HK21

The HK21 is a West German light machine gun featured in Call of Duty: Black Ops.

Multiplayer
The HK21 is a fully automatic light machine gun with moderate recoil, moderate rate of fire and a 30 round magazine. It is available at Level 2 to the player, as part of the LMG default class.

The HK21 will kill in 3 shots at any range, or 2 headshots, and has medium recoil. This makes the HK21 extremely powerful at medium range. Long-range encounters can be dealt with by firing single shots. The HK21 has the smallest capacity out of all the LMGs (though on par with the Stoner63), so the round drum attachment is extremely useful, as it doubles the ammunition capacity to 60 rounds. The iron sights, while clear and open, can be difficult to use. For this reason, the Red Dot sight or Reflex Sight is recommended.

The HK21 has a very slow movement speed, so users will benefit greatly from Lightweight. Steady Aim benefits the HK21 greatly as it drastically improves its CQB capabilities. Sleight of Hand is also very useful for this weapon, as it dramatically reduces the amount of time needed to reload, as well as increasing ADS speed with the Pro version.

Attachments

 * Infrared Scope
 * Red Dot Sight
 * Extended Mag
 * ACOG Scope
 * Reflex

Zombies

The HK21 is availible in both zombie maps and the classic zombie pack from the Hardened Edition. It bears similarities to the Browning from World at War as it has low rate of fire, high damage and long reload time.

When upgraded it becomes the H115 Oscilliator.

Trivia

 * The HK21 is based off of the G3 battle rifle.
