The KK 62's receiver is machined from steel, and a tubular metal buttstock houses the recoil spring.

A substantial vertical bar in front of the trigger is used for pulling the trigger/handgrip assembly and bolt back when loading.

The KK 62 is fed from the right-hand side, from 100-round belts that are carried in pouches that clamp onto the receiver wall.

The KK 62 has no quick-change barrel, which is a serious drawback when sustained firepower is required; the original usage doctrine was based on agile hit-and-run tactics rather than suppressive fire from a strong position.

The major drawbacks are the lack of a quick-change barrel and sensitivity to dirt and humidity—the KK 62 requires much more care in a combat environment than most FDF assault rifles.
