The Milkor AV-140 MSGL appears in the campaign and Special Operations as the “REV G-80”, firing high-explosive grenades only. As with its Modern Warfare counterpart, it reloads through the use of a fictional grenade launcher speedloader, regardless of how many grenades were shot prior to reloading. Its designation refers to its revolver-type design and its original design date before its actual development for the SADF, which is 1980.
The AV-140 MSGL is given to Garrick in “Violence and Timing,” and some MSGLs can be found in the watchtower at the end of the “Prison Break” mission.
