The Mauser-Vergueiro was a bolt-action rifle designed in 1904 by José Alberto Vergueiro, an infantry officer in the Portuguese Army. It was manufactured by Deutsche Waffen und Munitionsfabriken (DWM). It was based on the Mauser 98 rifle with the introduction of a new bolt system derived from the Gewehr 1888 and Mannlicher-Schönauer. Outside Portugal, the rifle was known as the Portuguese Mauser. It used the 6.5x58mm Vergueiro cartridge, designed specifically for its use. 
The rifle replaced the Kropatschek M/1888 as the standard infantry rifle of the Portuguese Army in 1904. It was replaced my the Mauser 98k in 1939. In Portuguese service the weapon was designated Espingarda 6,5mm n/1904. A scaled-down version of the rifle was classified as a catbine and designated Carabina 6,5 mm m/1904. 100,000 rifles were made for Portugal. An additional 5,000 rifles were chambered with a 7x57mm Mauser and were made in 1905 for Brazil's Federal Police using leftover components from the Portuguese order and distributed in Rio de Janeiro and São Paulo. In 1915, 25,000 Portuguese Mauser-Vergueiro rifles were sold to South Africa, which had insufficiant Lee-Enfield SMLEs to supply all of their troops.
In Portuguese and South African service the Mauser-Vergueiro saw combat service during the East Africa Campaign. German troops in East Africa captured some of these rifles and used them in combat. In 1942, Portuguese forces briefly fought against the Japanese occupation of Portuguese Timor using Mauser-Vergueiro rifles.
The Portuguese modified many of their rifles to chamber the 7.92x57mm Mauser after their switch to the Mauser 98k in 1939. The modified rifles were designated Espingarda 8mm /1904/39.
