HK416 standard rifle (not IAR)
The H&K entry was a modified version of their HK416 piston-operated AR-15 rifle. Unlike the Colt and FN entries, it is said to fire only from a closed bolt. Given the lack of an open-bolt fire mode I had presumed it was the least likely choice for an automatic rifle.
Presumably it is fitted with a heavy barrel, like H&K's previous, and commercially unsuccessful, attempt at the automatic rifle: the MG36. The Marine Corps has been reporting the weight of the 16.5" barreled H&K IAR as being 7.9 lbs. This is not possible as a standard 16.5" barreled Hk416 weights in at 7.84 lbs. I also think that the photo of the H&K IAR shown by the Military Times is that of a standard HK416.

I have contacted H&K to see if they are willing to publicly acknowledge if they have won. If they do, I will endeavor to get the specs of the new weapon.
