12.7-mm  NSVP-12.7  machine gun is designed to eliminate enemy light armored targets, vehicles and group forces at ranges up to 2,000 meters, engaging sea and airial targets at slant ranges and also for anti-tank vehicles and group manpower.

The machine gun allows you to shoot in lying position from trenches of different densities or from a trench on foot, sitting and knee firing positions, specially designed trenches, semi-trenches or positions suitable for firing.

The machine gun is served by a two-man crew consisting of a gunner and an assistant. When changing the firing position in combat conditions, the machine gun is carried by the crew members.

The basic ammunition used for the machine gun is 12.7x108 mm armored-piercing incendiary (B-32), armored-piercing incendiary tracer (BZT-44 or BZT-44M) bullet cartridges.

The machine gun is fired by short bursts up to 4 – 6 shots.   During firing the machine gun barrel is cooled by air and provides continuous firing up to 100 shots.

The machine gun is aimed at the target with an optical sight of the SPP or PO3,5x21P and in case of failure is replaced with mechanical sight.

During firing, the cartridges are transferred to the machine gun receiver via a steel belt assembled in the cartridge box with a capacity of 50 bullets.

The optical sight works in the different climatic conditions at a temperature of ± 50 °C and a relative humidity of 95 ± 3%.
