My son recently gave me a nice older Sure Loc sight. It has monofiliment crosshairs in the sight. It came with a nice case and in the case is a glass scope which I don't use and really don't want to use. My eyes are ok, I just can't see the crosshairs good enough to shoot well. I dabbed some white paint on the crosshairs but still need something else. I am familiar with hunting fixed sights but not this type. Does anyone have any recommendations? Thanks in advance for any help.
