Sig 6.8 ngsw

[LRRPF52]

The Machine Gun weighs in at 11.97 lbs, while the Carbine is 8.1 lbs with no Optic or Suppressor.

So a larger-than AR10, piston-operated carbine, chambered in what amounts to .270 WSM at 8.1lbs empty.

Add on LAM, White Light, LPVO or RDS, and the beast suppressor that will be required to take the beating of insane muzzle exit pressure with a 13" barrel and you have a recipe for a monstrous abortion. Gas port erosion is going to be a witch on that one, unless they use that unobtanium barrel alloy they've been developing.

Bulk volumetric displacement of the ammunition and magazines will be in excess of 7.62 NATO. Good luck with that and the soldier's load.
