I love these meltdown videos, really shows that pretty much any gun is going to be so hot it is unusable without special protective equipment in normal conditions before the gun itself fails.
I do wonder how much the air temp would affect this as well, how many more mags on a -10 degree day vs a 90 degree day. |

It went the farthest so far of the ak and other M16 versions. . It truly was impressive. Even at the end it still functioned in semi auto . Im guessing something worked out of spec causing the malfuntions.It didnt melt the has tube like a di rifle does .You would still be viable in a fire fight. Ive seen videos of 50 cal gunners have to cycle the bolt more

What is the service interval on this particular gun? After 500 rds? 1000?
2000 rounds back to back to back without a service break is pretty damn impressive. |

Before the receiver got really hot you could see the front end of the bolt was really hot in the thermal. It's easy to see when the bolt lock back see around the 4:47 mark.
I thought the claim to fame of the 416 piston uppers was the bolt never got hot? |

After the end of the test I would have liked to see them let the gun cool, clean and lube, then see if it'll fire three mags or so.

Impressive for sure, but I don't know you can call that a continuous 2500 rounds due to the stop in the middle for the stuck case, and the 2 and 3 round bursts that were happening before that.
Seems like the gun got hot enough to short stroke IMO. Maybe expansion of the piston in the gas block or something? That would explain the lack of holding open, and the FTFs. Still a fun video. |

I'm betting if they were shooting xm193 it would have fared better.
How many rounds did the budget ar get through before the gas tube exploded barrel exploded? https://www.youtube.com/watch?v=BSizVpfqFtw I'm betting that an ar with the POF barrel style and heat dissapator will go just as far. |

He hadn't fired 2,500 rounds at the 4:00 mark. Also when Colt did their torture test of the M4A1 it went to around 970 rounds in full auto with no stoppages until the gas tube blew out and then it functioned as a single shot. This was with a double insulated heat shield handguard so it may have gone longer with a better vented and cooled handguard like the KAC RIS. I would be interested to see how that old Colt triple thick gas tube would hold up....The one they used to use on the M16 built as a IAR. |

I'm betting the problems started when the gas port area got hot enough for the gas port to erode at a rapid rate. Premature unlocking while the steel case walls were still pressing against the chamber, which then decelerated the BCG to the point of short stroking. The short stroking was not giving the magazine enough time to position the next round for feeding. This was exasperated by full auto fire not giving the magazine enough recovery time between feeding cycles. Semiautomatic fire gave the magazine time to recover and be able to feed the next round despite the premature extraction induced short stroking. The premature unlocking is what caused the cases stuck in the chamber with the rims ripped off by the extractor.
I'm curious as to whether using brass cased ammunition would have had a significant effect on when stoppages occurred. |

IMO brass cased, 5.56 pressure ammo would have worked better for two reasons, better seal at the case mouth, so less carbon in the action, and hotter ammo to work the dirty action with more energy.
Not sure how much better it would have worked but it should made some difference. |
