The Jarmann M1884 is a Norwegian bolt-action repeating rifle designed in 1878 adopted in 1884.[1] The Jarmann's adoption, and subsequent modifications, turned the Norwegian Army from a fighting force armed with single-shot black-powder weapons into a force armed with modern repeating weapons firing smokeless ammunition. Several thousand were manufactured to equip the Norwegian Armed Forces in the 1880s, and it also saw some, though very limited, use in Sweden. The design is unique, and was the brainchild of Norwegian engineer Jacob Smith Jarmann. After the design had been phased out of the Norwegian Army, a number of the weapons were rebuilt as harpoon guns.
