A holographic sight comprises a unitary optical component carrier having a plurality of receptacles for receiving optical components. A collimating optic abuts a surface of a first receptacle. A mirror abuts a surface of a second receptacle. A collar is positioned in a third receptacle and a laser diode is positioned within the collar. A first portion of the collar is affixed relative to a first portion of the third receptacle and a second portion of the collar is free to expand and contract relative to the third receptacle. The laser diode is affixed to the collar proximate the second portion and is free to move relative to the third receptacle with expansion and contraction of the second portion. The laser diode, the mirror, and the collimating optic are positioned relative to each other to create an optical path.

An optical targeting device comprised of a support body, an imaging waveguide joined to and in a position relative to the support body, and a light source mounted on the support body. The imaging waveguide is comprised of an input diffractive optic, and an output diffractive optic. The light source is located to direct a targeting light beam to the input diffractive optic of the imaging waveguide. In operation of the optical targeting device, the imaging waveguide simultaneously transmits incoming light from a scene viewable by a user of the device through the light transmissive body, and propagates the targeting light beam from the input diffractive optic laterally through the light transmissive body and directs the targeting light beam outwardly from the output diffractive optic, thereby rendering the targeting light beam as a point of light superimposed within the scene viewable by the user.

Sight systems comprise a sight receiver and a base attachable to and detachable from a sight receiver. A base carries a sighting component, such as an iron sight or optic sight. A sighting component may be attachably and detachably mounted to a base, or a sighting component may be made integrally with a base. A base may carry plural sighting components. Sight systems may include plural interchangeable sight receivers, bases, and/or sighting components. In some embodiments, interfitting structures at least partially restrain or retain a base and a sight receiver in longitudinal and lateral alignment, with such structures being longitudinally oriented. In some embodiments, interfitting structures at least partially restrain or retain a base and a sighting component in longitudinal alignment and lateral alignment, with such structures being longitudinally oriented. Some embodiments provide a fastener operable with a compatible and/or complementary surface, together used to urge interfitting parts together tightly.

To enable a user to quickly adjust power ranges of a scope for firearms, a scope may be provided with a primary sight having a primary sighting line and a secondary sight having a secondary sighting line. The primary sight may include a plurality of optical elements disposed within the first housing and an elevation adjustment mechanism for adjusting a zeroed-in position of the primary sight. To prevent impedance of the secondary sighting line, the elevation adjustment mechanism may be located laterally of the primary sight rather than in the conventional position above the primary sight.

A holster system for receiving and releasably retaining a handgun with or without a reflex sight mounted thereon. The holster body comprises a pair of opposing side wall portions and an upper wall portion. The holster body may define a rear accessory sight opening for receiving the handgun with the reflex sight attached thereto. The holster system may include a first rear sight cover selectively and robustly coupleable to the holster body so as to cover the rear accessory sight opening when a handgun with conventional sights extending upwardly about ⅜ of an inch or less mounted thereto is used in conjunction with the holster system. The holster system may also include a second rear sight cover selectively coupleable to the holster body so as to cover the sight opening when a handgun with a reflex sight mounted thereto is used in conjunction with the holster system.

A diffractive optic reflex sight (DORS) is provided for aiming devices in which a virtual image, such as a reticle, is produced and appears in the distance of a user's view when looking through the reflex sight. A light source illuminates a diffractive optical element (DOE) that includes a modulation pattern that generates a patterned illuminations corresponding with the virtual image. A reflective image combiner then reflects the patterned illumination so that the virtual image appears in the distance of the viewer's view. The DORS optical design system is mechanically and optically stable for precision aiming across a range of environmental conditions and in different use scenarios or applications including use in rapidly changing temperatures, varying light conditions, and a wide range of user proficiencies. The DORS optical design system is a readily manufacturable aiming and sighting device for a wide range of applications from handguns to astronomical telescopes.

A sighting device is configured to be mounted on a firearm and comprises a core unit that includes a source of electrical power; a hood removably secured to the core unit and enclosing a portion of the core unit and at least partially defining a sight window through the hood; and an electrical connection between the core unit and the hood, wherein electrical power is transmitted between the core unit and the hood. The electrical accessory may be one of a solar charging cell; a laser pointer sighting device powered by the core unit; or a laser range-finding device powered by the core unit.

An adapter assembly for mounting an optic on a firearm using nuts mountable on bolts, threaded studs, or threaded posts is provided. The adapter assembly may include a bracket having a bottom section to mount to a firearm assembly, and a top side to receive the optic; wherein the threaded posts are integrally formed on the top side of the bracket, or wherein the bracket includes: pockets arranged to mate with at least part of heads of the bolts or studs, the pockets on a bottom side of the bracket; and through openings to receive shanks of the bolts or a different part of the heads of the bolts, or shanks of the studs. Other embodiments may be disclosed and/or claimed.

Certain aspects of a novel weapon sight system combine a direct view, a visible light video view, and an infrared (IR) video view mode. Each of the view modes may be viewed individually or simultaneously with one or more of the other view modes through a single viewing aperture. Further, the one or more view-modes may be provided while providing a bore-sighted reticle superimposed on the selected view. Further, the reticle may be powered separately from the video view electronics enabling use of the reticle regardless of the power status video view electronics.
