With the Operator Mods, weapons in the multiplayer of Call of Duty: Black Ops 4 can be significantly upgraded. But what Operator Mods are available? How can you obtain them? And what do they do in detail?
The Operator Mods represent an additional customization option for parts of your arsenal in the traditional multiplayer part of Black Ops 4. They all offer unique bonuses, can significantly alter certain weapon characteristics, and thus allow for entirely new playstyles. We have compiled everything you need to know about the Operator Mods for you.
The Operator Mods in Call of Duty: Black Ops 4 – What You Need to Know
What are Operator Mods? These are special modifications for specific weapons. A weapon can have a maximum of one Operator Mod. However, not every weapon has this modification. Currently, 18 firearms have the option to equip such a mod. Whether more will be added in the future is not yet known.
That’s why Operator Mods are worth it: The bonuses are all unique and range from a change in fire rate, to a bayonet for extra melee damage, to incendiary ammunition with fire damage. In numerous situations, they can determine victory or defeat in direct duels with one or more opponents.
With the Operator Mod, for example, the already solid Revolver Mozu becomes an absolute killing machine and one of the best weapons in the game.

This is how you obtain the Operator Mods in Black Ops 4: To do this, you must first level up the corresponding weapon to the highest weapon level. There’s no way around it. Only then will this modification be unlocked.
Additionally, you will also need the respective wildcard, either “Primary Operator Mod” or “Secondary Operator Mod.” Only then will the corresponding mod slot for the weapon be unlocked, and you can select it among the attachments.
Keep in mind that the Operator Mod itself already occupies 2 slots on the weapon. The wildcard also requires an additional slot in the Pick-10 system. So, the mod is not just a bonus on top. To use it, you must necessarily forgo other options in your loadout.
All currently available Operator Mods in Black Ops 4 – What They Can Do
Here you will find a list of all weapons that currently have an Operator Mod. Additionally, you will learn what the respective operator mod does to the weapon.

All Operator Mods for Assault Rifles in Black Ops 4
Vapr XKG (Assault Rifle): The Operator Mod for this assault rifle is called Bayonet. This gives the weapon the namesake bayonet as an attachment, making every melee hit lethal.
Maddox RFB (Assault Rifle): The Operator Mod of the Maddox is called Echo Fire. This gives the rifle a special recoil system that fires every second bullet from the magazine at increased velocity. Thus, the weapon fires significantly faster, but you will have to deal with heavy recoil.
All Operator Mods for Submachine Guns in Black Ops 4
GKS (Submachine Gun): The Operator Mod for this SMG is called Quad Shot. With this modification, the otherwise fully automatic SMG fires bursts of 4 projectiles each. This makes the weapon more precise. Additionally, the damage drop-off of the submachine gun occurs only at greater distances.

Spitfire (Submachine Gun): The corresponding Operator Mod is called Wild Fire. This greatly increases the fire rate of the weapon. At close range, the weapon becomes absolutely lethal. But watch out, the magazine runs out just as quickly as the Spitfire shoots now.
Cordite (Submachine Gun): The Cordite has the Ammo Belt as its Operator Mod. This gives the weapon an immense amount of ammunition and completely eliminates the need to reload.
However, with sustained fire (after 75 continuous shots) the weapon can overheat and must cool down before you can continue firing with it. The heat indicator is located right next to the ammunition display.
Saug 9mm (Submachine Gun): The Operator Mod of the Saug is called Two-Handed. As the name suggests, you can wield two of these submachine guns simultaneously. You can fire one weapon individually or both at the same time.
While you can no longer use the sighting device with two weapons, everything that gets in your way in close range simply melts away.
All Operator Mods for Tactical Rifles in Black Ops 4
Auger DMR (Tactical Rifle): The respective Operator Mod is called Double Shot. This allows the weapon to fire a 2-shot burst. The precision is still maintained, making this already deadly weapon even better and noticeably reducing the time to kill. In short: One of the best Operator Mods and an absolute must-have.

ABR 223 (Tactical Rifle): The ABR comes with the Operator Mod Repeater. With this modification, the weapon receives an advanced trigger system, allowing the fire rate to increase with each subsequent burst as you hold down the fire button. In short: The longer you hold the trigger, the faster the ABR fires.
Swordfish (Tactical Rifle): This weapon has the 5-Shot Burst as its Operator Mod. This gives the already burst-firing weapon an additional 5th bullet per burst. Additionally, there is an increased ammunition capacity. The weapon remains very precise.
This Operator Mod is also among the best in the game. Because the Swordfish requires 5 bullets to eliminate an enemy, but normally only 4 shots are fired per burst. With the Operator Mod, you can eliminate an enemy with just one burst.
All Operator Mods for Light Machine Guns in Black Ops 4

Titan (Light LMG): The Operator Mod of the Titan is called Suppressor. Enemies who are near the weapon’s firing path are suppressed by the mod. Specifically, this means that your opponent’s view is slightly distorted.
Hades (Light LMG): With the Hades, you can unlock the Vertical Grip as an Operator Mod. This means you can no longer aim through the sight, but the weapon gains a focused view and reduced spread when shooting from the hip. Additionally, you can move faster.
VKM 750 (Light LMG): As an Operator Mod, it offers the Fat Barrel. This fires massive projectiles that hit your opponents more easily. In practice, this means the hitbox of your opponent is slightly increased, and some projectiles that would otherwise have missed now hit.
All Operator Mods for Sniper Rifles in Black Ops 4
Outlaw (Sniper Rifle): For the Outlaw, the Operator Mod is called Bolt Cylinder. This fires three shots with each press of the fire button. Additionally, holding the button is supposed to result in automatic burst fire.
However, this function is either faulty or not activated. Because holding the button has no effect on the shooting behavior of the Outlaw.
Koshka (Sniper Rifle): The Operator Mod of the Koshka is called Strelok and is supposed to provide additional precision and accuracy when switching to aiming view. However, this mod does not have a really noticeable effect. Fans suspect that it might provide additional aim assist.
All Operator Mods for Pistols in Black Ops 4

Unfriede (Pistol): For this pistol, the Operator Mod is called Stiletto. Just like the Vapr assault rifle, every melee hit becomes lethal.
Mozu (Pistol): The Operator Mod Skullbreaker makes the Mozu one of the best weapons in the entire game. Because with this modification, every headshot from the weapon is lethal.
It does not matter if the opponent is behind a wall (that can be penetrated), wearing armor, or how far away the opponent is – every headshot kills instantly.
All Operator Mods for Shotguns in Black Ops 4
MOG 12 (Shotgun): With its Operator Mod Dragon’s Breath, the MOG 12 fires incendiary ammunition that additionally damages the target over time. However, the additional damage is very low. The only real advantage: For the duration of the effect, the target cannot heal.
SG12 (Shotgun): For this shotgun, the Operator Mod is called Strobe Light. With this modification, you can no longer use the weapon’s sighting device.
Instead, when holding the aim button, a bright flashing light activates that severely restricts your opponent’s visibility. The effect is truly powerful and very annoying for any opponent who engages you in close combat.
