i bought two rather expensive red dot sights: One is still in its original packing. Mounted the other one on my CVA StagHorn. On the range in good light it did well.

The sight was really sorry in low light. While watching a pond from a stand a doe came in about 30 years in front of me. The sun had just set. Deer season was not in but i drew on her for practice. i could not have shot that deer. On the lowest setting the dot was much too bright and the resolution was awful.
