20 gauge revolving rifle ???

[NUGUN]

The other day I was thinking about how I would love to have a 20 gauge rifle that used a revolver mechanism (as opposed to pump/semi-auto). With a 6-8 round capacity. Would especially like if it were a break-open model.

Were these ever built?

Russian MC255-20, there's a thread about it somewhere on THR, I think...
