"Full-auto assault rifle. High damage at short range with moderate recoil."
— In-game description

The KN-57 is an assault rifle featured in Call of Duty: Black Ops 4. It has a Mastercraft variation called the "Kuromaku" that is available from Reserve Crates.


  • Ammo (Blackout): 7.62mm
  • Operator Mod: None


The KN-57 is available at Level 10, or from Level 1 as part of the default classes. For the most part, it handles similarly to its counterpart, the KN-44, and fulfills the same role within multiplayer as a middle-of-the-road assault rifle with no particular standout strengths or weaknesses. At point-blank range, the weapon takes four shots to kill but quickly drops off to five. These stats result in an average time-to-kill for the assault rifles and allows the weapon to be effective in close-quarters engagements. 

The weapon has a rate of fire around 555 RPM, which is around average for the assault rifle category and pushes its effective engagement range out to a close-medium range.

Recoil manifests as a constant pull upwards and is easily manageable, but may hinder accuracy at longer ranges.

Handling is somewhat average for the assault rifle category. The KN-57's reload time is around average for the assault rifle category, and the weapon does not suffer from any glaring deficiencies on the aspect of handling. As with most weapons, the Quickdraw and Grip are never bad choices and serve to increase the KN-57's reliability at close and medium ranges, respectively. 

The KN-57 is a "jack of all trades, master of none" rifle that can be used well in most engagement scenarios, although other weapons outclass it in their respective strengths. It is a fantastic starter weapon and is easily accessible for newer players and veterans alike. In addition, it has the unique ability to simultaneously equip Extended Mags and Hybrid Mags in multiplayer, giving it a whopping capacity of 65 rounds.





The KN-57 appears in the zombie maps Voyage of Despair, IX, Blood of the Dead, and Classified, where it's available as a weapon within the Mystery Box for 950 points. When upgraded via Pack-a-Punch Machine, it becomes the Ruined Revenger with the magazine size increased to 75 rounds and its ammo reserve increased to 350. It is unlocked for customization in the armory at level 21.
