So, I'm reading about people shooting tight groups without optics at ranges well in excess at 20 yards+. I have a question about that: If you are forming the sight picture by focusing on the front sight, how do you even see what you are shooting at? When my eyes are focused at something 4' in front of my eyes, by the time you get out to 60 feet, it's crazy blurry out there. Is there something else to do when aiming without optics at these ranges other than just focusing on the front sight? Any tips I should know?
