I have a Zeiss Conquest 4.5-14x44 with the Rapid-Z 800. It has approximately 60 firings underneath it. The glass is perfect; not a mark on it. It has been mounted in some Burris Signature Zee Rings. There are some ring marks on it, but they are barely discernible. This is one of my favorite scopes and would make a great scope on a lightweight packable rifle. I am selling it because I want to try a Viper PST scope. The only issue with this scope is that I took it to the range one time and I forgot to put the elevation cap back on. I am selling for $550.
