    well watching what happened,the explosion of the projectile causes the bolt carrier and the buffer to go rearward.if the buffer tube is filled with water,the gas can go nowhere but up,blowing off the top of the receiver is one scenario.

    Yes. I keep all of my guns barrels taped the entire hunting season. I take it off after. As I said earlier, it is not just for water. Lots of other debris can find it's way into a barrel. This has saved a couple of hunts where rifles have been dropped and landed muzzle down in mud.

    I don't think a few drops of water in a barrel are going to be dangerous. The military has been fighting battles in jungles, rivers, and rain for as long as we have had rifles. But it can't be good for anything. Tape is an easy cheap preventative.

    I have seen.pictures of guns with busted or blown receivers and barrels from water,snow and mud. I would not roll the dice on this one.

    This is a great thread-especially considering it must be monsoon season down south this week. got soaked at the range and wondered this myself. i guess one just needs to make sure the ammo stays dry..? i reckon wet primers are probably not a good thing:)

    Firing a submerged gun is a completely different thing from firing a gun out of the water with a significant amount of water in the bore. A submerged gun has water pressure all over it as well as inside it. A gun in the open air with water in the bore has a big 14 pounds or so of air pressure on the outside and an obstructed bore on the inside. It is pressure differential that causes the problems with water in the bore. The amount of water in the bore and the pressure the cartridge is working with will determine whether the gun fires safely, ends up with a bulge in the barrel, or destroys the barrel, the action, and/or the shooter. The Army issued plastic caps that covered the muzzle and flash hider on M16s when I was on active duty to prevent damage from bore obstructions like water, mud, ice, and snow. BTW, the smaller the bore for a given pressure, the more likely it is for water to cause problems, in my experience.

    Odd, I couldn't find your video of it in YouTube.

    I managed to pick up some surplus plastic muzzle caps. Great fit on M16/AR16 pattern barrels with muzzle devices attached. Made by a company call Caplug. Seen their work in non-firearm products too.

    That video linked by Sam1911 is for a youtube channel called SmarterEveryDay, and he does a great job giving us gun guys a good reputation with academic types.

    I've always heard that condoms have been used over muzzles for many a year. Wasn't that a WWI trick?

    an AR should have a little hole in the screw that holds the buttplate on so water can get out when it is fired

    It depends. When in wartime there is no timeout for weather. When given a choice opt on the side of safety.

    In my case I don't think muzzle covers are an option, I live in Uruguay and in the middle of nothing. So I guess I will tape my gun barrels. Here even condoms would be hard to get. Last night and today in the morning it rained 100mm. That's a lot! And there was a huge thunderstorm. We went hunting last night but we came back home because of the lighting.

    The difference in safety equipment is because HK knows that the Colt will fail and their HK won't. This is a post production video of previously conducted tests.

    The video explains the test A parameters include submersion with an open bolt and closing the bolt while under water.

    +1 for using tape (et al) to cover the muzzle! I have used electrical tape over the muzzle ever since the day we came in from hunting and my buddy ran a cleaning rod from the breech of his 300 mag and had to force out a 4" piece of branch that had gotten stuck in there.

    Considering some of the dismal conditions the Army had me in, yes. At least m16/m4's

    It can at firearm pressures.

    The problem is that it acts like plug and adds mass to the bullet at a place in the barrel that may not be as strong as the breech end.

    Water can be compressed? that's news to me.

    Go to your local drug store and the bandage section. Look for finger cots(condoms). Used to keep dirt and water out of wounds. Will fit snugly over rifle or shotgun muzzle and ruptures when shot through.

    I wish it could there would be engines running on it then, after watching video of shooting guns under water I will not use a speargun anymore lol

    Indeed liquids and solids are compressible, however the pressure needed is very high. I am not sure if those pressures occur in a barrel without doing the research, but I do know for sure firing with a barrel full of water is not something you really want to do on purpose. Your gun may handle it just fine, but why risk it?

    A balloon will slip over a shotgun barrel and stay seated just fine (smaller balloons will stay on a rifle barrel too). Keep a few in your gun case if you plan on being in the rain a lot.

    Umm...no, I'm afraid not. Your supposition here is all wrong. And it's an error of magnitudes, as well.

    That 14.7 psia difference means absolutely...nothing. Outside of a submerged environment, the pressure inside the barrel is still exactly the same as the pressure outside the barrel...namely atmospheric pressure. If you submerged the gun in 33 feet of water, the pressure inside the barrel would be two atmospheres...and so would the pressure outside the barrel.

    The overpressure differential when fired submerged is exactly the same as the overpressure differential in the atmosphere for a barrel full of water, because the static pressures are equal inside and outside the barrel. It's kind of like the question I used to ask young submariners in the Navy: if we double the atmospheric pressure in the submarine, does that mean the submarine can dive twice as deep? The answer is "NO"...the submarine can dive 33 feet deeper if you double the atmospheric pressure inside.

    Even if you held the barrel of the gun vertical, that pressure of the column of water at the bottom of the would still be negligable. 20-plus inches of water is an insignificant amount of pressure when compared to the 33 feet required for a column of water to reach 14.7 psi at the bottom of the column.

    The danger comes solely from the presence of an obstruction, namely that provided by water, in the barrel. Water does have an inertial component to it and, when struck with sufficient speed and force, does exhibit some characteristics of a solid, what with it being an incompressable fluid.

    CAN firing a gun with a barrel full of water cause damage to the gun?

    The answer is "YES".

    WILL firing a gun with a barrel full of water cause damage to the gun?

    The answer is "DEPENDS".

    That "DEPENDS" encompasses a wide variety of factors, including (but not limited to), barrel thickness, barrel shape, barrel construction (including design and materials), type of ammunition fired, velocity of ammunition fired, breech construction, etc.

    Firing a modern small caliber rifle under water? Probably not. Lots of videos on youtube to support this.

    Firing a small caliber pistol under water? Again, probably not. Lots of videos on youtube to support this as well.

    Firing a large caliber magnum pistol underwater? Maybe. Haven't seen any such videos on youtube...perhaps because people aren't willing to drop the cash in the risk. .44 Magnum, TC in various high powered calibers...that kind.

    Firing a high powered rifle under water? Maybe. I suppose this depends on one's definition of "high powered". Personally, I don't consider the .223 to be such a cartridge. 30-06, definately. .50 BMG, definately. But I haven't seen any such videos of these calibers underwater.

    Firing a shotgun underwater? Definately. Very easy to see why, when you consider the large internal barrel diameter and thin barrel walls when compared to a rifle barrel.

    Bottom line:

    Don't do it just because you think it's safe or someone else has told you or shown you that they've done it. Barrel obstructions aren't joking matters, whatever the source.

    Drain the barrel and practice good habits to keep obstructions from happening.

    ;)

    Good idea, except that my local drugstore is 25km away. Anyway I have electrical tape.
