Jarmann-geværet ble approbert
H.K.H. Kronprinsen bestemte at Jarmann-geværet med fast magasin skulle antas for bruk i det norske infanteriet. Det skulle derimot gå lang tid før modellgeværene ble approbert, dette skjedde ikke før 8. april 1884.

Jarmanns gevær var opprinnelig et enkeltskuddsgevær, og dette geværet ble utlevert til tropper for utprøving allerede fra 1878. Modellbetegnelsene som vanligvis blir brukt kan virke noe forvirrende. Jarmanngeværet med fast rørmagasin under forskjeftet ble egentlig approbert i 1881, men det var først med en approbasjon i 1884 at det formelle grunnlaget for geværets modellbetegnelse ble lagt. Den første modellen kalles derfor M/1884. M/1884 ble forbedret av en approbasjon i 1887 der ca. 15 mindre endringer ble gjort på geværet, og det kan derfor være grunnlag for en M/1887. Andre mindre endringer ble approbert i 1888, 1889 og 1890.

Geværet kan brukes både som enkeltskudds- og repetergevær. Bruksmåten kan reguleres ved hjelp av en omstiller på låskassens venstre side. Flerskuddsmekanismen fungerer på følgende måte: en spiralfjær sørger for å dytte patronene bakover i rørmagasinet. Når sluttstykket føres i bakre stilling trekkes den skutte patronen ut av kammeret og kastes ut. På samme tid senkes patronheisen, og en ny patron presses ut på heisen. Når sluttstykket føres fremover heises patronen opp og når støtbunnen treffer patronen i bakkant føres patronen inn i kammeret.

Kammerlader

Model 1860 Army kammerlader, converted to metallic cartridge after Lund's system some time after 1867.

The 18 bore kammerlader rifles were continuously improved from the time the first model was adopted in 1842. In 1860 a new model was adopted. This model had several radical changes: The most important being the reduction of the calibre from 18 bore to 4''' (linjer, an old Norwegian measuring unit). Since roundballs were no longer used it served no purpose to designate the calibre in bullets per pound. 4''' equals 11.77 mm, and compared to the 18 bore rifles the calibre was reduced with 5 mm. The internals of the barrel were also changed. While the 18 bore kammerlader rifles had Krupp rifling the Model 1860 had hexagonal Whithworth rilfing. Another new feature was rifled chambers. The 4''' kammerlader is a lighter and slender firearm compared to the old models.

Both civilian and military 4''' kammerlader rifles. Civilian kammerlader rifles for the shooting societies were made from parts that were intended for the military rifles. The shooting society kammerlader rifles are distinguished by the steel buttplate and barrel bands. The Army versions had brass bands and buttplate.

Kammerlader

Model 1860/67 Naval kammerlader
Landmark conversion.

The new kammerlader rifles had a short active service, and were soon converted to fire metallic cartridges. When the metallic cartridge was adopted along with the Remington rolling block rifle in 1867, most of the Model 1860 kammerlader rifles were converted to the new calibre. Two conversion systems were used. The Army used the system of Jacob Lund and the Navy relied on the system of Jens Landmark. The conversions are called Lund's rifles and Landmark's rifles. The new calibre was decided to be 12.17 mm, and the new cartridge got the official designation '12 mm Remington' (also known as 12.17x44, 12x42, 12.17x42, 12.7x44 and similar). You can read more about this cartridge in the article about the Remington rolling block.

The following 4''' models are known:

  • M/1860 4''' Army three bander (long)
  • M/1860 4''' Army two bander (short)
  • M/1860 4''' three bander (long) for shooting societies
  • M/1860 4''' two bander (short) for shooting societies
  • M/1860 4''' Navy two bander

rimfire breech block.

Today it is extremely rare to find an unconverted 4''' kammerlader rifle. If you find one, it is probably one of the shooting society models. The 4''' kammerlader rifles were very accurate in it time, and they performed very well in a comparativ shooting competition in Belgium in 1861.

Bayonets

The short Model 1860 kammerlader rifles were equipped with yataghan style sabre bayonets similar to that of the Remington rifle. It was also basically similar to the 18 bore short rifle bayonet. The long rifles was fitted with a socket bayonet.
