I prefer a peep sight on some of my rifles, like my Marlin .357. So buying a gun like that with a scope on it would not make sense to me, and if I did bid on one I would certainly not offer the full or near full value of the scope in addition to the value of the rifle. I would not pay much at all for an unwanted used scope, even a quality one.

Plus I have several scopes in my stock and like what I have.

I would think people who buy a rifle are looking for the rifle first and foremost, and if it has a scope that is fine, but they are not looking for a scope with a rifle attached.

So I would separate the two to sell them. In fact when I sold my Ruger Super Red Hawk in .44 Magnum I removed the Leopold pistol scope and sold them separately. I would do the same with any expensive scope, but not with a really inexpensive scope.
