I don't know what the hole mounting pattern for the Razor looks like, and I don't know if it interferes with internal components on the slide...
That being said, if the above checks out, the cut and d&T should be fairly straight forward for any GS/machinist. I made a riser block for a Burris Fastfire 3 to fit an ADM picatinny mount in a couple hours from a piece of scrap 6061 on a Bridgeport mill. Even matched the front/rear profile radius.
