Abstract: The front and rear sights for shotguns which are the object of the present invention provide the use of M16/M4 style sights within sight bases which can be affixed to the receiver and barrel of a shotgun. An enhanced level of precision as well as familiarity is imparted to shotguns which employ sights of the configuration described within the present invention. The addition of a M-1913 style rail base to the rear sight assembly brings the added benefit of the ability to add an additional sighting collimator to the rear sight assembly in terms of a reflex, or refractory optical sight which conveys the benefit of a co-witnessed sight alignment. The use of M16/M4 style sights which have proved the test of time in military deployments from the 1960's until the present time bring an operationally sound modality to shotguns that are tactically employed.
