I can shoot my HW 85 ar 50 yds with the narrow front post insert, and swing the 1.5" spinner until I am bored. But with scopes, I usually shoot 6-9 power and not much more. I find I can shoot just as accurately. Also benefit from a better picture in the scope, and more forgiving eye relief and the eye box. My brother shoots aperture sights on a CZ 452 trainer, and I found it real easy to group well. But the rimfire flies fast and flat, with less locktime.
