Jay a supermoderator at the website Canadian Gun Nutz posted some pictures he took at the 2016 Shot Show in Vegas from the Leupold booth. Leupold was featuring a number of rifles with their scopes that had been lost in the wilderness for extended periods of time and when found were still functional. Fun stories if you take the time to go to the post here. You should not need an account to view the post.
For those of you who don’t know about Canadian Gun Nutz it is a great site full of articles and posts and is very active. They also have a very busy equipment exchange section however you will need to register and request access in order to browse the guns. Beware that doing so might require you to increase the capacity of your gun cabinets.
