I'm a fan of Leupold 1piece mounts, but if it tickles your fancy, a 1pc pic rail that bridges the ejection port can produce an optic platform that's just as robust as anything else, and it gives more opportunity for ring position to perfectly match your scope design and your eye position along the stock. Depending on the brand of base and rings, you might find that the pic rail + low OR med rings might be the same height as Leup's med rings.

I don't have any particular aversion to pic rails where needed, but I'd honestly rather see a single pic rail on a bolt action hog rifle's forend meant for mounting a kill light than I would an AR covered in rails that aren't getting used. Using pic rails as optic mounts makes sense, so if that's what you're after, do it.
