The Zastava M48 is a post World War II Yugoslavian version of the Belgian Fabrique Nationale designed Mauser Model 1924 short rifle which was produced under contract by the "Kingdom of Yugoslavia" beginning in 1928 and ending with the Nazi occupation in 1941. After World War II, the Yugoslavs took this design and incorporated modifications based upon Germany's Mauser Karabiner 98k. Although similar in general appearance to that of the German rifle, many of the parts of these two rifles are not interchangeable, especially the bolt and related action parts. The main difference between the M48 and the K98k is that the M48 uses an intermediate-length receiver. They are usually easily identified by the top handguard, which extends behind the rear sight and ends just in front of the receiver rin
