Abstract: A device for aligning a telescopic sight includes two opposing reference cards connected to each other within a common plane by a connecting bar and a level indicator on a surface of at least one card. The alignment device is attached to the front or rear scope base of a firearm, so that the front surfaces of two opposing reference cards appear on either side of the reticle. Once the alignment device is secured to the scope base of the firearm, the reticle may be aligned with the bore axis by rotating the telescopic sight until the horizontal cross hair is parallel with any corresponding pair of reference lines of the reference cards. The alignment device can also include an adapter that allows the alignment device to be mounted to a firearm by coupling to a corresponding slot of a mounting platform.
