I have a Weaver Rimfire scope on my CZ in .22 as well. Also, as a moderator, I had never owned a weaver, so I wanted to buy it and have some first hand knowledge and experience with it. I must say, I am impressed with the quality and performance of this little scope. However, a friend of mine has the Leupold version on his .22 and I think that, for a relatively nominal price difference, the Leupold model is worth the extra money. It's not that the Weaver Rimfire is a bad scope - I'm definitely not saying that - I'm just saying that the Leupold version is a better scope. As most people know about the saying that I also reiterate, "you get what you pay for," this certainly applies to optics, but, again, I think that the additional money for the leupold is worth it.
