The Zerotech Vengeance is practically the same as the old Bushnell AR series of scopes—they came from the same Chinese factory.
I have the Zerotech Vengeance 3-12x40, the Athlon Talos 3-12x40 (again out of the same Chinese factory, so very similar, just lightened down) and both Bushnell ARs in 3-12x40 and 4.5-18x40.
After mounting the Zerotech Vengeance on a .25-06, I found the glass to not have the clarity required, and the weight was too much (although the Athlon Talos was lighter, it too failed on glass quality).
Therefore, I personally only use these four similar scopes on my rimfires - they won't be going back on any of my centerfires.
I must mention a big plus for Zerotech, and that is their warranty as it is great (as good as the Leupold warranty... and that's saying something).
