RPK

Operating mechanism The RPK functions identically to the AK-47. It also uses the same 7.62×39mm ammunition. It has a similar design layout to the Kalashnikov series of rifles, with modifications to increase the RPK's effective range and accuracy, enhance its sustained fire capability, and strengthen the receiver. Features The RPK features a thicker and longer barrel than the AKM. This allows for it to be fired for longer without permanent loss in accuracy due to the barrel heating up. The chrome-lined barrel is permanently fixed to the receiver and cannot be replaced in the field. It is fitted with a new front sight base, and the gas block lacks both a bayonet lug and an under-barrel cleaning rod guide. The barrel also features a folding bipod mounted near the muzzle, and a front sight base with a lug that limits the bipod's rotation around the axis of the barrel. The barrel has a threaded muzzle, enabling the use of muzzle devices such as flash hiders, compensators, and blank-firing adapters. When a muzzle device is not being used, the threads on the muzzle can be covered by a thread protector. The barrel is pinned to the receiver in a modified trunnion, reinforced by ribbing, and is slightly wider than the trunnion used on the standard AKM type rifles. Symmetrical bulges on both sides of the front trunnion ensure a proper fit inside the receiver. The U-shaped receiver is stamped from a smooth sheet of steel compared to the sheet metal receiver used on the standard AKM rifles. It uses a modified AKM recoil spring assembly that consists of a rear spring guide rod from the AK and a new forward flat guide rod and coil spring. It features a thick laminated wood foregrip and a fixed laminated wood "club-foot" buttstock similar to the stock used on the RPD, which is designed to allow the user to fire from the prone position more comfortably. It uses a standard AKM pistol grip and can also use standard AKM detachable box magazines, but it is most commonly used with a 40-round box magazine or a 75-round drum magazine. Interchangeability of parts between the RPK and AKM are moderate. Sights The RPK's iron sights leaf is elevation adjustable, and graduated for ranges of 100 to 1,000 meters in 100 m increments. The rear sight leaf also features a windage adjustment knob unique to the RPK series of rifles. Accessories Supplied with the RPK are: spare magazines, a cleaning rod, cleaning kit (stored in a hollowed compartment in the buttstock), a sling, oil bottle, and magazine pouches (a single-pocket pouch for a drum magazine or a 4-pocket pouch for box magazines). ==Variants==

RPK The RPK light machine gun chambered in 7.62×39mm cartridge, is essentially a Russian equivalent to a squad automatic weapon. It was adopted by the former Soviet Union, and was issued mainly to motorized units. It was later adopted by several military agencies around the world. RPKS The RPKS ("S" — Skladnoy (Russian: складной) means "folding" stock) is a variant of the RPK with a side-folding wooden stock was intended primarily for the paratroopers. Changes to the design of the RPKS are limited only to the shoulder stock mounting, at the rear of the receiver. It uses a trunnion riveted to both receiver walls that has a socket and tang, allowing the stock to hinge on a pivot pin. The trunnion has a cut-out on the right side which is designed to engage the stock catch and lock it in place when folded. The wooden stock is mounted in a pivoting hull, which contains a catch that secures the buttstock in the extended position. The rear sling loop was moved from the left side of the stock body to the right side of the stock frame. RPK-74 The RPK-74 () was introduced in 1974 together with the AK-74 assault rifle, both chambered in 5.45×39mm intermediate cartridge. The RPK-74 was a light machine gun / squad automatic weapon based on the AK-74, with modifications that mirror those made to the AKM. The RPK-74 also uses a longer and heavier chrome-plated barrel, which has a new gas block with a gas channel at a 90° angle to the bore axis, and a ring for the cleaning rod. It is also equipped with a folding bipod and a different front sight tower. The muzzle is threaded for a flash suppressor or blank-firing device. The rear stock trunnion was strengthened and the magazine well was reinforced with steel inserts. Additionally, the RPK-74 has a modified return mechanism compared to the AK-74, which uses a new type of metal spring guide rod and recoil spring. The rear sight assembly, forward handguard and receiver dust cover were all retained from the RPK. The RPK-74 feeds from a 45-round steel or polymer box magazine, interchangeable with magazines from the AK-74, Models designated RPKN-1, RPKSN-1, RPK-74N and RPKS-74N can mount the multi-model night vision scope NSPU-3 (1PN51) while RPKN2, RPKSN2, RPK-74N2 and RPKS-74N2 can mount the multi-model night vision scope NSPUM (1PN58). RPK-201 and RPK-203 An export variant chambered in 5.56×45mm NATO was also introduced, designated as the RPK-201. A modernised export variant of the RPK was also developed, designated as the RPK-203. Both the RPK-201 and RPK-203 uses the same polymer construction as the RPK-74M. RPK-16 The RPK-16 light machine gun (the number 16 indicates the year 2016, when the development first started) is Kalashnikov's response to the "Tokar-2" program, where it competed against Degtyaryov's submission. In 2018, the Ministry of Defence of the Russian Federation have signed a contract concerning the procurement of the RPK-16, and is expected to take over the role of the RPK-74 in the Russian Armed Forces. The RPK-16 is based on the RPK-400 prototype, which shares similar design features with the AK-12 production model. It is chambered in 5.45×39mm and features the traditional Kalashnikov gas-operated long-stroke piston system, and shares several novel technical and ergonomic features derived from the AK-12 program. Picatinny rails on the top of the receiver and bottom of the handguard are used for mounting various optical sights and detachable bipods. Because of this, the fixed bipod of the RPK-74 is not needed. Other features of the RPK-16 include an ergonomic pistol grip, a folding buttstock, and two main barrel lengths: a long barrel (when it is applied or configured for the light machine gun role) and a short barrel (when it is applied or configured for the assault rifle role). Its design enables it to have interchangeable barrels that can easily be removed, and the ability to quickly attach a detachable suppressor. It has a combat weight of , a full-length of , a cyclic rate of fire of 700 rounds per minute, and an accuracy range of . The RPK-16 primarily uses a newly developed 95-round drum magazine and is also backwards compatible with box magazines from the AK-12, AK-74 and RPK-74. After receiving feedback on the performance of the RPK-16, Kalashnikov Concern began development on the RPL-20 (the number 20 indicating the year 2020) belt-fed light machine gun, chambered in 5.45×39mm cartridge. It features rate of fire of 800 rounds per minute, an empty weight of , an open-bolt design and quick-change barrels to enhance sustained fire. Kalashnikov Concern has so far created at least one functional prototype. The RPL-20 has become the first light machine gun to be used by Russian forces since the RPD machine gun that isn't magazine-fed or of the standard Kalashnikov pattern. Foreign production Bulgaria The RPK is produced by Arsenal as the LMG in three different calibers, 7.62×39mm, 5.45×39mm and 5.56×45mm NATO. The Arsenal LMGs are equipped with milled receivers. Their folding stock variants are known as the LMG-F. East Germany The RPK was produced locally in East Germany as the LMGK (). Iraq The RPK is manufactured locally in Iraq as Al Quds. North Korea The RPK is manufactured locally in North Korea as the Type 64. Later, a 5.45mm RPK-74 version based on the PA md. 86, the Mitralieră md. 1993 (), was also developed. Serbia The Zastava M72 was based on the RPK, and developed from the Zastava M70. ==Users==
