The Vektor SS-77 is a general purpose machine gun designed by Vektor Arms from South Africa.
In the late 1970s, South Africa was involved in an international controversy over apartheid and the South African Border War in Angola. As a result, it was subject to an international arms embargo and had to, out of necessity, design and manufacture its own weapons. One of the first developments in the field of a South African general purpose machine gun (GPMG) to replace the FN MAG was the SS-77. It was designed in 1977 by Messrs. Col Richard Joseph Smith and Soregi, hence the name "SS-77". "SS" for Smith and Soregi, "77" for 1977, the year it was designed.
In the early 1990s, a version, the Mini SS LMG, chambered in 5.56 x 45 mm NATO was introduced which. Vektor Arms also manufactured kits to convert existing SS-77'ss into the Mini SS. Changes include the weight decrease from 9.6 to 8.26kg with a folding bipod and fixed butt.
