The 6P62 was developed by the state-controlled Degtyarev Plant in Kovrov, built as an adaptable anti-infantry and anti-armor weapon in a lightweight and relatively compact package. It was fitted with a bipod for a ground role but also was intended to be mounted to land vehicles and boats. Although it does not appear to have been taken into general service, a photograph of Russian Spetsnaz using a 6P62 from a vehicle mount was featured in FSB photographs published in 2015, implying it may have been adopted in limited numbers by special forces.
The 6P62 is a gas-operated, magazine-fed weapon chambered for 12.7mm rounds. The round is usually identified as the 12.7×108mm, though some sources speculate it may instead be the 12.7×54mm used by the VSSK Vykhlop. The magazine holds 14 rounds. The barrel is fitted with a large muzzle device containing a suppressor-like expansion chamber and muzzle brake.
