so you say you want an AR that is good for personal defense and will go through a barrier, in this case I can think of nothing better than the .50 beowulf, I know it may seem a little overkill, but I see it like this, there is a big difference between self defense and hunting, its not like your trying to save the meat of a perpatrator. Ammo may not be real easy to get but you should be able to buy or reload plenty for your needs. If I were buying or building an AR for personal defense this would be my go- to caliber, but that is just me. If I am protector me and or my family I want a one shot stop.
