In terms of shear mass, in straight numbers, the 7.62x39mm is far and away the preeminent battle rifle caliber in the world. With over 100 million AK-47 and its clones having been produced it’s not hard to see why. That’s not a misprint, and it does not include the VZ-58, SKS, or the slew of Eastern European and North American rifles, and the light machine gun RPK which uses the caliber. There is nothing more common than this guy. And why shouldn’t it be? Compact, hard-hitting at typical combat ranges, and all of the weapons which use it have proven to be supremely durable and reliable.
