A quote from the Brownell's site for the Gib lock knob from the link Tim provided: "SPECS: Aluminum, black, anodized. Steel screws. This may require fitting by grinding the tip of the threads to fit some sights." It seems to me that they are aware that the shank is too long for some of the Foolproof sights and you need to grind it down shorter. Just a thought.
