7.62x39mm, 100-round drum mag. The RPK has the same design layout as the AK, but with a modified receiver and a chrome-lined, heavier, longer barrel. This is basically an assault rifle on steroids. Very effective at medium range. Gun specific mods include a composite stock and railed foregrip.
The RPK Light machine gun is one of the four LMGs and was added via with the second Gage Weapon Pack. Out of the five LMGs, it is the only one that doesn't have a reputation lock, meaning it is instantly available after the DLC has been bought.
Even when aimed in, the RPK (as with all LMGs) does not use sights, so a laser module is recommended for accurate aim (but see tips below).
Ammunition is fed from a detachable drum magazine, allowing tactical reloads. A tactical reload takes approximately 3.4 seconds, and an empty chamber reload takes approximately 4.6 seconds.
At first glance the RPK appears inferior to the Brenner 21; despite having the the same firing rate, it has a smaller magazine of 100 rounds, slightly lower accuracy, and less damage. However, it does make up with its higher stability and shorter reload time. While the Brenner 21 has a major problem with recoil on full auto, the RPK has much less and so is able to stay on target much more easily. This can be boosted even further with certain mods, making the weapon almost as stable as any assault rifle. This means that one can empty out the magazine and stay on target much more easily than either of the two other LMGs; however, the poor accuracy (relative to assault rifles) does mean a few of the shots will miss.
Properly modified, the RPK can maintain high accuracy, good stability, a modestly improved damage output, and versatility via a laser attachment for both snap- and precision-aiming. This makes the RPK capable of dishing out high damage accurately with careful aim, and the ability to unleash a powerful, wide-spread bullet storm at close range at a moment's notice.
Although the small magazine will require more reloads, the reload speed is much shorter than other LMGs (even when compared to the Brenner 21), at a speed equivalent to assault rifles, thus making tactical reloading much more viable than the two other machine guns. Indeed, properly specced, the RPK can serve as a heavy assault rifle with much greater ammunition reserves than normal, albeit with the 20% movement speed penalty while wielded.
Even when other light machine guns are unlocked, the RPK still remains a powerful tool of the trade due to its versatility. It is an incredible starting weapon that one can use on virtually any difficulty, and a weapon one might keep for quite a while as they go through heists.
One should always mount a laser module as the weapon is barely usable without it; it is impossible to aim down the sights as such, the RPK cannot accept a scope and the weapon has poor accuracy.
Zooming will tighten the spread, which helps with concentrated fire. Alternatively, when getting attacked at close range, avoid zooming-in to widen the spread, allowing the RPK to behave somewhat like an automatic shotgun.
Gadgets are mounted on the left of RPK's barrel. Players can put an Assault Light on the gun to use it as makeshift iron sight, since when zoomed the center of the screen where most bullets go to will be slightly above the assault light.
The RPK's greatest strength is having the fastest reload speed among LMGs. Utilizing tactical reload can easily overcome its small magazine size or even, arguably, make the RPK superior to other LMGs.
It is somewhat ironic that the Tactical Foregrip decreases accuracy and stability, rather than increasing it, as that is the entire purpose of such attachments. Instead, the foregrip increases damage, but how that could possibly make sense is beyond anyone's guess. This is also notable in that the vast majority of foregrips for other weapons do not improve damage output, but instead focus on accuracy, stability, concealment, and threat.

Although the main flashlight has a toggle switch, the laser sight component of the LED Combo is pressure-activated, meaning the laser will stay on as long as the pressure switch is depressed. This switch is not placed where it should be, however (on foregrips, magazine wells, etc...) and is instead ziptied to the main taclight, leaving no plausible mean for the user to toggle it without awkwardly moving their off hand off the weapon and gripping the attachment itself.
This fiberglass stock comes from the modernized RPK-74M.
The text on the modification ("Очень Секрет") reads "Very Secret" in Russian, though is grammatically incorrect with the word "секрет" being a noun and thus making no sense. A more correct rendition would be "очень секретно", although still not very smooth.
Visually speaking, the War-Torn Stock is just a Wide Stock with a few miscellaneous items bound to it by a black cable tie.
Judging by the name and its ramshackled appearance, the War-Torn Stock is likely a broken product through repeated use that was salvaged with spare parts, thus would justify its inability to keep the weapon steady during fire.
The Classic Stock is based off of the stock of the AK-74 as evident by the cut groove on the side. It is not entirely "classic", though, as even though the conception of the AK-74 is still fairly early, it is still preceded by the vastly more popular AK-47, which is a true classic.
Alternatively, "classic" here could also refer to the fact that the same stock was used by the AK in PAYDAY: The Heist.
The vanilla RPK features the integrated wooden foregrip and flash suppressor of the AES-10B - a Romanian variant.
The Plastic Stock attachment and standard 100-round drum came from a 5.45x39mm RPK-74M. The in-game drum size is slightly inflated compared to its real-world capacity of 75 rounds.
An unused magazine for the RPK is present in the game's files, only accessible by modding the game. The file name indicates that it was supposed to be the default magazine, with the drum magazine being a weapon mod. This, like the C-Mag for the CAR-4, also in the game files, would require a major reload animation change.
The RPK is one of the few guns in the game to retain its real name.
