The World in Four Calibers

Have you ever wondered where your favorite guns from games and movies originated? Have you ever wanted to know why the AK-47 is so popular? Did you know that the M16 actually works just fine (now)? Did you notice that most military firearms today use only a handful of different calibers? Find out why so many nations use the same weapons, how the assault rifle and submachine gun were born, how armies came to choose the calibers they use, and which guns killed Osama bin Laden or Bonnie and Clyde. Brian Craig takes a light-hearted look at the last hundred years of small arms development, weaving an entertaining saga of the guns that shaped modern war!
