Only thing I have really done to my Athlon is mark certain parts of the turrets with day glow orange and add a sun shade form them. When It first cam out, they wanted 50 bucks for the shade. I found it on line for 29 bucks and bit. LOL!It really is helping in the very early morning and very late afternoon. Such times of day really separates the men from the boys in optics. The Zeiss I have has no shade, and NEVER flairs out. Love great optics!!!Knife
