I havent used me new Walther in the rain as yet, but I know there will be a time soon where I will. Im wondering though, what maintenance is needed on this rifle (walther dom alutec LG300) should it get really wet from rain? Do I have to remove the action from the stock and wipe it down with a oiled cloth? Or can an external wipedown with a oiled cloth be suffcient? Your thoughts?
