At the same time that the Hotchkiss heavy machine gun was introduced to the Norwegian Army, some people started considering modifying the Krag–Jørgensen to semi-automatic fire. Doing so would have multiplied the firepower of the infantry, allowing more weight of fire to be brought at a target. Most of the designs put forward were not very well thought out and few of the designers knew enough about firearms to be able to calculate the pressures and dimensions necessary. However, two designs were investigated further, and eventually one prototype was built.
