Current version of the FAMAS rifle, standard rifle for the French Navy (the French Army still uses the FAMAS F1 as the their main service rifle). The G1 (which never saw widespread production) can be distinguished by its enlarged trigger-guard, an improved foregrip, but uses the original F1 magazine well and straight 25-round magazines, while the production G2 utilizes the G1's improved trigger guard and foregrip, It has a redesigned magazine well for the use of NATO STANAG magazines.
The FAMAS FÉLIN is a variant of the FAMAS outfitted to be used in conjunction with the FÉLIN combat system. The most notable difference is the replacement of the integral carry handle with a lower profile scope mount for mounting optics, which when used as part of the FÉLIN system would mount a large day/night/thermal video sight capable of transmitting the feed to the soldier's helmet mounted eyepiece. The final production version of the FÉLIN features a forward vertical grip which houses the controls for the system, and has lengthened and bent bipod legs.
Also intended for use alongside the FAMAS FÉLIN is the FAMAS Valorisé (meaning "upgraded"). This variant was intended for use in FÉLIN equipped units for use by soldiers not requiring the actual full FÉLIN combat system. As such, this variant has the same low profile sight rail and new bipod, but omits the second grip and was intended to be fitted with a 4x optical day sight as standard. In the past variants of the FAMAS with a low profile scope rail have been referred to as the FAMAS Surbaissé (meaning "lowered" in reference to the scope mount), however promotional material from the manufacturer GIAT states that the FAMAS Surbaissé is the core weapon (or possibly just component) on which the FÉLIN and Valorisé rifle variants are based.
