Well, both civilian cartridge and rifle have need a full development cycle. SiG decided to develop them independently of final NGSW winner, because they could not it a number of months ago

Havent seen this one before , would be surprised if the plastic case needed to be from 3 parts 

The CT-style full loop belt grooves (allows the use of polymer links), on the TV-style case warrants serious investigation as a possibility for True Velocity, I wonder if they're aware of the concept to begin with 

Why is the right cartridge labeled "6mm ARC" when the bullet is of the same diameter as that of the 5.56mm Mk262?

Using full-loop polymer links does not seem feasible for machine guns that shoot TV ammo.

I guess the Photoshop operator had no idea that Mk262 has a smaller bullet diameter. For purely aesthetic reasons, he chose to give all bullets the same diameter. Clueless marketing people did not see any mistake. Engineers/technicians were of course not in the loop.

Well, the "photoshop operator" is probably the one that gives us the superb 3D mechanical rendering of the Textron NGSW weapon (among other things), so I think that this guy knows what he was doing.

EDIT: I think he is even on this forum.

It was posted on Twitter.  No info on who drew it or why.

Who do you guys think is gonna win the ngsw? 

That cartridge isn't even remotely like 6mm ARC, which is fatter than 5.56 and has a much shorter case.
