Many South American countries purchased the vz. 24 rifle in various calibers. Between 1928 and 1938, the Bolivian Army purchased 101,000 vz. 24 rifles, which were chambered in 7.65×53mm Argentine. These rifles were used against Paraguay during the Chaco War in the 1930s, and many of them were captured by the Paraguayan Army, which in turn used them against Bolivia. Colombia ordered 10,000 rifles between 1929 and 1937 and Venezuela purchased an unknown number of rifles in 1930; both countries' rifles were chambered in 7 mm. In 1932, Brazilian revolutionaries ordered 15,000 rifles, which were built with bent bolt handles. Peru ordered 5,000 rifles chambered in 7 mm in 1934, and Ecuador purchased 30,000 rifles in 7.92 mm in 1936. Guatemala and El Salvador ordered 4,000 and 300 7.92 mm rifles in 1937, respectively, and Nicaragua purchased 1,000 7 mm rifles that year. Also in 1937, Uruguay ordered 6,000 rifles in 7 mm, of which 2,000 were vz. 32/Modelo 1932 variants, which were essentially lightened vz. 24s.
