I'm going to bump this, because I'm considering this sight myself. I looked at one yesterday at Outpost Armory (Ronnie Barrett's place) and they had a great deal on it. It seems to be light enough (I have a GII Lite Hunter with nothing added except Troy back up sights and a steel gas block to mount the front sight) to fit in with my light rifle plan, and seems to have good clarity, as well as reasonable adjustability. I do not need a mega buck sight for this rifle, it is not s long range sniper rifle, just a good solid rifle that can serve as a medium range semi auto target rifle, a medium range hunting rifle, and an MBR. Are there any known problems or real shortcomings concerning the Burris AR-536? Is there something better in the under $500 price range that offers light weight, a 1 MOA or smaller dot, and decent function as a close range red dot sight and a medium range optic?
