I have an old Bushnell(about 30 years0 The other day I dropped the rifle on a cement sidewalk and dinged it pretty good. I did the freezer thing with it. I put it in the deep freeze overnight then threw it in a sink of hot dish water. No fog or steam or anything. Quess its ok. Still shoots good. I love the newer Simmons 6X pro-hunter. I took it out a couple nights ago along with my best Luepold. I watched some deer with them in the park acroos the road from my house. That Simmons showed those deer much clearer about dark than my Luepold. Time will tell weather it will stand up for many years but I am betting it will. There are bucket fulls of scopes under 250 that will last a life time or two and give excellent service. I have never missed an animal or a shot at an anuimal because of a faulty scope. This in 48 years of hunting with scopes.
