It's a trijicon! - Trijicon RMR Type 2 RM01 LED 1x65mm 3.25 MOA Red Dot Sight

This definitely should have been my first purchase. Tried to save some money by getting a Holosun. Sent it back because the dot was blurry and had this spiderweb effect casting off the dot. I pushed aside my cheaper mentality and much happier now. Dot is crisp and clear, with and without my glasses. I've seen reviews that some do not like the auto function, but I do. The setting of dim and brightness are what I would have put them at myself anyways. The speed that it adjust is pretty quick in my opinion as well. Buyer beware: you get what you pay for.
