Like the view - Trijicon OPMOD SRO Adjustable LED Red Dot Sight

I have several RMR's and love them. But a top loading battery model that has a larger window and a 2.5 MOA dot was enough advancement for me to buy another. After several sessions on my rifle the dot size in accuracy was obvious. Typical groups shrunk by about .5". Not much until you shoot at 300 yds. The larger window is faster and easier to see the "field" with both eyes open. Besides, it's a Trijicon.
