Didn't work so great in Iraq and Afghanistan. The distances were to far for the 556 to be very effective. That's why the M14 made its appearance again. M4 and A4 are out ranged and out gunned at 500 meters for the avg infantryman vs Dragunov's and other high power rifles they used.We've been using 5.56 for 20 years to kill a lot of guys at that distance and beyond. The m4 or m16a4 with acog became a very lethal combo. My issue is just sheer cost of all this. Why isn't this across al the branches? And is it really effective when even most combat units qualify once a year.
A lighter more powerful rifle than a M14 is welcome news.
