M27 IAR (Infantry Automatic Rifle)
Background Info: The M27 IAR is intended to replace the aging and more bulky M249 SAW (Squad Automatic Weapon). It is designed to be lighter, easier to use, and faster to deploy with, based off the all to familiar H&K 416 Platform. Why? Well most troops know how to use AR-15 styled rifles and switching over to an entirely new M249 requires training and more time.
