The Infanteriegewehr Modell 1842 () was one of the first standardised service rifles used by the Swiss armed forces. It was introduced in 1842 as a result of a decision by the authorities of the Old Swiss Confederacy to standardise the weapons of the then still separate armies of the Swiss Cantons.
Milbank-Amsler conversion
The weapon's barrel was rifled in 1859 (T.59) and then modernized again in 1867 (T.67) with a Milbank-Amsler receiver system to convert it to a breech loader. This variant was used by the Boers during the Boer Wars.
