My first experience in using an M16 was in BUDS training, class 49 in 69. It was a steralized
gun left over from the Kennedy misadventure in Cuba I was told. As long as I kept it clean
it worked fine. The ammo made the difference, some of it was almost as bad as black powder. I think we got better ammo because it was always getting wet in training. As long as it was used up in a few days, it would work after being dunked in fresh or salt water.
