The Fabrique Nationale Model 1949 (often referred to as the FN-49, SAFN, or AFN (automatic rifle version) is an autoloading battle rifle designed by Belgian small arms designer Dieudonné Saive in 1947. It was adopted by the militaries of Argentina, Belgium, the Belgian Congo, Brazil, Colombia, Egypt, Indonesia, Luxembourg, and Venezuela. The selective fire version produced for Belgium was known as the AFN.
While well regarded for its high build quality and reliability in comparison to the rifles of the time, its marketability was limited, as it was not developed in time for use in World War II but later, as many militaries had already begun the switch to selective fire battle rifles. About half of FN-49s were produced as selective fire automatic rifles, but the small 10 round box magazine limited the usefulness of the fully automatic feature.
