The MK46 was first revealed in the footage released during Call of Duty XP.
Its first usable appearance is in "Bag and Drag", where it can be found in a GIGN armory, and is also carried by friendly non-playable characters. It also appears with a Foregrip in the mission "Dust to Dust", being used by Yuri, while Truck uses one in "Scorched Earth".
The MK46 is available in a default class with both a Grip and a Red Dot Sight, but is unlocked for Create-a-Class at level 54. It is also mounted on the Assault Drone point streak with a unique 50-round belt. It is a relatively versatile machine gun, having moderate to high power, the lowest recoil after the L86 LSW, good range and a high rate of fire (as with several other light machine guns, the MK46 has a faster rate of fire in multiplayer than single-player). The Grip Attachment is very useful on this light machine gun, along with the Red Dot Sight as the iron sights are somewhat obstructive. Sleight of Hand is recommended, as reload time is very long at nearly nine seconds. Quickdraw is another recommended Perk, since the ADS time of the light machine guns is generally the slowest among all other weapons. As either an alternate or an accompaniment, Steady Aim can also be a good choice to help with the bad hip fire spread typically found on light machine guns.
Similar to the L86 LSW, the Thermal Scope will drastically reduce the recoil caused by the MK46. Rapid fire brings its rate of fire up so high that in close quarters, it can beat every weapon with the exception of the PM-9 and shotguns. However, it will increase recoil significantly so it should only be used with the Thermal Scope.
Due to a recent update, all light machine guns kill in a minimum of three bullets against a normal opponent unless shooting through cover, Therefore, the only negative aspect about using a Silencer with this gun is the opportunity cost of not using another attachment.
The MK46 used to be a loadout in Infected, where it had the Kick Proficiency. The first infected in this game mode received an MK46 with Extended Mags. This loadout has since been removed from Public matches.
The MK46 is available in both Survival and Mission modes.
The MK46 is available in Survival Mode at level 34 and costs $7000. Due to its high rate of fire, low recoil, and high damage, it is a very effective weapon. Sleight of Hand is highly recommended, as with all light machine guns.

- At Call of Duty XP, the MK46 used the MG4's HUD icon from Call of Duty: Modern Warfare 2.
- The weapon's serial number is 82183 and its manufacturer's number is 14920.
- During some Special Ops missions, it will come attached with an ACOG Scope with far less zoom than normal being close to, if not identical, to iron sights zoom level.
- After the helicopter crashes into the lift in "Dust to Dust", Yuri's MK46 can be seen with every attachment on it, even with a Hybrid Sight, which is not possible to obtain in game.
- The MK46 has DO4-180 written on the side, unless golden camouflage is equipped.
- It is the second light machine gun in the Modern Warfare series to suffer from damage drop-off, after the M60E4. It has no effect on the number of shots to the body, but it does on the number of headshots, as it needs two headshots to kill at close range, but three at long range.
