The KBA-119 is a ukrainian modification of AGS-17.
The AGS-17 is a heavy infantry support weapon designed to operate from a tripod or mounted on an installation or vehicle. The AGS-17 fires 30 mm grenades in either direct or indirect fire to provide suppressive and lethal fire support against soft-skinned or fortified targets.
The weapon uses a blowback mechanism to sustain operation. Rounds are fired through a removable (to reduce barrel stress) rifled barrel.
The standard metal ammunition drum contains 29 linked rounds.The tripod is equipped with fine levelling gear for indirect fire trajectories.
