Aren't the problems associated with excessive chamber heat in DI ARs caused mainly by people using an AR like an LMG instead of a rifle?

That's the point of the IAR.
Feels like an M4, puts out a lot more lead.
Lots of ways to contribute to the success of that application, but weight reduction is not one of those.
I have shot M4s to the point that they had cook-offs.
6 mags in less than 5 minutes will get you there.
Drop that to 4 mags in the same time and you will be ok (non-SOCOM thickness barrel).
IARs will push more, and the op system helps, but it isn't the only factor.
There is also a change in application. The IAR is not an LMG, its an Automatic Rifle, and it has to be shot as such.
Gotcha. Thanks for the explanation.
Or perhaps we are in for an era of well trained and qualified individuals who know when and how to properly use full auto fire..."Perhaps we're in for a new era of spray and pray, with awesome new hardware that can keep up?"
IIRC, "spray and pray" was the standard approach when the Army adopted the M16 back in the 60's, the philosophy being that if you put enough fire downrange, you're bound to hit something eventually.
