Joseph Manton who invented the raised rib felt it served a very definite purpose. Churchill felt one never looked at it.

I am of the opinion that any good shot given a gun with stock dimensions that fit, could shoot the gun well with any rib. The style of rib seems to be more for aesthetics than anything else.

However the rib should always taper to end flush with the barrels. When a rib on a side-by-side is above the muzzle of the gun or the height of the bead is changed the pitch is thrown off. The eyes see the top of that bead subconsciously.

I didn't believe it myself but I proved it by lowering a bead on a gun that I couldn't hit with, and it worked immediately.

Like most of you I don't think anyone consciously looks at the rib.
However ,the best shot I ever knew used to put white tape down the rib of his barrel when he got into a shoot-off that went into darkness. He seldom lost.
