Krag-Petersson
The Krag-Petersson rifle was the first repeating rifle adopted by the armed forces of Norway and one of the first repeating arms used anywhere in the world. Developed by Ole Herman Johannes Krag, the action of the Krag-Petersson was uniquely actuated by an oversized hammer. Another distinguishing feature was that the cartridge rising from the magazine was not seated automatically, but had to be pushed into the breech of the rifle.
