The Barrett M468 was a variant of the M4 Carbine rechambered for a heavier and larger 6.8mm bullet for increased terminal performance. The designation of M468 stands for an M4 carbine chambered for the 6.8mm SPC cartridge. It was an attempt to create an optimal Special Operations close-to-medium range assault carbine for Close Quarter Battle (CQB). A 12-inch barreled micro-carbine and 16-inch barreled assault carbine version were created.
