Shooting Under Water

I have used condoms on the end of my M16, finger cots (small finger condoms which work better) and if you can find them, the plastic end cap (that every REMF seems to have). I have also used black electrical tape. These are more to keep debris form entering the muzzle, water will find a way to get in, ask anyone who has done any AmphibRecon course.
Any way you slice it, pull the bolt to the rear so the chambered round breaks the seal, point muzzle to the deck to facilitate drainage as you exit the water.

The condom trick is in a lot of movies, more an dirt and mud issue I believe. I read that Seals in Vietnam also used "mud plugs", basically a foam ear plug jammed in the muzzle. First shot blew it out.

Taping the muzzle is standard (moose) hunting practice where I go in Northern Ontario. Keeps the mud & twigs & ice & snow out. I'm really surprised they don't seem to do it in the military in Iraq with all the sand.
 
Sand and dust in the barrel really doesn't affect function, maybe that's why it's not very common?

A foam ear plug jams in my flash suppressor nicely. Not water tight, but would keept mud and dirt out.

I have done it in Central America, Asia and Middle east, but mainly to prevent a 'mud plug'. A bit of dust or sand will not hurt, a small pebble maybe, an accidental muzzle into the dirt will create a plug, don't think that's a good idea...KB?? Used to tape over the holes in the handgaurds during winter/snow Ops too.

Practically I don't know how you can ensure there is no air pocket in the barrel due to the small dia. of 556 bore and the surface tension of water. In two words....DONT TRY unless it is someone's else gun:D

#### the weapon while under water,it will "break the seal" and allow water to flood the barrel. And YES do it with someone else's weapon..or an issue one.:)
 
So if it can be done, how is accuracy under water? lethality? velocity? I had assumed the bullet would disintegrate as most rifle rounds do when you shoot into water.

Also, what's wrong with that dude's AR? I can see something outta place, but I would like to know exactly what happened.
 
I find it makes lots of bubbles,...which then start to overflow onto the bathroom floor.
 
hmmm good point. Water would cause more resistance on the bolt group. i wonder if the action would cycle properly underwater.

I sure as hell would like to see someone fire a gun underwater. I had no idea that it was doable.
 
Didn't you guys see Mithbusters ?
They fired a few rifles into the water (not under the water) including a .50cal and all the bullets lost all there energy in about 5 feet.
But maybe it's different under the water ???

If I remember correctly the only rounds that penetrated the water were low velocity. The .50 bmg and the 5.56 fragmented when they hit the water. It most likely wouldn't shatter the bullet being that it is fully submersed but I have been proven wrong once already in this thread.
 
I think this would be a great one for the Myth Busters to try out.

I wonder if the bullets would fragment the same if they were fired under water? I can see why they did when they hit the water, maybe they'd go further if they started in the water?
 
Well about the Mythmusters bit, they fired into the water and not in the water.
Fireing into liquid is quite similar to firing into high density material and that is why all the jacketed rounds disintegrated, even the big fifty.
Firing under water is different since the projectile is immersed into a body of water. It's moving in it instead of entering and then continueing. There is no shock to the projectile upon contacting the water, only very heavy drag. Bullets under water don't usually travel further than 10-15m with guarranteed lethality.
Tried it in my friends swimming pool one lazzy afternoon.

Simple physics should suggest limited range with limited velocity and energy as compared with normal shooting...(out of the water :))
 
I wold like to recomend a dvd caled Underwater Shooting with Leeny Migill
It may clear up some missunderstandings from the armchair experts.

Lenny is an Idiot..... Watch the DVD and you will see wat I mean.
 
For all you guys that like to take guns into the bathtub.There are several guns that will fire underwater (conventional guns).Steyr AUG,Steyr TMP and SPP and Glocks 9mm and .45 acp..To shoot any gun underwater,you should not use any HP or Softnose bullets and the velocity has to be subsonic.You guys shouldn't have any problems hitting your intended targets at bathtub length because lethality and accuracy under water is about 3m.Happy Shooting-Rainer
