They don't have a website, but call them at 248-628-1811.
Call them and ask for a quote. FWIW they can also do sights for the M1A and Benelli, but both were expensive, so in other words they can probably put nightsights on anything.
I don't know if they do actual sight-in. If it costs more than Ernest, send it to him, because he put the Trijicon front and plain Novak rear on mine and I know he carries (or used to?) carry the parts.
