Maybe the barrel filled with water before the fourth round was fired.

I think it took that many rounds to pump enough water into the gas system. The bottm of the BC blew out from hydraulic lock. JMHO.

I'm guessing that the process started with the first round...

Something smells fishy.

I think it's a trap.

Buffer tube filled with water and wouldnt let the bolt unlock?

Since we have only one data point for this "experiment" we can't tell if this was a fluke or not.
We need more data to answer this burning question... RedGoat you got 4-5 ARs we can borrow to answer your question, I promise to give them right back when I'm done.

None of the above

It was not engineered to fire underwater ---
thats all.

pics?
found the other thread

I personall think "who gives a fuck". He fired it underwater, apparently it broke. I seen those gay army commercials that show guys popping out of the water ready to shoot. People do stupid shit. I have posted my mistakes on here. Glad he is okay and lesson learned. hopefully his example will show many people that have wonder such things, what happens and now no one will get hurt. Lay off the guy unless you are guilty of no stupidity ever.

He should check inside his barrel, maybe rounds didnt make it all the way out and progressivly backed up, I have seen it with sand.

I dunno either.

If the chamber is closed, and muzzle covered?

Might take a while to leak enough.

How can the barrel fill with water if gases are being expelled in 1/4 sec intervals?

TRG



If there is any air in the BBL it will blow

if it has no air at all --- it will fire but the presures are high , real high, you will get away with it ??? number of times then bad stuff will happen.

So a piston fired AK or DR200 would not have exploded?

TRG



In any event, I though the THEORY behind not firing rifles under water was that water in the barrel would act like a "plug" causing a blowout because the bullet couldn't move through the barrel fast enough and the gas pressure would blow back into the bolt/lower - not that water got into the gas tube.

now, that might make sense if there was a delaye between 4 and 5.

4 did not exit, five struck it?

Why would 4 not exit if 1,2,3 did?

TRG



He hasnt replied to that thread in a while has he? We should ask him to check the inside of the barrel. I would say maybe even 1, 2, 3 didnt make it, just got stuck, increasingly closer to bore, then by last it got close enough and boom. I have seen Marine Corps saftey sheets that talk about up to 6-7 rounds with sand, and seen it happen once, but the guy only had 2 rounds stuck in barrel.

You can't "bumpfire" under water.


Think about it.

Repeating what I read in a an old guns and ammo mag

they shot a gun underwater and it functioned once -- showed signs of high pressure thats all

they said if it air had been in the bbl it would have blown up ...

I'm guessing the process started with a moron.

Gun blowups resulting from bore obstructions invariably split the barrel but generally don’t blow the receiver apart. The damage I saw in the photos looks like a typical overpressure. This would suggest that a barrel full of water was the cause of the blowup. If your interested P O Ackley in his Handbook for Shooters & Reloaders describes experiments he did to see what it takes to blow up a gun using gross overloads of powder, bore obstructions and wrong cartridges. Great reading and photos, it puts to rest a lot of gun misconceptions on what does and does not blow up guns, I highly recommend reading it.

The buffer not moving has nothing to do with the blowup, it just turns a semi auto in to a bolt action. No change in chamber pressure.

If I did not have pics in the thread to show what the result would be, I would try bumpfiring under water. If anything the minimal amount of water resistance would just make the gun bump slower.

TRG




SInce the purpose of bump firing is the rifle "rocking" on the rear trigger finger I doubt it can be done.


Really. As for as a fast finger underwater...well, I never fired a gun underwater so wtf do I know.

Everyone here seems to have forgotten the scene in the movie where Mel Gibson shoots the bad guy under water with the AK....

It was on TV so I know it can be done
