Today, I was able to take my AR out to the range to sight in my newest purchase. A Sightmark Ultra Shot QD Reflex sight with Digital Switch, and 5x Magnifier. If you are looking into one of these, BUY IT. Mixed reviews made me hesitate, but mine was great. Certain people have had issues with it turning off after every shot, and believe that it can't handle the recoil of 5.56. Simply not true. I did have an issue with mine turning off after every shot, but I TIGHTENED THE BATTERY COVER. No more issues. Easy to sight in and maintained all day. The glass on the 5x magnifier is extremely clear, and the flip to side mount, while a little loose performed as expected. Overall, very pleased with my purchase, if not my marksmanship.
