The Kord-12.7 mm heavy machine gun is a Russian design that entered service in 1998^[3] replacing the older NSV machine gun. Externally the weapon resembles the NSV; however, the internal mechanism has been extensively reworked, changing from a horizontally pivoting breech block to a rotating bolt design.^[3] Additionally the gas system has been changed and the muzzle baffle redesigned. These changes give the weapon reduced recoil compared with the NSV, allowing greater accuracy during sustained fire.
