The Marine Corps Times is reporting that General James Mattis pushed for the adoption of the 6.8 SPC as recently as this past December. The increased stopping power of the 6.8 SPC as compared to the current 5.56 was a significant reason behind Mattis’ efforts.
The 6.8 is a cartridge that fits into the AR-15/M-16 design envelope, but uses a larger diameter (6.8 vs. 5.56mm) bullet, that generates more energy. The idea is Marines would be able to use the same weapon platform with a chambered in a cartridge designed to be more effective at stopping the enemy.
Instead of the 6.8 SPC, the Marines recently adopted the 5.56mm Special Operations Science and Technology (SOST) cartridge, which promises to be more effective at stopping the enemy and defeating light, intermediate barriers.
