I have never had one on a rifle, I do have a Bushnell Elite 3200 on my Remington XP100R 260 Rem., I have not had any problems what so ever out of it. I am quite impressed with it actually, I replaced a Burris scope that I had on it with this one and can honestly say I like it better than the Burris. I have a 4200 Elite on my Bushmaster, I like it so much that it is what made me try this scope.
