i got the dback tac and tbh, i regret not shelling out more for a viper or going athlon ares/midas. supposedly the glass is better on the vortex, but the complete lack of ZS or revolution indices will probably really annoy me and at the distances required for rimfire, slightly lower quality glass doesnt really matter at <200yds. i havent even used or mounted it yet cuz my rifle isnt in, and im already thinking of buying another scope
