I have a couple of Bushnell TRS-25 red dots and like them. Plus they are very reasonably priced.
However, at the moment, and at age 72.5, I'm just shooting the red fiber optic bead on my Benelli M2 and it works fine for me.
Inside forty yards I line up the brass mid rib bead with the red fiber optic muzzle sight.
Outside forty yards, I stack them like a figure eight.
