I have dropped my rifle down a 50 ft rock cliff to save my life. The rifle took direct hits to the bolt handle, Zeiss Conquest scope, Talley Lightweight mounts, muzzle, and stock when I went on a tndeer hog hunt. Took the rifle to the range to see if it was still on. Sure enough, it was dead on. I haven't touched the adjustments on my scope. After seeing what the mounts went through, I'm sold on them. I haven't read many bad reviews about them at all. I would be interested to see why they didn't give them good reviews.
