Just goes to show - it ain't the rifles, its the troops that win the battles.
My son didn't have any real experience from an urban combat perspective, but he was studying mechanical engineering and was intrigued by the AK47 and it's variants. As he said "The AK does have its weaknesses, but I do prefer its balance and handling qualities to those of the M16 series." He hated cleaning the M-16, thought that the direct gas action was the worst feature of the gun, though he liked the accuracy. He scored a "perfect" at 500 yards in boot camp on a windy day.

I do wish the 6.8 SPC or a 6.5 MM cartridge woulkd be adopted. And a rifle like the AR-180 or something simliar would be more reliable.
