Action

The FAMAS assault rifle is a bullpup configuration, with the ammunition feed behind the trigger. The receiver housing is made of a special steel alloy, and the rifle furniture is made of fiberglass. The rifle uses a lever-delayed blowback action, an action used on the AA-52 machine gun derived from the prototypes built during Army Technical Department tests having taken place between the First and Second World Wars.

Ergonomics

Fire mode is controlled by a selector within the trigger guard, with three settings: safe (central position), single shot (to the right), and automatic fire (to the left). Automatic fire can be in three-shot bursts (rafale) or fully automatic; this is determined by another selector, located under the housing and behind the magazine.

The FAMAS G2 weighs 3.8 kg (8.38 lb). The G1 and G2 have a large, grip-length trigger-guard like a Steyr AUG to allow easy access to the trigger when wearing gloves.

Both F1 and G2 models of the FAMAS feature a bipod attached to the upper hand-guard.

The FAMAS-G2 and some F1 sport a "polyvalent hand-guard" which features a standard NATO accessory rail, allowing a variety of sights to be mounted, notably red dot sights and night vision units.

The FAMAS features two alidades for aiming rifle grenades with several modes:

  • direct fire at 75 or 100 metres, in anti-vehicle role
  • indirect fire, in anti-personnel role:
    • with the FAMAS inclined by 45°, allowing fire from 120 to 340 metres
    • with the FAMAS inclined by 74°, allowing fire from 60 to 170 metres

In indirect fire mode the grenade support(more exactly named "grenade enforcement ring" in French) is moved forwards or backwards on the barrel which has markings (12/13?). This changes the position of the grenade on the barrel and automatically the volume of the chamber in which the gas expands to push the grenade forward. Each position of the grenade support has a number which is multiplied by a certain fixed number depending on the alidade position, 45° or 75°; this will accurately indicate the firing distance of the grenade.

Ammunition

The FAMAS F1 and G1, the original variants, were designed to use French-made 25-round magazines with 5.56x45mm cartridges. Due to the 1/12 rifling of the F1 barrel and its blowback action, ammunition must be a steel-case, French-made SS109 cartridge; using standard brass-case 5.56x45mm NATO causes overpressure and can cause malfunction. The barrel of the G2 uses a 1/9 rifling, which enables it to use the SS109 or the M193 interchangeably.

During training with blank ammunition, a plug is added to the muzzle of the FAMAS. This plug is necessary for automatic or semi-automatic operation, which it allows by blocking part of the gas.

The FAMAS can use a variety of rifle grenades up to 500 grammes. Notable examples are the antipersonal APAV40 and the antitank AC58. It can also fire some hand grenades designed for this alternative purpose, notably the F2 grenade that includes a bullet trap. The FAMAS can accommodate an external grenade launcher as an add-on module under the hand guard; the US M203 grenade launcher is sometimes used.
