Any other Benelli shotgun that uses a barrel extension like the SBE that is part of the receiver rather than going INTO receiver?

I posted something the other day on another forum that the person was wanting a barrel identified and it had the SBE type barrel extension, Crio barrel markings, longer barrel lug, and was fully rifled so I told them I was 99% sure it was a SBE II slug barrel as I didn't know of any other series that used that type of extension. Do any of you know of any?

I've got M1, M2, M3, M4, Montefeltro, Black Eagle, and Super Black Eagles and I know of those, only the SBE has the barrel extension that makes up the top of the receiver instead of going INTO a full receiver. 

Pic for reference, SBE barrels below, you can see how the barrels make up the top 1/3rd of the receiver once installed:

The others use the style like the M1 below where the extension is a lot smaller and goes into a solid receiver:
