A firearm accessory is rotatable on two axes through the use of a sleeve mounted on a bearing comprising of a first part and a second part the second part being rotatable and coupled to the first part facilitating a central opening and a first rotational motion and protrusions with at least one hinge from the sleeve attaching to a mirror device acting as a second rotational motion. An alternative teaches digital control of a swinging mirror assembly having spring acting ball actuators providing the digital action between the actuators and a surface. In another alternative, two armatures also are taught that connect a reflective device to a bearing mounted sleeve in front of or behind a target viewing device. Any of these may be directly rail mounted with appropriate attachment devices or directly connected to or manufactured as an integral part of a reflex sight, night vision, scope or similar viewing system of a firearm.
