Is there really anything that hasn't been done with an AR? They're like a big boy's Lego set. If I were to start an AR company it wouldn't be to make the same thing that 20 other companies are making with a different widget on it! Someone really needs to update the AR platform into something different. Design an AR for the 308 class of cartridge that is on a smaller frame than the AR10 and you would have something.
