Gary, you're pretty spot on on your answers. If someone has a vision issue with iron sights, though, we do encourage him to use a scope - my LTR is currently sporting a Weaver K7 scope for that very reason.
I'm not sure a scope will help me, but I'm going to try with Iron sights. I really need to sight in my Tech Sights AR-15 style sight. Rather, I need to have someone show me how to do it correctly.
