There is a golden rule to the soldier - he doesn't like anything that adds even an ounce of weight to whatever he has to carry around.
With that said, if you travel the marching roads of Fort Lewis and bother to look in the bushes, you can find whatever you like, from fully loaded M-16 magazines, to grenades. Soldiers apparently chuck em on their marches to lighten the load.
Also, while this system may have some issues still from old tech, consider it rev 1. The M-16 was good, but wasn't all that great a tool till the A1 version.
