 The Brazilian Military Police of Rio de Janeiro State used Madsens into the 21st Century.Although some of the Brazilian guns were captured from drug traffickers and pressed into service (mostly old weapons originating from the Argentine Army, as well as some stolen from museums), the majority of the Brazilian police Madsens came from the Brazilian Army; in the 1930s they were commonly used in the wars against banditry in Northeast (bandit groups named cangaceiros); these guns were originally 7x57mm Spanish Mauser weapons re-chambered to fit 7.62 mm NATO.Official sources state that the Brazilian army retired the Madsen machine gun in 1996.
