I believe it is called Target grey..you can get that finish on a standard ruger by bead blasting it with an aluminum oxide beads. COmpany in Wyoming by the name of Cheyenne Blue I believe does this. YOu can buy a Leupold scope with the Gun metal blue finish and it may be close. Another option is to get the gun cerrakoted by fit4duty ..they have some beautiful shades that could match up with pretty much any scope/ring combo.
