The cannon consists of the following main parts: barrel, equipment for taking gases from the barrel, automatic drive, weapon case, weapon lid and feed mechanism

the binding of the movement of the bolt carriers of both cannons of the set is ensured by a toothed pinion, which transfers the movement from the ridge of one carrier to another, the breech is locked when fired, the bolt moves vertically downwards when locked led from the barrel to the gas nozzle, where it acts on the piston, the pulse transmitted to the bolt carrier, which during its backward movement moves the bolt and unlocks the breech, then the cartridge is pulled out and ejected ... cannon, which goes forward, inserts a new charge from the belt into the chamber, locks the breech and fires the charge ...

tensioning of the cannon is done manually on the ground or in flight using a pyrocartridge, the supply is from a steel belt, which seems to fall out of the eye belt to GŠ 23, 30 .... the belt is disintegrating

ammunition: 4 types of ammunition were developed for this set, two training and two combat ...
trainers are marked JNh (TP) - spare and JNhSv (TP-T) spare with stopwatch ..
