Here is the letter from the BATFE:
Sorta spells it out but sorta still leaves questions.
NFA don't care about it because it is not and never was a shotgun, it's not a pistol or revolver, the AG excluded shotgun shells from the DD category and I guess they don't consider it concealable so it doesn't fit the AOW category either.
So, from the NFA viewpoint it's less of a firearm than a threaded extra wide drinking straw ... bat s--t crazy people running that place.
It's not a "shotgun" or a DD under GCA for the same reasons but if GCA didn't have a looser definition for the generic "firearm" it wouldn't even be a firearm under GCA.
It's the concealable part that makes me scratch my head since it's concealable down a pant leg or with a big enough coat. But with a big enough coat I guess a Barret is concealable. So maybe they have some minimum dress code bar like it has to be concealable on a guy wearing flip-flops, gym shorts and a wife beater.
The >26" length matters to the NFA for a "shotgun" but this was never a "shotgun" so it's not a weapon made from a shotgun and so I don't know why Mossberg went through extra effort to make it 26.X" and not let it be shorter. Maybe they left it over 26" because of the "otherwise" in 18 USC 921 (a)(6) which seems overly cautious since it still says "made from a shotgun".
