I actually bought the zeiss z- point for my ross 337 because of the high praise that "moonkkret" gave for this red dot. After I received the z-point with archery bracket i realized itwould take a lot of time to set it up properly on a vertical bow. IMO it sounds like it would work well on a crossbow which is why i want to use it. it cost me app 300.00 with archery bracket for vertical bow. I kept it since i felt I would eventually own an x-bow so it seemed like a good choice. it also weighs about 4 oz which i thought would be helpful when you consider the weight of a crossbow. I will look into danny miller for the extra's. The phoenix will be here this week but I will take my time in deciding what i really need to make this package complete.thanks for the input. Any other input is appreciated.
