I don't doubt what you're saying because I don't have any prism scopes. But I don't understand it either... position is position. Happy to understand where I am looking at wrongIf your using a scope you can do that no problem.
Prism scope different. I went out to range and yes you have to get up on the scope to get good eye box. My ar15 is easier as I ca shorten the buttstock.
Really when standing freehand it doesnt seem to be as prominent as it does when you are bench shooting.
Minor adjustment I just like a good set it and forget style. Prisms do that for me.
