From a quick observation not mounted on my gun yet, the crosshair post are alittle heavier than the Z5. If I have any complaint against the Z5 this would be it. It will get you well beyond shooting hours but after selling my Z3 4-12 I wish the reticle was alittle heavier. The other thing I noticed was the Z5 seemed to have a wider field of view(meaning the picture went all the way to the edges). Hope to get it mounted up within the next few days and try it out on paper.
