On a sidenote, I ran a combat assault course in a light rain, crunched the rifle into the ground and dirt, flipped on my back to go under barbed wire right into a deep puddle (my mouth was sticking out, but everything else, including my rifle, was mostly underwater) which was normally dry and crawled through a bunch of funky wet bushes, and yet even working with blanks, (notorious for jamming with low power in them, unlike live ammo) I only had a single jam, quickly fixed with a tap rack bang (the M16 version)..... The M16 is unreliable, huh? yeeeeeeahhhh..... it can be, but not if you do your part. This was Fort Knox in the summertime too, so it was 95 degrees and 90 percent humidity during all that. Hydrate or die... we had a guy pass out.
