The Degtyarev plant (officially the Open Joint Stock Company "V. A. Degtyarev Plant", Russian: ОАО Завод имени В. А. Дегтярёва, commonly abbreviated as ЗиД (ZiD), English: Presently the Degtyarev plant is producing revolvers, machine guns, aircraft guns, anti-aircraft guns, anti-tank guns and rocket systems. The plant also makes a range of civilian products: motorcycles (i.e. Voskhod), mopeds, micro-tractors, sewing machines and accumulator batteries. Products[edit] KSVK sniper rifle PTRD Kord machine gun PKM PPSh-41 PKP "Pecheneg" AEK rifle series AGS-30 AEK-919K "Kashtan" RPG-7V2 SP81 flare gun SVT40 The Kord-12.7 mm heavy machine gun is a Russian design that entered service in 1998[2] 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.[2] 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.The catalyst for the development of the weapon was a complete lack of any heavy machine guns in construction at that time in the Russian Federation. Prior to the dissolution of the Soviet Union, the weapon that had functioned as the heavy machine gun was the NSV, or "Utes" or "Utjos" (meaning one lonely cliff in Russian, this name was its designation during development)[3] (утёс) machine gun. The main production centre for the NSV was located in what is now Kazakhstan.[2] The Russian Degtyarev bureau was given the job of producing an updated version of the weapon chambered in the 12.7×108mm cartridge, which could be used for support, mounted on vehicles or in an anti-aircraft capacity. The weapon has also been chambered to handle the .50 BMG cartridge for export sales. The weapon employs new construction, and consequently is significantly lighter than its predecessor. The firing mechanism is very rugged, yet is capable of a greater rate of fire and significantly less recoil. Because a new barrel made of a high-tech alloy minimizes distortion and drop, accuracy has increased tremendously over previous Soviet machine guns. Unlike its predecessor, it may be fired from a bipod — a rather unusual feature for 12.7 mm/.50 caliber heavy machine guns. Its relatively light weight and lesser recoil allows stronger soldiers to move the gun around without assistance.[4] Variants[edit] 6P49: Baseline variant for vehicle mounting.[2] 6P50: Bare infantry version.[2] 6P50-1 (6P57): 6T19 Bipod-mounted infantry version. Bipod provides +/-15° range of traverse.[2] 6P50-2 (6P58): Infantry variant.[2] 6P50-3 (6P59): Infantry version on a 6U16 multipurpose mount. Casing ejection is to the right side.[2] 6P51: Co-axial version with left-hand feed system and forward casing ejection.[2] The AGS-30 is a Russian-designed automatic grenade launcher currently in production in the Russian Federation and in service with the Russian armed forces.Designed on the basis of AGS-17, the AGS-30 provides better mobility, longer range and better accuracy during firing. Significantly lighter than its previous version but far more advanced and powerful, the AGS-30 weighs 30 kg loaded, meaning it can be carried by one person. Using a specially designed GPD-30 grenade, recently[when?] put into serial production,[2] the AGS-30 can engage targets at over 2000m. Recoil is lessened with a much smoother grenade ejection mechanism. An adjustable SAG-30 tripod mount (GRAU index 6P17) is also included. Development[edit] After the dissolution of the USSR, Russia found itself in a difficult position in the First Chechen war. After the success of the AGS-17 in Afghanistan, the KBP Instrument Design Bureau immediately began work on the new grenade launcher. The Russian army needed a weapon that could easily flush militants out of their fortified building hideouts, levelling them in seconds.
