Kpv 02-2-

The KPV heavy machine gun (Krupnokaliberniy Pulemyot Vladimirova, in Russian as Крупнокалиберный Пулемет Владимирова, or КПВ) is a Soviet designed 14.5x114mm-caliber heavy machine gun, which first entered service as an infantry weapon (designated PKP) in 1949. In the 1960s the infantry version was taken out of production because it was too big and heavy. It was later redesigned for anti-aircraft use, because it showed excellent results as an AA gun, with a range of 2,000 meters horizontally and 1,000 meters vertically against low flying planes. It was used in the ZPU-4, ZPU-2 and ZPU-1 anti-aircraft guns. Its size and power also made it a useful light anti-armour weapon on the BTR series of vehicles and BRDM-2 scout car.

The development of the machine gun began in 1944. The 14.5x114mm M41 cartridge can be used with High Explosive Incendiary - Tracer (HEI-T) or Armour-Piercing Incendiary (API) bullets, and they have approximately twice the energy of a 12.7 mm (.50 BMG) projectile. The KPV is air-cooled and fitted with a chromed barrel. It uses a short recoil operation system with gas assistance and a rotary bolt. It can be fed with the 40-round belt from either the left or right side. The barrel can be removed by turning the prominent latch on the forward end of the receiver and pulling on the barrel's carrying handle.
