PB
The silent self-loading pistol (silent pistol, Index 6P9) was developed by designer A.A. Deryagin with the use of elements of the PM and adopted for service in 1967.
The PB features a two-section silencer. The muzzle is provided with a jacket-expan¬sion chamber. The operation of such an inte¬gration silencer is based on the preliminary escape of the exhausted gases from the bar¬rel bore, thereby reducing the pressure of powder gases and velocity of the bullet (up to 290 m/sec, that is lower than the sound velocity). The chamber is located on the front part of the pistol barrel-slide, powder gases are escaping from it through grooves rifled at the bottom of the barrel-slide. Between the slide and the barrel there is a jacket roll of
metallic gauze to absorb the temperature of exhausted gasses. The detachable unit is fixed to the front part of the chamber which constitutes a silencer unit-nozzle housing with a separator with several washers arranged at various angles of inclination. In the chambers of the nozzle the exhausted gases are being separated, expanded and gradually lose its velocity and temperature.

AGS-30
The AGS-30 more light mounted grenade launcher (grenade launcher complex) was developed at the Tula-base KB Instrument Design Bureau chambered either for the same rounds VOG-17 and VOG-17M or the new one, VOG-30. The ballistics of the grenade launcher remained intact. The grenade launcher is a blowback operated weapon, the weight of the bolt is increased at the expense of the round and the sear. The shot fired from the “counter-rcoil thrust” and a long travel of the bolt make the operation of the weapon’s moving parts more smooth and enhance the accuracy of fire. The firing mechanism permits only automatic mode of fire. The hammer is cocked by a rock¬ing lever. The AGS-30 unlike the AGS-17 does not have any hydraulic mechanisms. The belt is loaded with 30 rounds.

RGS-50M
EG-50M blow-chock effect, and later on completed with the rounds featuring grenades GO-50 of splinter effect, GK-50 hollow or shaped charge effect, GV-50 rounds intended to break out locks and the GD-50, smoke-type grenades. So, this special grenade launcher intended for police and counterterrorists’s opera¬tions acquired new combat qualities.
This grenade launcher is developed on a single-load short shotgun configuration with a hinged barrel and an upper rotating locking lever. Its firing mechanism is of a hammer type, with a non-automatic thumb safety (located to the left over the trigger) which holds the sear. The hammer is being cocked when the barrel is hinged to break open and after a shot it assumes a released position (so that the striker doesn’t hamper unlocking). The fired cartridge case is extracted by an extractor.
The pistol grip and removable fore grip are intended for control of the weapon. The detachable tube-shaped stock is located along the line of axis of the barrel bore and compatible with a spring-actuated recoil break and outfitted with the rubber butt-stock which permitted to launch compara¬tively heavy (0.39-0.42 kg) grenades with the muzzle velocity 90 m/sec.

GP-25
The GP-25 «Koster» underbarrel grenade launcher was adopted (or service in 1978 which was developed at the TsKIB SOO by V. N. Telesh to be employed in the complex with the AKM, AKMS, AK-47 and AKS-74 assault rifles. The Tula-based Ordnance Plant (Armory) had launched the grenade launcher in production.
The GP-25 (Index 6G15) is noted for its simple design and is classed as a muzzle loaded rifled weapon systems.
The VOG-25 or VOG-25P round developed at the GNPP «Pribor» incorporates a grenade and a propellant charge in a case and is being inserted in a barrel without force, thus entering by its 12-lugs of the driving band into the barrel grooves and is being retained in the barrel tube by a spring-actuated latch.

Kord
Inasmuchas since from the early 1990s the main manufacturer of the NSV-12.7 machine guns was left in the «sovereign» Kazakhstan, a team of designers, including A.A. Namitulin, N.M. Obidin, Yu.M. Bogdanov and V.I. Zhirochin had performed work at Central Design Bureau (SKB) of the Kovrov Plant named after V.A. Degtayrev under the code name «KORD- (”large caliber weapon of Degtyarev followers) intended to modernize the NSV machine gun to launch it in the new production process.
The rapidly replaced barrel was made in con¬formity with the so-called ZID (Degtayrev Plant) method of production ensuring the gradual heating and insignificant thermal warpages. The new barrel with the flash suppressor-compernsator and a somewhat updated locking system by the wedge bolt enhanced accuracy by a factor of 1.5-2 from the same mount as compared with the NSV machine gun while retaining the weight of the «KORD» machine gun «body° within 25.5 kg. Some reduction in the rate of fire was compensated by ease of the weapon operation.
The firing mechanism features a safety lever to exclude a discharge in the event of accidental trig¬ger squeeze. The cartridge-belt is fed either from the right or from the left side. The open iron curve-slide sight intended for firing at a range of 2,000 meters serves as the main sight while other sights like optical, night, and collimating ones are optional.
The «KORD» (6P50) is being manufactured since 1998, it underwent the combat tests and was adopted for service in 2001. The «KORD» (6P50) variant on the 6T19 bipods has overall weight of 32 kg, the 6P50-2 variant on the universal mount 6U16 (employed against ground and air targets) weighs 52 kg, the 6P50-3 variant on the universal pedestal weighs 75 kg. The pintle mount for a cartridge box, cartrige belt and cartridge case bag may be maby installed on transport vehicles and small vessels. Tank «KORD» 6P49 of 1,625 mm long and 27 kg weight (mounted on Т-90 МВТ tank). Actually, the first large caliber general-purpose machine gun came into being.
There is an «export» variant of the «KORD-chambered for the American cartridge .50 “brown¬ing. (12.7×99).

NSV-12
In 1972 a machine gun developed by G.I. Nikilin, Yu.M. Sokolovand V.I. Volkovwas adopted for service to replace the 12.7mm DShKM machine gun and it was designated NSV-12.7 (Nikitin-Sokolov-Volkov, 12.7 mm, code name -Utes>, Index 6P11).
The machine gun Is a gas-operated weapon with a long travel of its piston and a gas-regula¬tor. In an effort to make the fully automated parts more smooth operated the bolt carrier was provided with the guide rollers and the return mechanism with a piston buffer spring. The barrel is of a removable type. The locking of the barrel is ensured via the skew of the bolt to the left. The firing mechanism is assembled in a separate housing and ensures only auto¬matic mode of fire actuated whether by an elec¬tric or manual triggers. The shot is fired from the rear sear. The safety thumb locks the sear.
The weapon is fed from a metallic cartridge-belt either from the right side or from the left side. The refuse from the versatile mount made the NSV-S-12.7 mounted version more manoeu¬vrable. The 6T7 tripod mount developed by L.V. Stepanov and K.A. Barishev is intended to defeat ground targets, it is provided with the stock of its own, control grip, firing mechanism and the sight bracket intended to mount the SPP optical sight, NSPU-3 (1PN51) night sight or NSPU-5 (1PN83).

Pecheneg
The team of developers at the TsNIITOCHMASH, including A.A. Deriagin, N.N. Denisov, V.I. Suslov, M.V. Chugunov, A.S. Neugodov and others had undertook a num¬ber of measures directed to enhance the accuracy of the PKM machine gun as well as the service life of its barrel and to reduce the errors in its aiming at the target. As a result of the thrust came into being the Kalashnikov infantry machine-gun «Pecheneg» with its subsequent formal Index 6P41.
The innovations in the design of a barrel and introduction of the jackets had enhanced its ruggedness, improved its cooling, protected from atmospheric effects, reduced its own reverberations, protected its line of sight from effects of a «mirage» effect. The clearance between the jacket and the outer space of the barrel, its transversal ribs and the ejector near its muzzle ensure its enforced and gradual cooling by an ambient air.

PKMT
As the PK was adopted with the PKT (Index 6P7) tank machine gun and the PKB (6B10) armored personnel carrier machine gun, so together with the PKM appeared the PKMT (6P7M) tank machine gun and the PKMB (6P10M) armored personnel carrier machine gun. The tank machine gun features a more heavy barrel that permits to deliver more intensive fire. Its gas-regulator operates on the principle of changing the cross-section of the gas-bleeder and not on the principle of gases exhaust as was the case with the PK and PKM machine guns in an effort to prevent extra gas pollution in the combat compartment of the tank. The
PKMT does not have the sighting aids of its own, the operating handle and the stock, the appearance of the receiver is changed. The spring of the guiding tube of a piston rod removes the gap or the clearance between the tube and the receiver. The PKMT is equipped with an electric trigger mechanism. The tank machine gun is employed as the coaxial and the course weapon on the remotely controlled mounts.
The PKMT was manufactured at the Kovrov Mechanical Plant and the Zlataust Machine-Building Plant.
The PKMT weighs without ammunition load 11.705 kg.
