Are night visions scopes in Fallout 76?

In Fallout 76, I tend to always scrap weapons, not sell, so I can unlock the mods for the respective weapon. Some weapon types, such as the hunting rifle, do not (or very rarely do) provide any further mods to me when scrapped, since I've already scrapped so many.

However, looking through the list of mods available for my hunting rifles, I don't see any night vision scopes. All flavors (short, medium, long) of standard scope, recon scope, etc., are there, but not one night vision scope.

Do night vision scopes exist in the game? If so, how are they unlockable? Are they simply one type of mod that is not learnable by scrapping, but by plan only?

Solution 1:

Are they there, yes.

But only for a few weapons, it seems. They are available in Short, Medium and Long versions for these:

Pipe Weapons

• Pipe Bolt-Action Pistol
• Pipe Pistol
• Pipe Revolver

And for the Alien Blaster (only the Short scope).

There does not appear to be one for Hunting Rifles.
