Actually, in this particular case the dovetails are quite within reason. I am not a fan of rifles with the dovetail on the front receiver ring but this one is dovetailed into the barrel. My type S has a barrel of 1.200" just ahead of the receiver ring. That leaves chamber walls at least .375" thick. Subtract about .100" for the dovetail cut and you still have a chamber wall of .275". That's actually a bit thicker than a Military 98 at the same point.
