I see that I'll have to do a "reverse" weight reduction plan to show how stupid this all is.

Usually, LMG=belt-fed and/or quick-change barrel; AR= mag-fed and "fixed" barrel. That's my personal rough and dirty definitions. YMMV.

I quite like the aesthetics of a bullpup rifle, so that’s not a negative for me.

Ditto.  Personally, I love the bullpup concept.  I'm just skeptical that the US Army will go for it.

Someone would have to remind me on the difference between a Light Machine Gun and an Automatic Rifle...

I'm not sure if there is a consensus.  When talking about modern weapons, I see it basically the same as Farmplinker:

LMG = belt-fed

AR = mag-fed

RovingPedant said:

I’ve never been convinced that LOP is an issue for flat-topped rifles with long sight rails.

I don't know if it actually would be a problem or not.  But it looks like it could be, depending on the optic used.

General Dynamics Ordnance and Tactical Systems RM-277 - Maryland ...

Assumptions are 140 rounds per gun for all the NGSW rifles, 1,000 rounds per gun for the NGSW belt feds, and 220 rounds per gun for the GDOTS mag-fed AR.

You posted the reduced load elsewhere but I can't remember it - memory isn't what it once was...

So is it accurate that most of the weight savings for the GDOTS combo comes from a sharply reduced ammo load for the AR/LMG?  

How are the Marines loading up their AR gunners with the M27?  Just a 30% increase like you're calculating for the GDOTS AR?

Yes. I have them carrying 1,420 rounds per squad, instead of 2,980 rounds for the other two.

Correct. 11 magazines (330 rounds for the M27, 220 rounds for the GDOTS NGSW-AR).

GIGO.  Your assumed ammo loads may be quite different from the actual ammo loads.
