Was available, but isn't anymore.  In the way of scope mounting that is.  I only see the Rice sight upon occasion, where that fellow on castboolits found his I can't say.  The Pacific can be made to fit, but requires some work with a file, and maybe an extension to the shaft.  I'm not letting go of the one I modified to fit my .243 Norwegian!

Looking at it anew, I don't know how that fellow got a Rice to work on a Norwegian!  If you got it on there, the screw that holds the safety captive is in the way of adjustment!  The bolt sleeve of the Norwegian is wider at that point too, limiting windage adjustment.  So don't buy one right away cause I said it'd work!
