I've had my Ruger M77 Mk II all-weather stainless (skeleton stock) for 18 years now. In those 18 years it's seen rain and snow and in all those years I NEVER pulled the action from the stock fearing I'd change the point of impact or something stupid like that. In any case I pulled the action tonight expecting tons of rust and gunk.

It looked like it just came off the assembly line. I was shocked. How could this be? I wiped it down with a slightly oily rag and then a dry towel and put it back together.

Good for another 18 years!!!
