The FAMAS rifle is a bit strange looking. However, given it is French and they have their own aesthetic, one should not be surprised. It is still the standard issue rifle of the French Army.
Ian McCollum of Forgotten Weapons has an interesting video on the French Navy variant – the FAMAS G2. It is updated to be able to use 62-grain 5.56×45 NATO ammunition and accept standard NATO magazines. The French Navy has issued these to their Fusiliers Marins and Commandos Marine.
