I agree about getting the RD as close as possible, if the gun permits that as my 590 does. The FF3 on the rib mount however, is very unobtrusive due to its very thin frame around the window. When I mount it, I’m conscious of the dot, but barely aware of the rest of the sight.
When we shoot clays, a few of us like to call out tough shots, for the other guys. One day I was shooting the Mossberg with the FF, and the trapper called a pair for me, followed by, “left handed?”. I gave him a dirty look then said, “okay”. Got ‘em too, to my great surprise. Hope to turn that rig on some foxes or yotes soon if I can get my leg sorted out.
