fall asleep if you like as long as you didnt soak the case with a dunking or rain. One of the nice features of the ZKK action is that you could also quickly dismantle the bolt AND it has no little ejector plugs held captive in blind holes or extractors with tiny springs buried in blind holes .. both of which can hold condensation and rust or freeze ... the true mauser design (and "some" pseudo mauser designs) is easier to maintain AND (forgetting the so called "controlled" feed) it has POSITIVE extraction and POSITIVE ejection ... even when covered in snow or ice
True, my 600 and 602 are easy to degrease when the weather gets cold.
