Ian V. Hogg Guns and how they work

Marshall Cavendish Ltd., 1984. - 188 с.
This book is about how guns work. Leaving aside, for the moment, the moral and psychological aspects, whatever else you may think of firearms you have to admit that they are remarkable mechanical achievements. Just consider, for example, what goes on inside a machine gun twenty times a second - the cycle of firing, unlocking, extracting, ejecting, reloading, relocking and firing again, for thousands of rounds on end.
