Andy, or anyone else for that matter. At 57 my eyes leave me diminished when shooting iron sights. I have aperture rear sights and the fronts are the original Marlin brass beads. Is it predictable that a front blade would be sharper or easier to shoot. If so, just a plain blade or one with perhaps a white vertical stripe? I don't want to go to a scope as a scope would take away from the appeal of the gun. However it would be nice to have a better idea of hit probability. Apertures almost do what I ask of my lever guns, just want a little more. Thanks guys, Steve.
