I'm no expert but i can't see why immersion in water would have the same effect on the weapon as plugging up the muzzle. If you look carefully the failure also causes the magazine to be blown from its position indicating the gases caused on firing the weapon failed to propel the bullet up the barrel and were forced to escape wherever it could, in this case blowing out the magazine from its housing and fracturing the reciever above the cartridge ejection position. I can see that it would possibly cause a failure to cycle the action, maybe, but to cause this sort of complete structural failure because of water in the weapons barrel seems a bit odd to me.
I've seen an M-4 buried in sand and immersed in water and then fired and it still worked. Really depends on the circumstances I suspect.
"Korea has not been the only battle ground since the end of the Second World War. Men have fought and died in Malaya, in Greece, in the Philippines, in Algeria and Cuba, and Cyprus and almost continuously on the Indo-Chinese Peninsula. No nuclear weapons have been fired. No massive nuclear retaliation has been considered appropriate. This is another type of war, new in its intensity, ancient in its origin--war by guerrillas, subversives, insurgents, assassins, war by ambush instead of by combat; by infiltration, instead of aggression, seeking victory by eroding and exhausting the enemy instead of engaging him. It is a form of warfare uniquely adapted to what has been strangely called 'wars of liberation,' to undermine the efforts of new and poor countries to maintain the freedom that they have finally achieved. It preys on economic unrest and ethnic conflicts. It requires in those situations where we must counter it, and these are the kinds of challenges that will be before us in the next decade if freedom is to be saved, a whole new kind of strategy, a wholly different kind of force, and therefore a new and wholly different kind of military training."-President Kennedy's Address at Graduation Exercises of the U.S. Military Academy, 1962

"The reason I'll be released is the same reason you think I'll be convicted. I do rub shoulders with some of the most vile, sadistic men calling themselves leaders today. But some of these men are the enemies of your enemies. And while the biggest arms dealer in the world is your boss - the President of the United States, who ships more merchandise in a day than I do in a year - sometimes it's embarrassing to have his fingerprints on the guns. Sometimes he needs a freelancer like me to supply forces he can't be seen supplying. So. You call me evil, but unfortunately for you, I'm a necessary evil."-Yuri Orlov, Lord of War

"Of all the weapons in the vast soviet arsenal, nothing was more profitable than Avtomat Kalashnikova model of 1947. More commonly known as the AK-47, or Kalashnikov. It's the world's most popular assault rifle. A weapon all fighters love. An elegantly simple 9 pound amalgamation of forged steel and plywood. It doesn't break, jam, or overheat. It'll shoot whether it's covered in mud or filled with sand. It's so easy, even a child can use it; and they do. The Soviets put the gun on a coin. Mozambique put it on their flag. Since the end of the Cold War, the Kalashnikov has become the Russian people's greatest export. After that comes vodka, caviar, and suicidal novelists. One thing is for sure, no one was lining up to buy their cars."-Yuri Orlov, Lord of War

Quote:In some (rare) cases the liquid left in the barrel causes so much friction that the round itself functions as a plug.
Really, i didn't know that. That's a bit worrying.
I dragged every bit of my rifle through alot of water and just concerntrated on keeping the magazine dry. If i'd known i would have been a bit more careful.

To be honest with you, I've only heard of a very few occasions that this could have happend. The odds that they managed to capture this particular problem on video, seems very small. So I wouldn't be surprised if something else contributed to the backfire.
I,.m not sure realy about this,But...
Reacently i watched on Military channel(weaponology) that H&K416 is the most durable weapon ewer created,,,,,,,surpassing awry other by far(including the famous AK 47)....
It fired in sand,watter....without any problems.....and his colling mechanism is unique. After firing 150 rounds or so the guy tock the gun apart with his bare hands without any danger of burning himself by taching the barrel or any of the internal components,,,,,,They were not eavn warm.
Interesting weapon i mass say after what i saw.....

Quote:There are various reasons why the HK416 can repeatedly survive and come out fully functional from both OTB A and B tests. Little of it has anything to do with the op rod gas system. The major damage to the weapon does not come from the gas tube. If that was the case then there would be damage to the hand guards. The damage to the weapon comes from the ruptured case and bolt head and the high pressure gases that then escape in the reverse direction of the barrel into the receiver as seen on the video. You also will note that the magazine blew out of the competing model. This is also seen in bores obstructed by logged projectiles ("pop and no kick"), mud, etc. One of the two tests (where the weapon is immersed with the bolt already closed) is much more severe because an air bubble remains within the bore increasing the "back pressure." The OTB variant of the HK416 survives this test over and over again (dozens of times without damage of any kind) because of the nature of the HK cold hammer forged barrel and material used in the barrel and bolt head, the vent holes in the bolt carrier and stock and a little trick to limit the travel of the extractor under excessive pressure. Most often the bolt heads "go" at the extractor cut out. That is why the G36 has a fully supported bolt face and with minimal extractor clearance cut. No room for that exactly in the HK416 receiver but obviously it performs just fine w/o it. As for vent holes on the stock causing issues in a dust test. Not sure on that one, whether it's been tested as such yet. Unlikely the APG test samples had the optional stock vent holes. However keep in mind that in the surf zone near the beach there is plenty of sand and grit suspended in the sea water that finds its way everywhere the water does. Obviously that has not been an issue because the OTB HK416's have been working very well where issued in that environment.
