microslick in bore?

I saw an ad for the Nosler 48 rifle. It said that they are using microslick on the internal parts and cerakote on the exterior metal. Is Nosler using microslick on the bore or just the action and bolt and trigger? If they are using it in the bore what success are they finding? I am considering having this treatment done to one of my rifle bores (a used 300 Win Mag bore) and wonder if it might extend the life of that bore as well as make cleaning easier. Thanks, Bruin.
