Abstract: A low-profile illumination and laser sighting device is provided for sighting a weapon. The illumination and laser sighting device of the present invention includes a single compartment housing and a receptacle placed at one end of the housing. At least one laser is fixed to a support member adjustably coupled to the receptacle and an illumination lamp is coupled to the receptacle in an offset position over the laser. The illumination lamp includes an aperture placed through a reflector wall to allow passage of a laser beam or beams from the laser or from more than one laser. Accordingly, the laser beams and illumination from the lamp pass through a single lens at the forward end of the device. The lasers as well as illumination lamp are thereby self-contained within a single housing and can be easily sealed against outside gas, liquid or solid material. Adjustment mechanism remains primarily inside the device and thereby protected against the outside environment or objects striking the mechanism.
