The Krinkov has incredibly high base damage for an SMG, on par with the Swedish K, Jackal, Tatonka and the CR 805B. It also has a good variety of mods, an ample magazine size, and good accuracy. However, it severely lacks in both total ammo and stability. With the right mods, it can make a useful "pocket AK.762", albeit with a much higher fire rate, and lower accuracy, stability, and modability. As a matter of fact, due to this high base damage and accuracy, but low ammo and stability, it is one of the few -- if not the only -- SMG where the single-fire mod is viable.
However, it has a major flaw in its low amount of total ammo; it only has three full magazines' worth of ammo before running out. It also has some of the worst recoil of all the submachine guns, only beaten out by the Mark 10.
To get the most out of the low reserve ammo, it is recommended that one increase the already high damage of the Krinkov and to always go for head shots, unless in an emergency. For longer ranges, one should try to burst fire to keep the recoil in check and save ammo, or use semi-auto mode.
It is a viable secondary weapon for Plan A, due to its high concealment, and its massive damage makes Plan B a good choice too.
*The LED Combo is based on the Leapers, Inc. UTG LED Weapon light and Laser. **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.
*Upon release, the default reticle of this sight was a chevron instead of the retail version's red dot. After the release of the Gage Mod Courier DLC, it was reverted to the regular sight's red dot. *It is functionally the same as the standard Military Red Dot Sight, but the sight's casing is tan instead of black with the line "A-10" scrawled on near the adjustment knob. The sticker on the lens cap's interior also says "I <3 Payday" instead of having a picture of an American flag. *This sight was based on the Aimpoint CompM2 optic. While it is portrayed as a high-zoom scope in-game, the CompM2 is actually a reflex sight, meaning it offers no magnification in reality.
The Acough has the greatest zoom in the game for a non-sniper scope. That being said; the high zoom level combined with its bulky sight casing can hamper target acquisition at point blank range, pairing the scope with a laser sight can dramatically alleviate this potential difficulty.
The Razor Splitter has an image of a razor blade on its default scope, which is commonly associated with cocaine, indicating that it may have been made by Jimmy.
The Gray Hunter skin is strongly implied to have been owned by Chains himself, or at least mocked up to resemble a similar weapon he once used as evident by the words "U.S. Enforcer Nicolas" printed on its receiver.
The Krinkov is based on the AKMSU, as indicated by its internal name in the weapon asset files and the AKMS's ribbed cover. Being essentially an aftermarket-modified AKM(S), this would explain the weapon's high damage per shot and its severe recoil.
"Krinkov" is a nickname of Middle-Eastern origin fashioned from several different and progressively shorter attempts at pronouncing the name "Kalashnikov" in Pashtu. Nowadays it is used as a shorthand term to identify most AK variants.
Barrel Extensions fitted onto the Krinkov will sit in front of the weapon's stock flash hider. This is actually a more realistic depiction of the AKMSU as the muzzle device contains an expansion chamber to correctly cycle the carbine, which makes it a requisite component rather than cosmetic.
Despite being a carbine, it is noted as a sub-machine gun in-game alongside the Para.
