Yes you can. There are rifled tubes for shooting saboted slugs. Use improved cylinder or cylinder to shoot foster style slugs. The question is why would you want to shoot rifled slugs through your over and under?
A front and rear rifle sight or scope are generally required for reasonable hunting accuracy.
