That was one guess. Other guess was a seriously overcharged round, possibly combined with failure in the metal.

Does oil vaporize under the pressure and explode?
>>28879729
no, it creates a hydraulic pressure spike. Water and oil don't compress as well as gasses.
>>28879729
Imagine how bad your car's hydraulic brakes would work if we bled them dry and made them run on gasses. It's like, the opposite of that.
>>28879579
Squib? My first guess.
>>28879859
I don't think a squib would destroy the fuck out of the bcg and leave the bolt in the chamber.
wolf is dirty ammo, the steel doesnt expand in the chamber all the way to create a perfect seal like brass does. after a while, carbon builds up in the chamber, im guessing this contributed to an out of battery detonation, where the cartridge was fired while not fully seated in the chamber
>>28879746
>imagine how well your gun's gas system would work if we lubed the gun up and filled the gas tube with oil
Yes, exactly this well.
>>28879936
the bolt face is still visibly chambered and in battery. >>28879867
>>28879957
i noticed that, but assumed the poster mocked it up for the photo? could have also been shoved in by the recoil spring after the explosion
>>28879988
I think a hydraulic pressure spike tearing some new holes into the BCG because the gas tube was full of lube sounds like the most accurate cause.
>>28879720
Is that guy in the pic is talking about h&k vid of bloving up the ar? I think you meedto habe the bolt carrier filled with water for that to happen.
>>28880265
>desperately clinging to shreds of hole that it's wolf's fault
It's clearly operator error.
>>28879988
>could have also been shoved in by the recoil spring after the explosion
How could it go back into battery when the BCG and receiver is blown apart and not able to correctly guide the bolt face to the chamber?
If it was oil in the gas tube, how would he have gotten through nearly a hundred rounds first? The round contaminated with pistol or shotgun powder sounds more plausible.
>>28880341
You don't know what exactly happened.
It could have been over charge.
What also could have happened was that he fired the gun a lot, was getting jams, then started oiling the shit out of the gun and accidentally or unwittingly, got some inside the gas tube causing this bullshit.
I wouldn't have thought of that if I hadn't seen it myself.
This guy at my range was having jamming issues with his AR, and his response to that was squirting oil into the open chamber. He didn't even take it apart, he just locked the bolt back and squirted a bunch of oil in there.
>>28879579
>>28879586
Wolf ammo, case solved. Notice how part of the bolt is still stuck in the chamber
>>28879720
WHAT! This is retarded. Water in the gas tube would not cause that. Water in the barrel and upper would.
There is not enough volume in the gas tube.
>>28880371
You're correct in that I do not know what happened. But if he did get oil into the gas tube, I would think that dinky aluminum tube would rupture well before the bolt carrier.
he shot a poorly reloaded round without experience and now wants to blame someone. proving kommandos are just white skinned nigros
>>28880426
yes, my flimsy hypothetical proves it
>>28880426

This is correct. Oil in the gas tube will rupture the gas tube, not the entire upper.

Except it does.
https://www.youtube.com/watch?v=AGwkHktkTxU
The US army has known about that since the 60s.
Which is why M16A1 manuals explicitly state to take extreme care to get all the water out of the gun before firing it after it has been submerged. It's also the reason SEALs liked simple blowback SMGs rather than gas operated rifles.
>>28880553
God, I haven't seen that video in years.
Unless I am mistaken, the Colt in your video fragmented the receiver (which is not designed to handle much outward fluid pressure), but not the bolt carrier, as in OP's post.

>>28880553
>Believing H&K garbage

>German techno music
The gas tube had nothing to do with that failure. It is water in the barrel, not the gas tube that caused the malfunction.
The piston just vents the water in the gap where the gas block and piston rides, that is why the H&K does mot fail.
The M4 fails because it creates over pressure because all of the water in the barrel cannot go through the gastube.
Also notice how quick he is shooting both rifles. That is because he wants to keep as much water in the barrel as possible. If he waited just a moment, it would not matter.
If you shot a rifle with empty barrel and a gas tube full of water and I guarantee it wont do anything.
>The US army has known about that since the 60s.
It has been known since the first rifles where invented that if you stuff enough shit in the barrel, there will be problems.

Fuck, unless someone here is actually a materials engineering major with a history of designing rifles, then we are likely talking out of our ass.
Assuming the guy did not fill his rifle with fluid at the range before blowing it up, what is the likelihood of Wolf replacing his rifle?
>>28880748
How about fucking common sense. The reason we put condoms on the barrels of our rifles. To keep sand and water and shit out of them.
The gas tube has zero \ nothing \ nada to do with it.
You can shoot an AR15 under water, does it KB? Obviously the gas tube is filled with water!!!
https://www.youtube.com/watch?v=0MA1IFKwdAQ
The reason he can shoot under water is because the pressure is normalized around the entire weapon. It is still a bad idea, but notice there was no KB.
Also the shorter barrel of the HK would keep the pressure lower, because there is less resistance.
>AM I THE ONLY ONE WHO GRADUATED MIDDLE SCHOOL HERE
>>28880773
Pretty much. I doubt it had anything to do with water in the gun, don't know how the fuck these autists got on that topic.

>>28880832
So?
>>28879579
>carbine gas
>16" barrel
well, clearly what happened is, over pressure caused the bolt to break and crack the receiver extension, which explains why the guy couldn't remove the bolt.
since it is carbine gas on a 16" barrel, the bullet was still in the barrel while the way over pressured gas was traveling into the carrier. since the carrier couldn't move back because of the broken bolt, the carriers chamber, being sealed off by the gas rings on the bolt, just kept being pressurized with no way to vent until it finally exploded.
this was caused by either a round filled with a fast powder(pistol) or by a squib round past the gas port and the next round having no where to push the gas.
my guess is a hot round, busted chamber, and a squib past the port.
there, i solved it now give me my prize.
>>28880796
you could literally weld the gas tube shut at my receiver end and it wouldn't blow up.

>>28880876

>>28879737
They do not compress at all.
>>28880942
Lets not. Remington actually makes some pretty good loads.
You'll get the amount they could worm out of in small claims court, which means that you won't see more than a compensatory amount unless bodily harm was done.
>>28880958
Oh yeah? What about water changing it's density .024% at pressures so high they have no bearing on this conversation at all?
>>28880960
Off topic, but I've also seen some shoddy loads for Remington on their 9mm UMC line as well. Granted, I haven't seen any crap on their rifle ammo so far.
I wasn't looking for a pay day. Just recommendation for a lost rifle. Again, assuming the owner did not fuck up here.

>>28880930
they could but it's only like $1,000 for the gun so it's smarter for them to just give the guy money for a new gun and recall that lot of ammo.
>>28880951
yes, when i replied to you i was talking about the gas tube being the only thing closed off, the bullet still goes out the muzzle like normally and all the gas goes with it.
now, if the barrel is blocked at the muzzle and the gas tube at the receiver, then the gas tube would burst, probably the barrel as well.
>>28880717
Frigg off, Randy no bandy, you great cheese burger gut walrus ass mutha fuckka.

however, i wouldn't mind an ass hair maid who is their to protect my anus.
>>28880930
Probably nothing stops them. They will likely fight about it. Some ammo manufactures have insurance for situations like this
>>28880989
if the gas tube is blocked there will be a condition of overpressure which is essentially the primary cause of catastrophic failure.
>>28881008
but if the muzzle is clear than the gas can escape back out the muzzle and nothing will happen.
i can block the gas at the receiver end of my ar and all that happens is i go from semi auto to single shot.
>>28881008
Unless there's another exit for the gas, say, the end of the barrel. Like he said, overpressure would require a squib blocking the barrel.
>>28881049
>>28881052
yes the gun would fire a round downrange but the gun is also not designed to operate without the gas system intact.
how fucking hard is this to understand?
go block your gas system and fire it, let me know how that goes for you.
>>28881063
>gun is also not designed to operate without the gas system intact.
Of course it fucking won't, it will be single shot. Otherwise, as long as the bullet leaves the fucking barrel, there is no excess pressure past what the gun is already designed to handle in normal operation.
You do know there are receivers with adjustable gas taps at the receiver end right?
>>28881091
Yeah, and OP's gun didn't have any such thing installed, so the overpressure went full force into a tube full of lube, and cause the failure.
>>28881091
>Otherwise, as long as the bullet leaves the fucking barrel, there is no excess pressure past what the gun is already designed to handle in normal operation.
the gas system uses some of that pressure to cycle the action, and the gun is designed to operate with the gas system intact. blocking the gas system can and will cause a catastrophic failure
stop posting
>>28881063
>go block your gas system and fire it, let me know how that goes for you.
i do that, nothing happens.
>>28881106
no, it won't.
as long as the gasses can go back out the barrel, there will be no catastrophic failure.
>>28881133
please take your retardation somewhere else
>>28881105
>into a tube full of lube
nah, the problem was too much gas, moving too fast, and going into a chamber that moved just enough to let more gas in but then didn't move anymore so the pressure built up massively and the carrier went boom.
if the gas had time to equalize then the gas tube would pop, but it didn't, so it didn't.
>>28879579
>AR fags will defend this
>>28881153
If that were true the bolt would not still be in place.
>>28881143
>hurr i am wrong but i will just call him a tard
>that makes me right
look, i can block off the gas on my suppressed(so i have oodles of extra gas) ar at the receiver and it doesn't blow up, it just doesn't cycle.
>>28881153
do you realize your arguments keep contradicting yourself?
>>28881164
people are calling you a tard because you're saying retarded shit
>>28881159
the bolt it bulged/broken and stuck in place. look at the crack in op's pic, if the bolt hadn't been damaged then all that might have happened is a sheared lug or three.
>>28881166
how so, friend?
if the muzzle is clear then the blocked tube will just send the gas out the barrel.
if the muzzle is blocked and the tube is blocked at the receiver, then the tube will burst.
>>28881174
explain how i can block the gas at the receiver and my gas tube doesn't pop?
>>28880951
>>28881008
>>28881049 and >>28881091 are right about the gas tube, as long as the projectile is leaving the barrel you could quite literally weld the gas tube closed or insert a dowel in the receiver extension preventing the carrier from unlocking and moving rearwards.
A soon as there is is a blockage in the barrel only then do you run into an overpressure situation. In the unblocked barrel but blocked tube or dowel situation the gas system reaches the same pressure within the barrel then stops pressurizing as the bore pressure only continues to drop as the projectile moves further down the barrel past the gas port. It is designed to work under these pressures, nothing out of the ordinary.
A 16" barrel where the bullet clears the bore only has ~7,500psi of muzzle pressure and a carbine gas system is at 7.5" which is still only ~16,500psi whereas at the case mouth 5.56 chamber pressure is ~54,000psi once again assuming the projectile travels down and out the barrel normally.
I don't know the math behind the maximum volume of expansion of a standard load vs the volume of a blocked/capped 16" barrel, but you can expect that Colt 6920 which is going to be based off of a hoop stress safety factor of at least 2 for the 4150CMV it is made out of as they are military profiles is far stouter than the much weaker metal 8620 carrier or 7075 receiver. As soon as you stop the projectile from exiting the barrel, that is where you encounter your overpressure in the gas system but it wouldn't be catastrophic yet as long as the bolt is able to unlock and relieve pressure.
The assumption for this case is both the barrel and the recoil system are blocked. At that point the barrel and gas system become one giant pressure vessel and the gas/recoil system will let go long before the barrel.
>>28881207
>The assumption for this case is both the barrel and the recoil system are blocked.
this, i assume the bolt couldn't rotate because it's is stuck in the barrel and the barrel extension is cracked. the only thing that i could think of that could cause the barrel extension to crack is a hot round or a bad head space.
>>28881207
Thank you for doing the math I was looking up
This discussion has given me an idea though. A "safety" system for Brits and those stuck with straight pull ARs with no gas system. Basically a blocked gas tube that will rupture in a safe direction in the event of a squib. Then, if one were so inclined, a few minutes with a drill and an actual gas tube could reinstate semi-auto function.
>>28881268
that would be easy to do, the hardest part will be making the gas tube that will burst just after safe pressure and with enough volume to release enough gas so the barrel doesn't explode.
you would also have to place the port as close to the chamber as possible so there is less of a chance of the blockage happening before the port.
>>28881254
This is indeed an interesting one since most catastrophic failures of the receiver are either out of battery, or an extreme overpressure at the chamber where the case head lets go and detonates the bolt head.
I'm curious if it can be deduced that that bolt was locked in the fractured extension and then fired or if it fractured during the failure and the bolt did not unlock due to another reason.
you guys are retarded. Blocked gas system will not blow up, it just wont cycle a new round.
Blocked gas = bolt action. you would just have to manually charge a new round.

>>28881420

it's possible that the extension was broken before but my guess is it all happened on the same round.
i doubt we will ever find out but it's fun to think about.
In my expertise.
I point all finger and suspicion to something that cause carrier to experienced waay more pressure than normal.
One real answer is weak primer flattened/collapsed and fail as internal explosion gas blow through primer hold and into firing pin hold and filled carrier with pressure only seen in chamber area. The exploding gas also went around the bolt and subjected extension to pressure it was never made to handle a explosion instead of just back thrust force of bolt lug against extension lug.
Tripfag internet reputation
1+.
Also i have seen giddyfuck/GODOFMAUR's guess >>28880876
But hahaha my primer failure diagnosis is much more likely and realistic.
Primer failure is common because of usage of wrong weaker primer for high pressure rifle caliber or simply overpressure round that primer was never made to handle.
Go google flatten primer. Thats what happen before it fail. Flatten primer is pushing the limit.

besides, if the gas was going through the primer, it would shove the bolt into the carrier.

>>28881106
for fuck's sake, have you not heard of adjustable gas blocks?
you can turn the gas down all the way on FAL, it just won't cycle. It doesn't blow up in your face, dumbass

>>28883413
To be fair, he was thinking the gas tube couldn't handle the pressure and would burst. An adjustable gas block would cut off the pressure ahead of the tube. He's still a moron though.

>>28880371
if it was overcharge how is the bolt still chambered in the barrel, and the barrel wasnt split open? it was only the upper receiver and back of the bcg
>>28883340
Wrong. Thats only if cam failed.
>>28885149
or if the lugs shear
>>28885173
No. If all lug sheared the cam would still be there. The bolt will still be as much in the carrier it was already.
>>28885097
Because the AR vents gas into the BCG behind the bolt to operate. So the right kind of failure can lock the bolt into the barrel extension.
Odds are this was a squib and then a hot load, with maybe a side order of excess headspace. The squib helped generate the overpressure scenario, the hot load stretched the case, forcing the locking lugs to bear on the mating surfaces of the barrel extension, cracking them but also resisting bolt rotation. The excess pressure (perhaps exasperated by fluid lock due to excess lube) hammers into the bolt carrier, but instead of caming the bolt through its rotation and then carrying the bolt rearward, the carrier splits, leaving the bolt in battery, and breaks the receiver.
So what we have here is a shooter that thought squib was a miss and that his rifle needed a relube because it didn't fully cycle, who then poured his bolt carrier full of lube and tried again.
Kaboom.
Just proves that ARs are nothing more than tacticool shit.

If the tube was full of oil, it would have worked fine at the start. But as more and more carbon and stuff blow though, they would stick to the oil in it.

If that were the case, and your analogy is piss poor, then the only thing that would split would be the gas tube (aneurysm). This wouldn't cause the brain to explode a la Scanners.
