What are the "Luxe" weapons?

[Deltoiddd]

I want to mod the luxe weapons, but idk what they are or if the mods will affect anything else

The Luxe weapons are basically a duplicate model of whatever weapon has said luxe model.
Good example is I replaced the Luxe version of the Assault Rifle with a AKM rifle and I can still have the normal Assault Rifle.
