It seems some people don't like them, and I'm not sure why. My buddie and I each have one, 3rd gen. Gov. Model, 6x20x56mm, with mil dots and lit reticle. We both love them. We have both had them out in cold, wet, hot weather, and have never had any problem with them. I really like the internal level bubble. The optics are just as sharp and clear as any Leopold I've ever seen. Even on 20x there is no noticable light loss. I think they are great and highly recomend them.
JMHO and .02 FWIW
