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.[1] The SS-77 was developed to replace the FN MAG. It was designed in 1977 by Richard Joseph Smith and Lazlo Soregi, hence the name "SS-77". "SS" for Smith and Soregi, "77" for 1977, the year it was designed.[1]

Denel unveiled at the Africa Aerospace and Defence (AAD) 2016 exhibit that they'll be replaced in production by the DMG-5 and DMG-5 CX GPMG.[2]

SS-77s typically feed ammunition using an R1M1 disintegrating link belt, though M13 disintegrating link belts and non-disintegrating DM1 belts are also compatible. The belt may also be further contained in a dust-proof nylon pouch with a 100-round capacity, or a waterproof and rigid box with a 200-round capacity.


In the early 1990s, a light machine gun version, the Mini-SS, chambered in 5.56×45mm NATO was introduced. LIW also manufactured kits to convert existing SS-77 to the Mini-SS. Changes include the weight decrease from 9.6 to 8.26 kg (21 lb 3 oz to 18 lb 3 oz) with a folding bipod and fixed butt.[3]
