Metallic Links and Clips

a. Metallic links (fig. 3-15 and 3-16) are used with caliber .30, caliber .50, 5.56-mm, 7.62-mm and 20-mm cartridges in machine guns. The links are made of steel, surface treated for rust prevention. They are used to assemble cartridges into linked belts of 100 to 750 cartridges per belt. The links must meet specific test and dimension requirements to assure satisfactory ammunition feed and functioning in the machine gun under all training and combat service conditions.

b. Different configurations of cartridge clips permit unitized packages of ammunition. This facilitates transfer of cartridges to appropriate magazines for caliber .30, 7.62-mm and 5.56-mm -rifles. The caliber .30 eight-round clip feeds eight cartridges as a unit into the receiver of the rifle.
