The 6.8X43MM SPC II cartridge was developed as a part of the Enhanced Rifle Cartridge Program to address the deficiencies in terminal performance seen with 5.56x45mm NATO cartridge while allowing the soldier to carry the same number of rounds with a minimal weight penalty. By using a heavier projectile, the 6.8 round offers more impact energy than the 5.56 NATO round across all effective ranges, effectively bridging the gap in lethality between 5.56 NATO and 7.62 NATO. A major drawback of using the 6.8 Cartridge in an M4 style weapon has been the lack of reliable magazines. To solve this issue, LWRC designed the SIX8 family of weapons around the magazine. Through a partnership with Magpul, the leader in polymer magazine engineering, LWRC designed the first polymer 6.8 magazine. The SIX8 PMAG features many of the same design characteristics of the standard PMAG, including the curved shape and familiar texture.

Based on the old 30 Remington case, the 6.8mm SPC (6.8mm Remington Special Purpose Cartridge) was developed in conjunction with Special Operations Command (SOCOM) and introduced by Remington in 2003 as a harder-hitting alternative to the 5.56X45mm NATO cartridge. Bullet diameter is .277-inch, same as the 270 Winchester, but the cartridge was developed to fit into the AR platform by switching out upper receivers, so shorter (lighter) bullets must be used. Standard is a 115-grain bullet at 2625 fps. Although the 6.8mm SPC has seen combat use in Southwest Asia with good results its wholesale adoption by the military seems unlikely. It has, however, found favor as a hunting cartridge in the AR platform; its many fans consider it an excellent deer cartridge out to perhaps 200 yards. — Craig Boddington
