Looks like I'll pass on the S&K mount.   Unfortunately, the Kraghaus is not available for the Norwegian. Is there a drill and tap mount available?  I thought that since Williams discontinued the adapter plate for the Norwegian none were available.  Drilling and tapping is not a big issue since the stock has been cut and refinished and the barrel shortened.  I may just go with a Williams FP sight if scoping is impractical.  I just don"t do that well with open sights any more.  Thanks for the answers.
