The OKC-3S is a bayonet developed by the United States Marine Corps to replace the M7 bayonet and M9 bayonet as its service bayonet for the M16 family of rifles and M4 series carbine. This multipurpose bayonet provides greater durability than the M7 bayonet and it also functions as a fighting knife.
