The GIAT ADR (Armes de Défense Rapprochée, lit. "close defense weapon") was a prototype French PDW developed by GIAT Industries.
The ADR is an interesting firearm with two pistol grips. The initial prototypes had two triggers; one trigger for semi-automatic fire and another for fully automatic fire. Ammunition was fed from a 20-round detachable box magazine. The ADR could also hold an extra magazine in the pistol grip. It had cyclic rate of 300 to 1,000 rounds per minute.
A variety of cartridges were tested for the weapon, with various case lengths. Some casings were based on the 5.56×45mm NATO, others on the 9×19mm Parabellum casing necked down, and others with case lengths of 20, 22, 25, and 30mm.
