A gun scope is provided having a battery compartment. The battery compartment may be configured to house one or more batteries to provide electronic power to one or more electronic components associated with the gun scope. The battery compartment is associated with a rotatable component, such as a magnifying ring, and configured to rotate with the rotatable component about an axis. In one embodiment, the battery component may be integrally formed with the rotatable component. In another embodiment, the battery component may be formed as a separate component and coupled with the rotatable component. The battery compartment extends radially outward from the rotatable component and provides a lever for rotation of the rotatable component about its axis of rotation.
