Trijicon RCR: There's such a thing as too low on an optic deck height
This video explains that the perceived larger window size on optics like the Trijicon RMR HD and RCR is not due to a larger actual window, but rather a slightly taller optic deck height. This increased height allows the optic to clear iron sights more effectively, improving the sight picture without the irons obstructing the view.
