Anyone use Aristocrat ribs?

[fatelvis]

I was thinking about putting together a Relover for silhouettes, and like the idea of the three adjustable sight settings of the Aristocrat rib sight. (The one version with the knob on the side). Does anyone use it, and if so, do you like it? Thanks-

I am not familiar with this product but looked it up on the web. http://www.aristocratproducts.com/page1.html It appears that it cannot be installed without modification to the revolver. (I saw at least 2 screws that would require drilling & tapping the revolver.) If this is correct using this sight would not be Production legal.
