From Iraqveteran8888, “In this video we attempt to burn out an AR-15 upper on an M16 lower. We are testing the durability of not only the upper receiver assemby but few specific products as well including the SRC Relia-Bolt BCG, Geissele Super Gas Block, and one of the most affordable AR barrels on the market from Faxon Firearms.”

When I test just about any firearm in my snail trap after repair I wear a face shield and build up layers of clothing. My helper pulls the trigger with a rod while I wear leather welding gloves.
It was said that it was steel cased ammo, but was it steel jacketed(bi-metalic) bullets as well, like most Russian steel ammo??
That’s why I love my AK’s.
That would never have happened.
But then again you proved that in your previous video; “In Memory Of Kalashnikov: 700 Round AK Burn” https://www.youtube.com/watch?v=lND51FkLuFU&feature=player_detailpage
Just for fun, here’s a torture test video of an all American built AK shooting 1000 rounds!

I am impressed. Not simply because they spent so much money destroying this rifle, but it shows how good it really is. In particular I like how the DI system held up so well. Except for the wearing of gas rings on other rifles, the only bolt I found with gas cutting in the tail was in a $3000 AR10/25 with 100 rounds fired. Had that particular 7.62mm bolt been made with the proper heat treat and materials it would not have failed. This company did a good job making that bolt.
I would wear much more protective clothing and face cover if I were you.
So that is what passes for eye protection when you intentionally run a gun to failure?
Not with my eyes!
It failed in my opinion when the failed to feed happened
Would be cool to see this test performed with an AK. Also, since the rifling was eroding away, could it have been a chunk of rifling peeled up that caused a blockage in the barrel for the next round? Would be interesting to see if a high quality match grade type barrel would fair the same fate.
See my comment below Phil
amazing…………you couldn’t see it but from the side view the barrel was going crimson as you got 500-600 rounds into the test toward the end of a mag. Steel gets soft when you push it that hard.
I’ve seen M-60 barrels get so hot they were almost white and you could swear you could see the round through the steel leaving the barrel. Or course that barrel is stelite (exhaust valve steel) and made for some abuse (but not THAT much abuse).
We were giving her “the whole 9 yards” and the barrel was shot out anyway…………
I would have thought the gas tube would blow out, not the barrel. Well made bolt and gas assembly.
You might want to stake those flash hiders onto those barrels like the bolts on the gas key.
Great stuff.
Wonder how a heavy barrel would do?
OK I give up why do tests onthings that will never occur in real life
You never heard of the impending zombie apocalypse eric?
It certainly shows that even under such abuse, the M16-type DI rifles work well. The only failures I personally had were all related to ammo, especially commercial reloads.
You could see the barrel glowing towards the end of the later burst. His magazine changes while fairly fast, at times towards the end allowed quite a bit of cooling. I’m retired(1994) from the Ballistics Research Lab.(BRL) at Aberdeen Proving Ground, Md. and ran a small arms range. I didn’t run any M16’s to failure but watched them do it at other ranges and they did it from a hard rest. Two gunners allowed them to make mag. changes rather faster. They could therefore heat a barrel to failure quicker. It was known how many rounds would blow a barrel so they could avoid it when doing for instance a magazine quality test. They would test magazines to qualify manufacturers and would fire millions of rounds doing so. Knowing the limits of the barrels would prevent this…. BTW, the gunners would duck behind shields and fire with a string. Such testing took MANY rifles and many days. Guns were rebuilt and rebarreled at night by many gunsmiths. Not that much fun. Just work. I recall going home with cut fingers from loading magazines all day after even less extreme testing. IMO the AR/M16 is and has been a great weapon.
With due respect

How many rounds was that?
I think he said 830 rds, late in the video. Impressive. He should have worn better eye protection, perhaps a full face shield. It is interesting how the gun functioned under such abuse.
That was a wild ride! Definitely a lot of abuse on the system. A fwd pistol grip could give you a bit more distance from th epicenter. You realize you need to do the same “test” with a full auto AK. You may want to add how the barrel was made. Any idea if it just blew from heat and pressure or was there significant errosion in the blown area combined with the start of barrel taper? Is the edge of the blowout thin or thick? A split/crack blown open or exploded with material missing? Great vid. Thanks
Stainless barrels are weaker than chromemolly, hence the failure before the the other parts.
