The battle between AK and AR has oulasted the Cold War. It has been debated ad nauseum online and shows no sign of having a clear winner. So enough about those two rifles. My question is beside the two aforementioned rifles the AK and the AR, What is your favorite modern battle rifle? Let's define "modern" as WWII or later conflicts. Base your answer on COMBAT use NOT shooting TARGETS. Feel free to expalin the reason for your selection.
