To me, it sounds like the AR platform for hi-cap mags and the red dot for quick acquisition is the way to go. I'd stick with the .300BO before you buy a new upper. I'm with ya on not being a big AR guy, but I got my wife a PSA .300BO and I really like. May have to go field test it for her. If you just plain don't like the red dot, then only get a 1-4x scope for what you are talking about doing.
