The 6P50-2 Kord is a Russian 12.7 mm heavy machine gun designation in the Kord family, manufactured by V.A. Degtyarev Plant. The Kord family was developed as a Russian replacement for the Soviet NSV after the main NSV production base was outside Russia, and Rosoboronexport lists the weapon with 12.7x108 mm ammunition, a 2,000 m sighting range, 10,000-round barrel life, and 32.5 kg weight. RussianShips.info identifies the 6P50-2 aboard IC16MII boats P-834 and P-835.
The Kord family keeps the Russian 12.7x108 mm heavy-machine-gun role while changing the mechanism and mounting package from the older NSV line. The 6P50-2 page is kept as a relationship-only support record because the available direct sources identify the designation, cartridge, technical data, and carrier fits more clearly than they document conflict use by this exact designation.
Forgotten Weapons describes the Kord as a long-stroke gas-piston gun with a rotating bolt.
The forward-ejection design is noted as useful for armored-vehicle installation, while Rosoboronexport states the weapon can be installed on multiple mounts and vehicles.
RussianShips.info directly names 6P50-2 on IC16MII boats; broader Kord combat reports are not treated here as proof for this exact designation.
Specialist references treat the Kord family as one 12.7 mm heavy machine gun adapted to vehicle, coaxial, bipod, tripod, pintle, and pedestal mounting arrangements; the 6P50-2 designation is associated with the 6P58 configuration.
