This is a MG74 with Aimpoint M4H, Aimpoint Magnifier and a TLLM (light/laser infrared module), mounted on the left side.
This setup was used as the front gun of the passenger seat of the “Sandviper”. The Sandviper is a modified Puch G (Mercedes-Benz G-Class), that was used by the Jagdkommando (Austrian Army special forces) during the Chad mission. The car is also equipped with a M2 .50 BMG on top with a Aimpoint MPS3 and an JT LMT 700 tactical light.
Many thanks to Gregor for sharing these photos with us.
