Mechanical Principles of Small Arms

This Army Pictorial Service training films does an excellent job of explaining the fundamental mechanical principles of small arms through the use of oversized physical models, not unlike the Hamilton Watch Company film I referenced in an earlier post.

The first half takes us through all the basic operations of a single-shot magazine-fed firearm like a bolt-action rifle.


While the second and third cover semi-automatic and fully-automatic actions.
