Kalashnikov, father of the AK-47 assault rifle is dead at 94.
He was a giant in light weapons design, not quite at the level of John Browning or but certainly at the level of Eugene Stoner.
He did not produce the first mass produced assault rifle, that was the German StG-44, but he created a truly inexpensive (Once they got the stamped spot welded sheet metal receiver perfected with the AKM) weapon with reliability and simplicity that are still the standard. (Not so much on accuracy).
It fit the doctrine of the Soviet military, as well as the numerous irregular “liberation” movements throughout the world, and something in the neighborhood of 100 million have been produced to date.
Much of this production was because licenses to manufacture were freely and fully available to any government that indicates some sort of favor toward “international socialism”.
In a very real way, this was an open source licensing model applied to steel, wood, and lead.
As such, it is doubtlessly responsible for more deaths than any other military firearm in history.
