My Sako AV I just bought came with gloss blued optilok rings. I'm wondering if anyone has ideas for a rust protectant that is not lubricating. I want to degrease my screws and mating surfaces of my scope mounting system, but I don't want the blued steel to rust. I've only dealt with shotguns and stainless rifles before... Not blued rifles. So I am very worried about rust when not coated in grease or oil. Thoughts?
