(adsbygoogle = window.adsbygoogle || []).push({}); The AK74u appears in Call of Duty: Black Ops, however the name has no hyphen like its Call of Duty 4 counterpart. It no longer has a stock attached. Its finish is also different from its Call of duty 4 counterpart, including the default magazine; the metal is shinier and is silver-gray, compared to black-gray in Call of Duty 4 .

CampaignEdit
The AK74u appears in the levels "Crash Site", "Rebirth" and "Redemption." It is used commonly by Viet Cong and Spetsnaz forces.

MultiplayerEdit
The AK74u is made available for purchase upon reaching level 17, and costs 2000. It has the second most amount of damage for a submachine gun, tied with the MP5k, and losing only to the Skorpion at close ranges. It has a predictable upwards recoil pattern which is relatively easy to control. It performs exceptionally well at close to mid ranges, though its recoil and damage drop-off make it harder to use at long distances. The Grip attachment mitigates this problem by greatly reducing recoil, which helps to ensure more shots stay on target. The AK74u has a slower rate of fire compared to most submachine guns, however this can help with conservation of ammunition, if you are accurate with your shots. But this too can be mitigated with the Rapid Fire attachment. The AK74u is the only submachine gun for which the Grenade Launcher attachment is available. It is also one of only two submachine guns which accept the Dual Mag attachment (the other one being the MPL).
Many of its traits make it play like an assault rifle with submachine gun ADS and movement speed, making it one of the most popular weapons in multiplayer. The reload time, iron sights , and assault rifle-like traits of this weapon make it one of the best options for new and experienced players alike. Unlike assault rifles, it is important to note the AK74u has lower bullet penetration. It is unable to penetrate through medium and high surfaces such as building structures and concrete slabs, although it is reasonable when shooting through light material. This problem can be remedied by using the Hardened perk.

The AK74u is available off the wall for 1200 points. It has low recoil, a moderate rate of fire, a 20 round magazine with 160 reserve rounds and low damage. It is an effective weapon for the early rounds. It is not advised to use it after Round 8, as it becomes too weak. Pack-a-Punching it will give it the name "AK-74fu2," with double its ammo, and an added Red Dot Sight with a unique randomized reticle. The name "AK-74fu2" is very similar to the Internet slang "FU2" which means "**** you too", often used when players are insulted. Ammo runs out fairly quickly, so careful conservation of bullets is advised.
