Not really, the gas system was terribly designed. Piston AR's run much cooler and cleaner.
It's really an inferior design to the AK or M1A.
It improved with the addition of the forward assist and dust cover but wasn't perfected until the gas system was replaced with a piston drive .

It's apparent some aren't familiar with the fact that the Stoner system (both ar10 and 15) are indeed piston systems. Instead of a heavy and harmonic inducing op rod, the bolt itself inside of the bcg IS the piston.
Note Stoner patented the system as piston driven, not DI.

The AR's/M16's as originally tested and eventually given to the US military were direct impingement, not gas piston driven.
The example in the OP is DI, not GP driven.
The example in your video is not either.
The gases are recirculated back into the upper via a gas tube that empties them into the BCG and upper.
This causes rapid heat buildup and excessive fouling.
This is an actual piston driven AR.
Review: Sig Sauer Model 516 Gen 2 Piston-Driven AR - AllOutdoor.com
The heat and fouling don't make it into the BCG or upper like they do with the original system allowing them to run far cooler and cleaner.
Actual piston driven AR's are the future, not the original Stoner system who's only advantages were weight and cost of manufacturing.

Love the video! I knew nothing about the internals of an AR. I had heard generalities about the DI/Piston versions, but never got into the particulars.
In my youth I worked in a machine shop, and I love to know machines down to the tiny details.

It is a principal object of this invention to utilize the basic parts of an automatic rifle mechanism such as the bolt and bolt carrier to perform a double function. This double function consists of the bolts primary function to lock the breach against the pressure of firing, and secondarily, to act as a stationary piston to actuate the automatic rifle mechanism. The primary function of the bolt carrier is to lock and unlock the bolt by rotating it and to carry it back and forth in the receiver. The secondary function of the bolt carrier is to act as a movable cylinder to actuate the automatic rifle mechanism. By having the bolt carrier act as a movable cylinder and the bolt act as a stationary piston, the need for a conventional gas cylinder, piston and actuating rod assembly is eliminated.
It is an object of this invention to provide a gas system which is lighter and less expensive to produce because of its simplicity than the present gas systems now used in automatic rifle mechanisms.
It is another object of this invention to utilize the energy of the expanding gas developed by the firing of the weapon, for actuating the automatic rifle mechanism directly by use of a metered amount of the gas coming from the barrel. This invention is a true expanding gas system instead of the conventional impinging gas system. By utilization of a metered amount of gas from the barrel, the automatic rifle mechanism is less sensitive to different firing pressures caused by variations in the propelling charge. It is therefore still another object of this invention, to provide a rifle mechanism which is not affected by variations in the propelling charge.

Stoners patent circa 1956.
During the war he designed aircraft and after designed aircraft weapons systems.

Look you two, you are talking at crossed purposes.
The design is absolutely brilliant in the abstract.
However, that does not make it practical or reliable in a service rifle in a jungle mudfest or various sandbox environments where cleaning intervals vary wildly.
The one thing about a piston design is that is helps keep the action clean. Cleaner action more chance rifle goes bang!
I do see the beauty of what Stoner tried to do, get the gas to do two mechanical tasks AND reduce weight and price dramatically. Look at the Ruger AR-556 vs the SR-556.
Thetruthaboutguns had a review of the AR556 and said this:
"What’s the difference between Ruger’s AR-556 and their SR-556? About 1.5 pounds and $1246.00."
I am not suggesting that you agree to disagree, I am saying that you are not talking about the same topic.
