I think it's beyond time to shut this one down.

As Hillary would say, the science is settled?

ETA: I've read it all, I have learned things I did not know, just like most discussion on this forum.

Same here, you just need to know which lines to read between.

I think the issue is that a "di ar", everyone knows what that means, to differentiate it from a "piston" ar even though it technically has a piston.

What it is does not equal what it has, as people use the terms.

There are manually loading and self loading pistols and rifles.
The way they do it is different among them.
The AR is a gas operated self loading rifle; period.
We all know how it works and works very well I may add.
After reading all this I have to ask; why ?

Well, my wife got involved. She read three posts and decided piston. I've been calling it DI forever. The big question is, how will we raise the kids?

It has been interesting, I'm satisfied that academically I should think of the AR as a piston system, but at the end of the day, does it matter?

We all know the Stoner design works and works well. It has commonly been referred to as DI for as long as I've been reading on it. As long as we all know what we are talking about, as in when I refer to a DI weapon vs. a piston AR, the purist may snort in derision, but they know what I'm saying.

Let it go. It's like arguing whether Jesus went potty or not.

ETA: Highlight of thread: Fail 2 Stop to Hans: Dude... Just seemed, well, pretty funny.

I've changed my mind....rather than DI or Piston, I'm calling it "Legacy system AR" and "Piston system AR".

No confusion. Nothing to argue over.

If that is true then you must demonstrate how any gas operated firearm is NOT piston operated. How is an agm42 not piston operated?

Well, if you drop the numbers for a Hakim into this model, you get some pretty reasonable results. (I used a Hakim as I don't have a P-T curve for 6.5 Swedish.) It behaves like a piston system.
