The M-16 series of firearms come with a caution regarding water in the barrel. If you shoot them "wet" they may burst.

"uring testing in March 1958, rainwater caused the barrels of both the ArmaLite and Winchester rifles to burst, causing the Army to once again press for a larger round, this time at 0.258 in (6.6 mm). Nevertheless, they suggested continued testing for cold-weather suitability in Alaska. Stoner was later asked to fly in to replace several parts, and when he arrived he found the rifles had been improperly reassembled. When he returned he was surprised to learn that they too had rejected the design even before he had arrived; their report also endorsed the 0.258 in (6.6 mm) round. After reading these reports, General Maxwell Taylor became dead-set against the design, and pressed for continued production of the M14."

No, I don't know why this effect occurs. I do know that I was warned NEVER to shoot the rifle with water in the barrel. The "procedure" after fording water is to aim the barrel towards the ground and allow it to drain.
