I was pretty impressed by the barrel being stainless steel. That's for sure. That said getting into metallurgy and all that is a whole different ball of wax. Different products are meant for different things and full auto is really a speciality thing if you ask me, the hardness, the heat, how the metal expands, and at what temperature, etc etc. I've tried to burn the barrel off of an MP5... we had that thing just SMOKING but not all barrels need to be able to stand up to that kind of abuse. I don't know what kind of metals are in an HK but it ain't stainless steel :)

That was fun. Would have liked to have had a second camera for closer slo-mo view of the "red zone."
I once watched a malfunctioning M-60 run through a 100 rd belt. All the prone shooter could do was hang on. The barrel turned bright cherry but held up.

I'm honestly surprised they didn't use a milspec chrome lined barrel like in the original test they emulated

At 8:18 the gas tube fails and V7's Inconel tube has a much higher heat failure threshold.

Your right. His initial statement at 8:18 was "The gas tubes done" But then after further inspection and editing I suppose, said it was a barrel failure. I was fast forwarding and rewinding so much I missed that part. My bad...

Anyone who has seen a video like this expected a gas tube failure, it looked like several times it was close to rupturing.
