We could say we're just talking about the scary looks of it - it's black, has accessory slides, flash suppressor, folding stock, curved clip, No Fear stickers, etc. BUT the context of the conversation is something designed with a combination of high power round, large magazine capacity and high rate of fire that makes it best suited to kill as many humans in the shortest possible time-frame. Remove any one of those three and you're back at a hunting rifle. Although nobody is going to make a bolt action rifle with a banana clip.
