The 6.8 mm Remington SPC (AKAs: 6.8 SPC, 6.8 SPC II & 6.8x43 mm) is a rifle cartridge that was developed by Remington Arms with collaboration from individual members of the U.S. Army Marksmanship Unit, United States Special Operations Command to possibly replace the 5.56 NATO cartridge in a Short Barreled Rifle (SBR) / Carbine.
Based upon the .30 Remington cartridge, it is midway between the 5.56x45mm NATO and 7.62x51 mm NATO in bore diameter and velocity. It uses a .277 (7.036 mm) diameter bullet, which is the same diameter bullet as the venerable hunting cartridge .270 Winchester uses. It is particularly adaptable to current 5.56 mm NATO firearms, the cartridge overall length being comparable.
