An alignment device for telescopic sight mounts ( 101 ) utilizes a front alignment portion ( 103 ) and a rear alignment portion ( 105 ) installed on a firearm 405 . A front bushing ( 109 ), clamped in a front mount assembly ( 401 ) of the firearm provides a precision sliding fit with a front alignment rod ( 107 ). A rear bushing ( 113 ), clamped in a rear mount assembly ( 403 ) of the firearm provides a precision sliding fit with a rear alignment rod ( 107 ). Acceptable alignment of the front and rear mount assemblies is indicated by full engagement of a male indicator portion ( 115 ) of the front alignment rod and a female indicator portion ( 117 ) of the rear alignment rod when the respective rods are slideably engaged. A bore sight engagement element ( 151 ) allows bore sighting of the mounts with the rifle bore ( 425 ).
