This is an extreme test. When dirt gets into the chamber every gun is going to fail...
The AR pattern rifles are very well sealed IF they have the port cover closed. That is not always the case.

There's a ton of mud sitting on that bolt right before he shoots it with the dust cover down. Considerably more than you see on the Stoner pattern tests.

It seems relevant, at least in the above-linked previous demonstration with an AR, that he finger-swiped the majority of debris clear with "let me get the rocks out of the gun" and then swipes 4 times in 2 different direction.
As opposed to: https://youtu.be/HYAEGgf_8LU?t=187 wherein there is no finger swipe and a minimal shake.
There are many, many advantages to short-stroke gas piston ARs of quality: and most of them are primarily relevant to organizations and less relevant to individuals. Reduced wear to the operating group, extended barrel life, reduced backpressure when suppressed, and a greater tolerance for shorter barrels and excitable shooting are examples of such. These are in turn counter-balanced by such minutiae as increased weight, altered recoil impulse and\or peak-stacking on the accelerometer, cam-pin gouging, bolt carrier tilt, and the cyclic rate increasing to the point of sync-issues with the ability of the magazine spring to feed in-pace with; the sort of thing that orgs don't mind finessing, for what they take in trade.
The HK 416s have done well for themselves in a range of configurations and places.
The LWRCis.... less so. One Fed LEA in particular has had a pretty broad range of issues with them.

Please, hurry.
The gas system is much different on the 416. IT's a well known quantity and it goes through a very aggressive torture test vs the MR556. Which is a much softer recoiling/less aggressive gas system.
A lot of people purchase ported gas blocks for their 416 uppers to reduce the aggressive recoil. Which reduces the accuracy, but it powerhouses through almost anything you can throw at it. Now that's not to say there aren't conditions that will shut it down, or a gun is completely immune to failure. But the differences between the 416 and MR556 are huge.
Accuracy is important.
Our team ran 416s for a bit...we had issues running them suppressed. Everything mechanical is fallible.
What can were you running and what kind of problems?
You should've posted the P30 having an epic failure. It would've been more entertaining.
