Looks like he might be a satin or satin cross (the unbroken one). The pics make his fur look really shiny. No underbelly color? So he's a steel...lops are about the most common breeds for making steel colors, but it doesn't look like he has airplane ears, so if he has lop in him, it's a couple generations back.
Probably just your run of the mill crossbred. Looks almost exactly like my first rabbit Chester (although his adoption papers from the humane society called him a brown and black Dutch!)
