A single-mirror target viewing apparatus configured for enabling a gun to be fired at a desired target from a cover position in an aimed manner. The target viewing apparatus comprises a mirror assembly and a mounting base. The mirror assembly includes a single utilized mirror that provides a target imaging surface. The mounting base is configured for being attached to a gun and having the mirror assembly moveably attached thereto. The single utilized mirror is movable between a stowed position and a deployed position and is rotatable between a plurality of rotational positions when in the deployed position. When in the at least one of the rotational positions, the target imaging surface is in a skewed orientation with respect to at least one of a longitudinal axis of a barrel of the gun and an axis that extends generally perpendicular to the longitudinal axis of the gun barrel.
