The FAMAS (Fusil d'Assaut de la Manufacture d'Armes de St-Etienne, meaning "Assault Rifle from the St-Etienne weapons factory"), nicknamed le Clairon, is a bullpup select-fire assault rifle chambered in 5.56×45mm NATO. It was developed by GIAT Industries in France.
The first model, the FAMAS F1, was manufactured in 1975. These guns had proprietary 25-round magazines, a one-finger trigger guard, and other minor differences from the current FAMAS G2 model. Production of both models was discontinued in 2000.
Later, the FAMAS rifles were redesigned for better integration with NATO standards, culminating in the "G1" and "G2" models. The G1 was an intermediary model; it was able to accept both the proprietary magazines and STANAG magazines. The latest configuration (circa 1994), the G2, accepts only STANAG magazines.
The main selector switch has three positions - safe, semi-automatic and full auto. There is an additional selector switch behind the magazine; when the rifle is set to full-auto, this selector switch has two settings - full auto, and three-round burst.
The rifling in the bore has three grooves instead of the more common 4-6. The F1 models utilize a 1:12 rifling twist; the G2 models, a 1:9 twist.
The FAMAS rifles have Picatinny rails and are able to mount under-barrel accessories, such as grenade launchers and shotguns. All rifles are shipped with sling and bayonet. Most also come with integrated bipods (aside from the SMG configuration).
- The FAMAS F1 is featured in Call of Duty: Modern Warfare 2. The F1 Valorisé is featured in Call of Duty: Black Ops even though its appearance is anachronistic for the 1960s setting. A fictional futuristic F1 Valorisé also appears in Call of Duty: Black Ops III as the "FFAR".
