I have a Savage with one on it. It is a 4-12x50mm. It is clear and hasn't shifted point of aim (on a 7mm Rem. Mag.). I did however have a problem with mine. About 3-4 years after I bought it, the power adjustment ring locked up on me and they could do nothing with it at the shop I bought it at. But since it has a lifetime, over-the-counter warranty, they replaced it right in front of me with no questions asked. And for the couple of months I have had it, it has been wonderful.....but, after the first trip hunting with it, the cushioned eye ring poped off so I have a very sharp exposed edge if I ever misalign my eye/cheek on the stock. Well, this is all that I have to say about the scope I have. Hopefully someone else will respond with something good to say. All and all, I think that they are really good scopes and are better than some of the other scopes on the market. Hope it helps
