I think the real problem with the AR is the magazine. I have shot about 4 in the last year. I put a hole in them so nobody else tries to use them. The magazine on an AK is built like a tank. The most catastrophic malfunction on the M4 is when a round jumps up over the bolt. You have to use a pocketknife to get it out, but thats why they give us a backup pistol. For as long as US GIs have been duking it out at close range they have all carried three weapons like Samurai. Rifle/shotgun, pistol and a knife. Owe, and somebody needs to tell that elderly gentleman we don’t use full auto for regular troops anymore. Standard practice is two rounds at close interval, from the shoulder and with optics.
