Starting in 1942, remaining PzB 39 rifles were rebuilt with a shortened barrel (590 mm) and an affixed Schiessbecher ("firing cup") attachment threaded to the barrel and used to launch standard rifle grenades.
The cup was the standard type used with the ubiquitous Kar 98k infantry rifle and the ammunition was also interchangeable; there were three types of grenades: an anti-personnel grenade, a light anti-tank grenade and a large-diameter anti-tank grenade.
The grenades were propelled by a special cartridge with a wood bullet.
The rifle was also outfitted with a special sighting arrangement for firing up to 150 m and the wooden forend was removed.
These converted rifles received the designation Granatbüchse Modell 39 (GrB 39) and remained in use until the end of the war.
