As any other recent SiG design, the back of the receiver protudes far from the grip. Return spring are quite different than in an AR-15 design and it doesn't need buffer. Stocks can be foldable

Yes, the feed device is unusual.

It appears to be an open top box, similar to a regular LMG ammo box.

But, it appears to have a vertical "feed tower" in order for it to be inserted into a mag well on the LMG. If that's the case, I suspect the ammo boxes are going to be unnecessary bulky in pouches, due to the need to accommodate the ~2" vertical feed tower. Similar to the problem with storing AR compatible drum mags.

And I agree, the size looks small.

It will be interesting to see more about it, that's for sure.

Perhaps I'm missing something.  How does the shape of the back of the receiver make it look like a DMR?

I think they're doing something interesting with that belt box.  Note that it's covered in fabric material.  I suspect it is intended to be attached to a load-bearing vest using the same post interface that holds the box to the gun.  That means there is no pouch to shove the box into; the shooter just pulls a new box off the vest and slaps it onto the gun.

I think you're mistaken.  The top photo in post #19 shows what appear to be mag pouches for both the LMG and rifle.

The use of fabric for construction of the belt container just follows the current practice with the M249 and other LMGs.

Perhaps.  We would need to see what the feed device looks like by itself.  If it does have a bulky tower, that could be problematical, since it appears to be a belt-fed-only weapon, unable to use box magazines.

Those are great pics Stan. Is there another release of pics from Sig?

"Indeed SiG's carbine entry looks like a short barrel marksman rifle more than an assault rifle. A weapon intended for careful and precise shooting."

Sort of.

The SIG NGSW appears to be a modified version of the SIG MCX-MR, a 7.62x51 version of the Sig MCX that was developed for the CSASS competition.

MCX-MR 7.62 vs MCX 5.56:

So indeed, the rifles origin is as a DMR. 

But as their NGSW submission has a 13" barrel, and the goal of the NGSW is a M4 replacement, I imagine that while its probably impractically powerful and recoiling to be a Assault Rifle, that is what they are submitting it as.

It would seem so.  The pics are from this article:  https://www.gunsamerica.com/digest/sig-sauer-army-ngsw-machine-gun-rifle-contract/

To pick a nit, it's being submitted as a Rifle, not an "Assault Rifle".
