The Burris Eliminator is one of their newer scopes, and I thought of getting one myself except I learned that it won't operate under something like 17 degrees - here is Montana, much of the hunting season can be a whole lot colder than that. so I probably won't get one. Burris does have a marvelous guarantee - for the life of the product regardless of whether it belongs to the original owner. I would take advantage of that it I were you as that is not a cheap scope by any means, but I would first check out the bases and rings to be sure that they were tight. By the way, having the scope installed by a gun shop is no guarantee that it will be done correctly; I have seen some terrible mounting jobs done by "professionals", including a scope whose rings were OVER TIGHTENED to the point where the tube had been crushed. If I were you, I'd get someone with a good and verifiable reputation to check all this out for you. Good luck!
