This was intended to be used when soldiers were comfortably firing at distant targets, so it could be quickly turned off in case of an incoming charge or issue to charge the enemy. When flipped down, the cut-off does not allow cartridges in the internal magazine to be fed into the chamber by the advancing bolt. This is a switch on the left rear of the receiver. The rifle had a feature known as a magazne cut-off.
The ammunition of the day did not need dual frontal locking lugs, and the bolt already had three lugs-one in front, one just in front of the bolt handle, and the bolt handle itself-which were considered more than strong enough. For a time after the weapon was adopted by Denmark they experimented with dual frontal locking lugs, but decided against it on grounds of cost and weight. The long extractor, situated on top of the bolt, was inspired by the Jarmann mechanism, while the use of curved surfaces for cocking and ejecting the spent round was probably inspired by the designs from Mauser. They also, over the next several months, combined what they considered the best ideas from other gunsmiths with a number of their own ideas to design a distinct bolt action for their rifle. Krag and Jørgensen therefore decided to convert the magazine into what they referred to as a 'half-capsule', containing only five rounds of ammunition instead of the previous ten. The test performed in Denmark revealed the need to lighten the rifle, as well as the possible benefits of a completely new action. The feedback given by the Danes was vital in the further development of the weapon. One of the early prototypes of the new rifle was sent to Denmark. In 1886, Denmark was on the verge of adopting a new rifle for its armed forces. Early models contained ten rounds and were fitted to modified versions of the Jarmann - though they could be adapted to any bolt action rifle. The principal feature of the capsule magazine was that instead of being a straight box protruding below the stock of the rifle, it wrapped around the bolt action. Together they developed the capsule magazine. Not satisfied with the tubular magazine of the Jarmann rifle and his earlier Krag-Petersson rifle (adopted by the Royal Norwegian Navy in 1876), he enlisted the help of master gunsmith Erik Jørgensen. Ole Krag, captain in the Norwegian Army and director of Kongsberg Våpenfabrikk (the government weapons factory), therefore continued the development of small arms, as he had since at least 1866.
Several nations adopted small calibre repeating bolt action rifles during this decade.Īn exploded view of an early Krag-JørgensenĮven though Norway had adopted the repeating Jarmann rifle in 1884, it was soon clear that it was at best an interim weapon. During this decade smokeless powder came into general use, and the calibre of various service rifles diminished. The 1880s were an interesting period in the development of modern firearms.
Today, the Krag-Jørgensen is a popular rifle among collectors, and is valued by shooters for its smooth action. The next major US rifle also had a magazine-lock off. For others, the magazine's features likely aided adoption. The relative complexity of manufacturing this magazine has been suggested as a reason why many countries did not adopt the Krag-Jørgensen. However, the design was easy to "top off", and unlike most other top-loading magazines, the Krag-Jørgensen's magazine could be topped up without opening the rifle's bolt. While a similar claw type clip would be made that could allow the magazine to be loaded all at once, normal loading was one cartridge at a time. This presented both advantages and disadvantages compared with a top-loading "box" magazine, which were often fed using a " stripper clip". The cartridges were inserted through the side opening, and were pushed up, around, and into the action by a spring follower. While many other rifles of its era used an integral box magazine, the magazine of the Krag-Jørgensen was integral with the receiver (the part of the rifle that houses the operating parts), featuring an opening on the right hand side with a hinged cover. It was adopted as a standard arm by Denmark, the United States and Norway.Ī distinctive feature of the Krag-Jørgensen action was its magazine. The Krag-Jørgensen is a repeating bolt action rifle designed by the Norwegians Ole Herman Johannes Krag and Erik Jørgensen in the late 19th century.
