RE: Which AR?
I second that from Big Bulls. I'm the farthest thing from a ballisitics expert, but I have seen a lot of reports that back up what BB says. Some day I want to have a pimped up AR as my main property defender. The other benefits of the AR is the higher capacity and less recoil when trying to stop the BG who was dumb enough to invade your property. Best luck and God bless.
