First produced by Deutsche Waffen und Munitionsfabriken (DWM) and Mauser, they were exported to Uruguay and Brazil.

In this latter country, Brazilian War Material Industry produced upgraded versions until the rifle was replaced by the FN FAL.

The Mosquetão Itajubá M954[7] was a variant fitted with a threaded muzzle, that enabled the use of a flash suppressor or of a grenade launcher.

Its buttplate was inspired by that of the Gewehr 43 (a copy of which was manufactured under the same Itajubá M954 Mosquetão [pt] designation).

This rifle fired the 7.62×51mm NATO cartridge, a grenade launcher was fixed to its barrel and its stock was reinforced with rubber.
