re: Soldiers Hate the M4 and M16. The Pentagon Is Finally Doing Something about It.

Mine never malfunctioned in combat

In fact, I can think of very few malfunctions I’ve had with the weapon even in training. And most of those have been from faulty magazines.

I would add that the average engagement distances in Afghanistan have been 300 meters or more so a more powerful round could be useful. But then you run into the problem of weight.
