How do you all have your iron sights set up? For my slug barrel I shifted the rear sights all the way up. When I look down the sights the white dot is what I focus on and I try to place it in the middle just like in the picture below. What's annoying is that I had to push up the rear sights all the way to the top. It's set at 50 yards. Should the white dot be up higher? How do you all set up your iron sights? Thanks everyone!!
