Scopes are good for better placed shots AND for people that have poor vision. I wear glasses and cannot shot ethicly with open sights. My eye sight is that poor, even with glasses. No matter what I have not found open sights that I can see clearly. They can easily have the regs state that you can only have a max 4 power scope. I don't know many people that can shoot over 150yards with a 4 power and be accurate any ways.
