As one who has done an awful lot of this type of job for the various importers over the years, I can assure you that the job is both minor and routine. Probably only about 15 minutes of work. Ruger, like most production rifles are assembled, test-fired and packed by semi-skilled workers. Such minor teething problems are not uncommon in all brands and are easily rectified with some minor adjustment. The basic design is good, just a bit of fitting required.
