[QUOTE="LouBoyd, post: 769050, member: 9253"] If you simply put a circular aperture centered over the objective lines of any rifle scope it will reduce the exit pupil diameter which has the effect of limiting the maximum parallax that having one's eye off axis can produce. It will also dim the apparent image brightness if the exit pupil is smaller than your eye's iris and with a very small aperture reduce the optical resolution. It does actually work. Using a scope with a objective focus, properly focused, works much better. [/QUOTE]
