Nope, though you could probably say that of Savage also, at least the ones I've handled (never owned one).

Now maybe I've been spoiled somewhat by some of my other rifles, the Sakos and pre 64 model 70 for example, but there's no way the Rugers I have owned come close to being described as glass smooth and that goes double for the one I own right now. It's considerably rougher than anything else I've got.
