M&P Meltdown video

[SupportTheSecond]

Yes it is a couple of years old so I am unsure if it was posted before, but being a relatively new owner of the latest model I found it and the comments interesting. I apologize if it was posted before I didn't see it here.

Those sorts of videos are tantamount to testing cars by over reving them and pushing them off of cliffs.

I would say it is more like taking the car out on the track and abusing it until something broke. Which companies actually do since it can expose areas for improvement.

I have to agree with Oldsalt66. While the video is entertaining, it really doesn't provide much information. First off, they had to use a different BCG. So right off the bat, they changed out the heart of the rifle, and so it is no longer a test of a S&W Sport II. Second, it showed firing to a point of failure, but when did accuracy begin to suffer? All I learned is that the gas ports eroded before the gas tube failed on that particular sample that he was firing.

It still says a lot for the melonite coated barrel.

Fun to watch but it doesn't pertain to my Sport 2. As I have a strong feeling I won’t have 820 rounds on the range table at one time LOL……. Let alone using machine gun parts.

But being new to AR’s I am impressed in how well it held up.

What does it say? I would have expected the gas tube to rupture before the gas ports were eroded to the point that the rifle wouldn't function. And like I said earlier, at what point did the accuracy drop off?

I like to watch these videos and am entertained by them, but I'm not sure they really prove anything.

Unless you are really insistent on using corrosive ammo, melonite is better than chrome lined.

Better for what?

Accuracy? Technically melonite should be better, but most won't see a difference especially with green tip and similar bulk ammo.

Melonite is said to be better for corrosion control as well.

For melt down videos, the chrome lined should last longer if all other things are equal.

Point is, which one is "better" is going to depend upon the application. Same argument as 4140 vs 4150 barrel steel.

Not trying to bash the Sport, I have a first generation Sport and love the rifle. It does everything that I need an AR to do.

I'm sure these tests are fun to do, but there's really no science behind them. This is just a guy who's not good a making videos trying to get more views so he can make more money.

There was no hypothesis.
No control.
No baseline set.
No measurable methodology or results.

All this shows is that this guy can shoot a gun until it fails. His comment, "Man, that's really impressive!" has no basis on anything he did.

Now, take a regular Sport II and shoot it until the groups open up. Shoot it as intended as a semi-auto to see how the trigger group holds up. This is the kind of testing I'd like to see.

My own professional experience in designing procedures for properly testing complex mechanical systems to destruction says otherwise.

FWIW, that S&W rifle upper was for all intents and purposes destroyed by the high temperatures it was subjected to far before it actually stopped running.

The barrel was warped, the heat treatment was destroyed rendering continued firing unsafe, and the rifling was shot out of the softened metal way before the thing could no longer fire.

And heck, he didn’t even run the entire rifle at all.

He provided nothing of any true value other than some entertainment.

That wasn't the experience of the USAMTU in rapid fire match use per the then commanding officer. (Prior to 2015)

 

[MTC(SS)Ret]

Do ya think he would try something like that now when 5.56 is a buck a round?

 

[S&WIowegan]

I wonder who or how he gets the money to do "stuff" like that???

 

[rockquarry]

Maybe I'm missing something here, but is there a point to a "meltdown" video? It takes little talent to destroy something. It would seem that most people have better ways to spend time than to abuse or watch someone abuse a gun or anything else. Again, I may be missing a key element of this project.

Mr Browning sat down behind his 1917 and held the trigger down for 48 minutes. He said he would have like to have shot for an hour but that was all the ammo they had (21000 rounds).

It’s a “meltdown” test not a 1000 round range review. The whole point is to push the rifle to the most extreme point possible and see what holds up better and what fails earlier, and mostly on the upper.

The lower reciever, fire control group, and bolt carrier group were not involved in that ridiculous video at all.

All he did was install the upper, sans BCG, onto a full auto lower and fire rounds through a barrel and gas tube that aren't designed for full auto, until they were destroyed, which happened way before the external signs were obvious and firing ceased.

How about we "test" the suspension on your vehicle by installing it on a Mack Truck and then ejecting it from a cargo plane at 20,000 feet?

Or test the engine by running it without lubricant or coolant?

That video "tested" nothing, the barrel was warped and the rifling was gone, as was the head spacing, way before it warped to the point that it could no longer fire, and the majority of the rifle wasn't even involved.

Entertaining, but fairly pointless IMO.
Would not be conditions that would have any bearing for me...or really anyone not seeking clicks on YT.
