Since Ruger does not say so, which would be a feather in their cap and partly justify the ever-increasing MSRP, I doubt it.
They now make their own barrels and, judging by reduced bitching about poor results based on over generous throats and rough barrels, they clearly do a better job in final quality control now than before. But there is little evidence that they emphasize hands on finishing that takes time and skills that drive up cost.
The #1 rifle otherwise has had few if any dedicated innovations or fixes since its inception.
