Overview
"There are actually very good reasons they took out the rapid-fire function even in the M14's used by the American Marines. With a fully-automatic gun, the user is easily knocked down from the recoil, and it becomes difficult to aim properly with the barrel jolting all over the place, and of course it is also very wasteful." -Daisuke Sato
