AK-47

The AK-47 is the most popular assault rifle of all time. It was developed in 1947 in the Soviet Union by a World War II veteran. The rifle is easy to manufacture, maintain, and operate. It will tolerate dirt and abuse and still work well. It is somewhat slower, heavier, and less accurate than the American M-16, but fires a heavier round and is cheaper and way simpler to use.

The rifle is one of the most universally-recognized shapes around the world and is on some flags.

It is built mostly out of stamped parts, which is what makes it so easy to manufacture.
