I just picked up a new Gen2 G23 Eotech Magnifier at a gun show this weekend. I have had the 512 for about three years but and have always wanted the 3X to go with it but the price always stopped me. I had a weak moment at the gun show and purchased one and I really like. I still think they are overpriced but it is awesome. Mine had an inspection date of 2/12/2012. It has the same new mount that comes with the G33. It is a quick disconnect and to flip it you just grab it an flip it open or flip it closed. There is no plate to unlock it. Spring pressure keeps it firmly open and closed, it is very solid. I have a troy front sight and a matech rear sight but the matech is a little to tall folded to fit under the 3X so I ordered a Troy for the rear also.
