The AK-21 is an Assault Rifle featured in Call of Duty: Anihilation
Multiplayer[]
Like the ARX-16, the AK-21 is capable of firing in both fully automatic and semi automatic modes. It has slightly more vertical recoil than the ARX-16, but also has less first shot recoil. This lower first shot recoil, combined with its lower fire rate, makes the AK-21 easier to handle controlled bursts at range when compared to the ARX-16. Its open sights provide a clear view of the target which also adds to its ease of use.
