NC-Mike:
What you want a .223 semi to do for you is totally....up....to...YOU.
However, how the weapon appears IS an element of FUNCTIONALITY. If you want to be able to stand on your porch, holding your bushy, and scare the zombies over to your neighbor, then an AR does that job MUCH better than a mini.
If you want to walk down the street with a semi .223 on your back and not draw that much attention to yourself...then the mini is better.
Case in point: you will find more gun laws against an AR than a Mini. "Functionally".. they are about the same...right?
Consider a Ferarri - bright, red, kicks A$$...but it looks like its doing 100mph sitting still. Put it next to a grey dodge hemi R/T. "Functionally", the Dodge will keep up with it 80-85% of the time, but which car gets most of the attention?
That was my point in my earlier post. OVERALL, the mini for ME, makes more SENSE. However, what makes sense for me, what I want from a rifle, etc.... may not make sense for you.
So as someone said earlier, there will always be room to debate this topic.
Mini - less finicky; will eat what you feed it, easier to clean, blends with the crowd,.etc.
AR - outstanding shooting performance, select diet, comes in 100 flavors, needs a regular bath, and stands out as a real show stopper.
