Because Enfields are badass, and rails like that only look at home on ArmaLites/lookalikes and G3/G33 anyways. If it were just one rail on top, IMO I think it would look much better...what the hell are you going to put on that shotgun that needs that much space? It already has a light located in the pump and a laser unit on the side of the pump. Unless you indend to put grenade launchers encircling the whoe thing, there's no point. The top rail is understandable though, because reflex sights are excellent for CQB.
