I love my AR as well. The AR-10 is a cool gun, but .308/7.62 really is overkill unless you're hunting with it or doing some decent distance like 500m-700m. The standard .223/5.56 is enough for what most people use an AR for...defense and mostly target work. Sure you don't get the 'I'm a badass' element as much with it, but meh, that's overrated. Function>form, all day.
