The FAMAS can use a variety of rifle grenades up to {{convert|500|g|abbr=on}}. Notable examples include the antipersonnel [[APAV40]] and the anti-tank [[AC58]].

The FAMAS features two [[alidade]]s for aiming rifle grenades with several modes:
* direct fire at {{convert|75|to|100|m|abbr=on}}, in anti-vehicle role
* indirect fire, in anti-personnel role:
** with the FAMAS inclined by 45°, allowing fire from {{convert|120|to|340|m|abbr=on}}
** with the FAMAS inclined by 75°, allowing fire from {{convert|60|to|170|m|abbr=on}}
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.

The FAMAS can also accommodate an external grenade launcher as an add-on module under the hand guard; the US [[M203 grenade launcher]] is sometimes used.
