Just really wondering why all the "hype" on AR"s? What exactly makes it such a bad@$$ gun? Cause the police and military uses it? Everyone I've ever known to own one says it's kinda like owning an old Harley. Constant work & maintnance. I've got a mini-14 that I feel is about the same gun, it's a straight shooter and never fails nor needs maintnance. Am I missing something?
