Throughout the late 1920s and into the 1930s, Czechoslovakia exported hundreds of thousands of vz. 24 rifles to various countries across the globe, with variants chambered in the original 7.92×57mm Mauser, 7×57mm Mauser, and 7.65×53mm Argentine. These included contracts for several South American countries, most of which were 7 mm or 7.65 mm guns. Around 40,000 rifles were sent to Spanish Republican forces during the Spanish Civil War. Nearly 200,000 rifles were purchased by China, seeing action in the Second Sino-Japanese War, which became part of World War II. Iran purchased vz. 24 rifles, along with two other variants, through the late 1920s and 1930s, and later produced their own copies in the late 1940s.
