G&H doesn't fit too many mounts these days but they still have the jigs from decades ago and they do it right. They machine and polish over the screws and pins and reblue the entire receiver and mount base to match. It isn't worth doing to a Savage 110 that is already d&t for a top mount. But if you are attaching a scope to a valuable rifle and want to do it in classic style, do it at G&H. I am in NYC so it is convenient for me to drive to them in NJ and for years I have had any work on a G&H rifle, even the most trifling, done there.
