A gun failure test is designed to see what it takes to stop a firearm's operation. This test was conducted by firing an AR on full auto going through several magazines, before the unexpected thing happened.
The gun didn't stop firing, but it did burst into flames. The test itself appeared to involve shooting the gun as fast as possible until it quit firing. Well, that didn't happen. Watch the video to see if you think this gun passed or failed.
Maybe that’s why they always tell you to shoot in short bursts. LOL!

Either way, the gas tube will get glowing red hot during extended mag dumps, and that can easily set plastic forearm parts on fire.
Expensive test. ;)
That’s what happens when you cook bacon on the barrel.
Just took mine to the range Tuesday, put about 50 or 60 rounds through it in maybe 20-30 minutes (zeroing my red dot). barrel was so hot I let it sit for 15 minutes before I put in back in the case.
Tap, rack bang would not work in this situation, said Capt Obvious.
Agree, to the fact that it was the handguard that caught fire. Definitely a poor handguard design. I’ve destroyed a couple of barrels on a M249 on purpose, but have never set the handguards on fire.
There are several guys with “burning brand X” rifle vids online. mostly it is done on purpose.
My Grand Father managed to get his M1 Garand to smolder while teaching street fighting in N.Afirca before invasion of Italy
He poored water on it and then went back to shooting.. The M1 was (and is) stout!
You can burn holes in the gas tubes too. That slows the rate of fire down quite a bit.
The AR has a small gas tube that runs from the sight block back into the receiver, and it will glow red from prolonged firing, and will often burst once it gets hot enough.
Those things need to be water cooled. Someday we will see water bags hanging on the backs of shooter as they plug in the AR to the water cool connecting ports. Perhaps they are already so equipped.
Yes, I’m aware. I’ve done sustained fire from an M16A4 and a M4A1 as well having never melted the barrels or cause the weapon to catch fire. I mentioned the M249 as I have damaged the barrels on that weapon due to a sustained rate of fire.
I guess if that’s the way one wants to spend their money.
Personally I find money hard to come by and I don’t try and abuse any of my equipment.
Lube fire
Also called Nube fire after newbies who don’t know enough to wipe off excess lube oil.
That could "catch" on around here :)
Kewel!
