It seems FearTheBoomAndBus has vacated the premises. And please tell me you really don’t expect and answer here from the ATF.
I presume by SBS you mean side by side double? It is measured from the breach end of the barrel to the muzzle end. Also check with your local or state LEOs. ATF says 18” I have been told that some states say 20”.
