They aren’t talking about 6.8 SPC, they are talking about 6.8 Magical Unicorn - the Army’s NGSW cartridge that is going to produce .270 WinMag ballistics from a 16” barrel while having a 10,000 round barrel life with no appreciable loss in accuracy and a faster sustaimed fire rate than an M4.

There was also a 6.5 Magical Unicorn cartridge that appeared here and there but it seems the moderate increase in bore size makes for a significant difference in barrel life.
