Are there any schematics for legendary tech shotguns?

[kdubya]

Also is there an iconic version of the tech shotgun available?

Do any mods add them in?

In the base game, there is no iconic version of DB-2 Satara.
(And I don't really remember if you can buy a legendary version of this shotgun in a shop, but I don't think so)
I don't know if there is a mod to add it
