RPK

The RPK, or Ruchnoy Pulemyot Kalashnikova (Russian: Ручной пулемёт Калашникова; English: Kalashnikov hand-held machine gun) is a Soviet/Russian light machine gun, developed by Mikhail Kalashnikov in the late 1950s. It was put into service with the Soviet Army in 1961. Several countries have copied the design and were produced, as well as many others exported, especially after the Soviet Army replaced it with the RPK-74, which, it too was copied and exported, especially to Asian, Middle-Eastern, African and East European countries.

The RPK fires the 7.62x39mm cartridge from a 40-round box magazine or 75-round drum magazine. The RPK-74 uses the 5.45x39mm cartridge which is loaded into 45 round box magazines and can also be used in a prototype 100-round drum magazine (this never entered production). These magazines are fully compatible with other AK variants of the same caliber, as well as several other Russian style small arms. They have an effective range of around 100–800 meters (RPK-74 effective range being longer than the RPK due to the newer ammunition), and share many of the traits of the Kalashnikov rifles. A heavier, longer barrel and reinforced receiver allow it to stand up to the heavier firing it's role requires. While not the most accurate LMG, it is more than capable of hitting targets accuratly in typical combat ranges.

Battlefield 2
"The RPK is a very efficient squad level light support weapon using small-caliber ammunition. Due to its high rate of fire, the RPK is most accurate when fired from a prone, stationary position."

- In-game description

The RPK-74 appears in Battlefield 2 as the main weapon for the MEC's Support Kit. Like the other light machineguns, it boasts relatively low spread while proned, although its standing and crouching spread are higher than most other classes of weapon, as well as relatively high damage and a longer than average reload cycle.

The RPK-74 also comes in a mounted versions on some MEC-related maps. Like the mounted M249 and QBB-95, the mounted RPK-74 has a high rate of fire and decent accuracy with virtually no recoil, as well as infinite ammo. It also has no ironsights and is prone to overheating.

Battlefield 2: Special Forces
In Battlefield 2: Special Forces, the RPK-74 is the default support weapon for MEC Special Forces, Spetsnaz, Rebel Forces and Insurgent Forces.

Battlefield: Bad Company 2: Vietnam
In Battlefield: Bad Company 2: Vietnam, the RPK is a weapon for the Medic Kit. It is the equivalent of the PKM LMG in the base game, the only differences being appearance and the RPK's faster reload time. Like most weapons in the expansion, the RPK appears rusted and the receiver cover is held in place with cloth. DICE developers explained that it was a distinct art style for the weapons in the Vietnam expansion. It differentiates from the other two MG's by having a round drum magazine rather than a box with a belt of ammunition, and as such retains the LMGs' high capacity and has a quicker reload time. The RPK is between the M60 and XM22 for firing rate and recoil making it a balance between the high accuracy and damage of the M60 and the fast firing rate of the XM22. The weapon's iron sights are comparably clearer than other light machine guns, and are similar to the AK47's. The RPK has the same firing sound as the PKM in the base game.

Battlefield 3
"The RPK-74M is an improved version of the original RPK developed in the 1950s. Essentially a heavy barreled AK-74, the RPK fires from a longer magazine and has been equipped with polymer grips to lighten the weapon. The RPK-74M also features the same scope mount as the AK-74M and is equipped with a bipod by default for supported shooting."

- Battlelog description

In Battlefield 3, the RPK makes its third appearance in the Battlefield series as the RPK-74M.

Singleplayer
The RPK-74M is the most common light machine gun and is commonly used by every faction, apart from the Gendarmerie, GIGN, and USMC. It can be found with any number of attachments and optics.

Multiplayer
The RPK-74M is the default light machine gun of the Russian Army, functioning as the counterpart of the M27 IAR of the USMC. It is unlocked for the USMC upon achieving 170,000 points with the Support kit.

The two function in a similar manner, having a 45+1 round magazine and being fed by a box magazine as opposed to a belt, giving it a faster reload than the other LMGs. It has a slower rate of fire, but much less recoil than the M27. Like the other light machine guns, the RPK comes default with a bipod. The very smooth recoil and high degree of accuracy (with or without the bipod deployed) allows the RPK-74M superior performance when engaging specific targets or enemies at longer range when compared to other weapons in the Support Class.

Patches
The RPK-74M and M27 IAR were the only light machine guns that did not unlock the Extended Magazine accessory. The 1.04 patch (March 2012) mistakenly enabled the RPK to equip Extended Mags, allowing it to use 200 rounds. This was fixed in the 1.05 patch (June 2012). As of patch 1.06 (September 2012), the RPK now has 60+1 rounds with Extended Magazine and is now also able to unlock the heavy barrel.

The QBB-95, and MG36 were the opposite; they started with Extended Magazines but later got them removed - however, DICE later added a heavy barrel unlock and re-added the extended mags for these two guns.

Battlefield 4
The RPK-12 is a light machine gun set to appear in Battlefield 4. It was first seen in the Battlefield 4: "Paracel Storm" Multiplayer Trailer at Gamescom 2013. The RPK-12, just like the other AK-12 variants could use different sized barrels to fire different caliber rounds. The in game model is fitted with a barrel that fires the 7.62 x 39 round, but uses the 5.45x39mm WP round and casket magazines.

Trivia

 * In Battlefield 3, since the beta, the reload animation slightly changed. In the beta, the gun was tilted to the side and the bolt was pulled back, identical to that of the Saiga 12K's animation. In the retail version, the RPK-74M is still held in a firing position with the right hand, while the left hand is used to pull back the bolt.
 * In Battlefield 3, the RPK-74M's bolt does not move when being fired, which is likely a design oversight on DICE's part. This is noticed on every machine gun and visible when the weapon's bipod is down and it is moved to the right and fired.
 * In Battlefield 3, the RPK-74M was originally called RPK, after the gun it was modeled on.
 * In Battlefield: Bad Company 2: Vietnam, the RPK's iron sights are misaligned just like the AK-47 in the same game.
 * In Battlefield 3, the RPK-74M equpped with Extended Magazine appears to be firing from a casket magazine.
