Great value dual color red dot - UTG Pro 4.2in ITA CQB Reflex Micro Red Dot Sight w/ Integral QD Mount

I purchased this red dot to use in conjunction with a Leapers UTG 3X Magnifier (also purchased from OpticsPlanet) to put on my Excel Arms AR57 (5.7x28mm). My first use was at an outdoor rifle range, and I had no difficulty with the brightness of the reticle even in full sun. It's really nice to have red and green in the same unit. It was a cinch to zero, but I've not yet had a chance to put a lot of rounds through this gun to determine how well it holds. However, I'm not worried about it due to the low recoil of the 5.7 round. As with the 3x magnifier, I really like the QD mount that includes an Allen screw to adjust tightness of the lever. I probably wouldn't use this style of mount on a gun with more recoil, but the AR57 should not be a problem. Given the price of other options, for an occasional shooter like me, this sight is a GREAT value.
