Le Fusil Terribles

The Le Fusil Terribles is a unique weapon in Fallout 4. It has the 'Violent' weapon prefix.

Characteristics
+25% damage and limb damage, but has more recoil.

Variants
Combat Rifle

Locations
Found on top of a yellow lootable wooden crate, just as you enter the captain's cabin in Libertalia. The lootable wooden crate is straight ahead from the entrance, next to a lit lantern. It's also found during the Synth Retention quest (during The Institute quest-line), immediately after the cut-scene with X6-88.

Behind the scenes
The name of the weapon appears to be a rough translation from Fallout 3's unique combat shotgun, The Terrible Shotgun, although the name directly translates to "The Terrible rifle" while shotgun would really translate to "fusil de chasse". In any event, the name is spelled incorrectly : "terribles" is in the plural, while the noun and the determiner are in the singular. The 'Fusil' is pronounced as 'Fusi' in French.
