As I understand it or, least what has been told to me, installing claw mounts on a double rifle involves stripping off the top rib, fitting the mounts to match the countours of the barrels , regulating and silver soldering in place and then cutting/refitting the rib and reblueing. All pretty much straight forward in my mind but I have a question about the regulation part. I am assuming that this means to make the mounts exactly centered but am not sure. Has any one hee ever done this or had it done? Thanks for any comments.
