Gun fit for scope mounted rifles, that is comb height, depends on scope height. It is rarely addressed with the care that shotgun fit is. Most rifle combs are too low for quick mounting and shooting. A good test is to close your eyes, quickly mount your rifle, "checking" it just as you would a shotgun, and then open your shooting eye, or eyes. If you are not looking directly into the scope with the cross hairs clearly visible, the rifle does not fit. Most do not. Jack O'Connor discusses this at some length, I believe in the "Hunting Rifle".
