The construction was based on the design of the successful PKM machine gun that was previously produced under licence in Poland.

The non-disintegrating closed-link metallic belt type used in the PKM machine gun is a pull-out design, which extracts the rimmed 7.62×54mmR rounds by pulling them rearward out of the link.

The upgraded GPMG will be equipped with a new folding and telescopic buttstock with a cheekpiece and additional grip/pod, the integrated Picatinny rail with iron sight and 3-rail forehand attached to the gas tube, a new grip, a new cocking handle, a new safety switch selector, a new 440-mm barrel (as an option) plus some additional internal changes.

The Polish Army is interested in this machine gun fed from the 100-round soft ammo bag instead of a steel box.

Because of external similarity to the Russian PKM GPMG chambered to the 7.62×54mmR some elements like a buttstock, a grip or a handguard with rails will be able to be used with the Kalashnikov design.
