The AK-47

The most-produced rifle in history, told against its own folklore: who actually designed it and what Zaitsev contributed, why the first stamped receiver had to be abandoned, how to read a rifle and tell the makers apart — and a full parts-kit build on a milled Yugoslav-pattern receiver, headspace to retention groove.
