Editing Krag–Jørgensen (section)

=== Modified to self loaders ===
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.

==== Sunngaard's automatic rifle ====
In 1915 Sergeant Sunngaard proposed a design for making the Krag–Jørgensen into a selfloading rifle. The design was considered over a period of time before it was declared to be 'quite without value', primarily because the requisite pressure would not be attainable without major redesign of the rifle.<ref name="NMG-21" /> For this reason, no prototype was made.

==== Self-loading device SNABB 38 ====
In 1938 a Swedish design called the SNABB was considered. This was a modification that could be made to virtually any bolt-action rifle allowing it to be converted into a self-loading weapon, therefore presenting a chance to cut costs as compared to manufacturing new weapons.<ref name="NMG-21" /> The device used gas pressure to operate the bolt handle with the help of a runner. The modification was deemed by some to be unnecessarily complicated.<ref name="NMG-21" /> A separate pistolgrip was needed, and the receiver needed major modifications.<ref name="NMG-21" />

A prototype was manufactured in the autumn of 1938 and tested for several months. While moderately successful, the modification would cost about three times as much as originally thought, and the project was dropped due to lack of funds.<ref name="NMG-21" />
