 As was the trend with American belt-fed firearms, as opposed to Soviet designs, belts of ammunition feed into the gun from the left side to the right.The left side of a single link had a circular loop which would hold the main body of the cartridge case, and an extension on the right that formed two similar loops which was designed to fit in between the two right-side loops of the next link.The rear loop of the right side of the link would hold onto the cartridge case just below the shoulder, as would the left side loop, where the front loop of the left side of the link held onto the cartridge neck, and was therefore a bit smaller in diameter.
