Notes: This is a shortened version of the Yugoslavian version of the M-48 above, using a 17.4-inch barrel. It was designed shortly after World War 2 for use by Yugoslavia’s armored vehicle crewmen, and is therefore often called the "Tanker" Mauser. It has some improvements, such as controlled round feed for increased reliability, a positive extractor, a strengthened receiver, and an improved safety.

Many years later (early 2000s), the US company of Mitchell’s Mausers entered into a collaboration with Zastava, the maker of the M-63, to produce the M-63 for the American market. These M-63’s have a box magazine, very light (some would say blond) colored wood stocks, and deeply polished and blued metalwork. They are otherwise identical to standard M-63s. They are somewhat popular in the US, but the sights, graduated from 200-1400 meters, are not suited to American hunting, and many owners replace them. The M-63 is not drilled and tapped as standard, but Mitchell’s Mausers will mount scout-type scope sights upon request. Mitchell’s Mausers (or Zastava, actually) has also recently started chambering the M-63 for more calibers, particularly those which would be attractive to US customers.

Twilight 2000 Notes: None of the Mitchell’s Mausers versions exist in the Twilight 2000 timeline. The standard M-63 equips mostly reserve and partisan units.
