A collapsible reflective optical sight for a firearm includes a base that mounts the optical sight to the firearm, a lens attached to and rotatable with respect to the base, wherein the lens includes a first optic with a reflective surface and the lens is folded with respect to the base for storage in a collapsed configuration and is angled with respect to the base in a deployed configuration for use in aiming the firearm, a light source on the base that reflects light off the reflective surface of the first optic to a user for use in aiming the firearm, a mechanical sight on the base for use in aiming the firearm when the lens is in the collapsed configuration, and a self-contained locking mechanism to mount the collapsible reflective optical sight to the firearm.

A reticle unit equipped with an optical apparatus such as a riflescope includes: red and green light sources radiating red light and green light; a disc-like shaped reticle substrate that has a diffraction grating formed at substantially the center of a surface having substantially circular shape; and red and green mirror members converge light radiated from the red and green light sources, make incidence on the reticle substrate from corresponding side surface portions of the reticle substrate to illuminate the diffraction grating so as to emit first order diffracted light reflected and diffracted by the diffraction grating along a normal direction of the diffraction grating.

The invention relates to an optical device for displaying a reticle or a target mark in a measuring or sighting telescope, comprising a reticle plate with a reticle disposed on one surface, a light source for illuminating this reticle, and the reticle plate has an entry surface for a beam path disposed to the side of the surface provided with the reticle, and at least one retroreflector is disposed on at least one light exit surface of the reticle plate, and a reflective layer of the retroreflector is directed towards the reticle plate.

A camera system having a sight device, with a housing configurable for securing about a weapon, the camera connects with a smart phone device for displaying an image from the sight device for accurately targeting with a weapon.

A pistol, incudes a slide; a lens attached to and rotatable with respect to the slide; a light source that reflects a light off a reflective surface of the lens to aim the pistol; a hood rotatably mounted and in contact with the lens, wherein the hood folds over the lens in a collapsed configuration and is angled from the lens in a deployed configuration, and the lens, the light source, and the hood fit within an outline profile of the slide in the collapsed configuration.

The present disclosure provides techniques, systems, and devices that support indicating gun state information. One or more electronic components may be used to indicate the gun state information, and the electronic components may be coupled with a gun. The gun may identify a state of the gun based on a compute component including a data signal, and the compute component may be coupled with the gun. The gun may select a representation of the state of the gun, where the representation of the state of the gun is compatible with an electronic component coupled with the gun. The gun may indicate, at the electronic component and based on the compute component, the state of the gun with the representation of the state of the gun. Indicating the state of the gun may include displaying an icon, illuminating the electronic component with a color, or pulsating the electronic component.

A sight mountable or mounted on a device including a rear sight and a front sight each having a sight aiming indicia useful in aiming the device.

A riflescope that stores several grouped ballistics data includes a reticle having individually addressable indicators, a memory that stores two or more stored sets of ballistics data, where each set of ballistics data is mapped to a respective set of indicators of the reticle, a selector configured to choose one of the stored sets of ballistics data as an active set of ballistics data, and a driver structured to energize only those indicators of the plurality of indicators that are mapped to the active set of ballistics data. Methods of selecting an active group of ballistics data are also described.

A gun sight assembly includes a housing with an inner bore and a sleeve. The sleeve has an axial cavity in which a luminescent source may be housed. The sleeve is press-fit into the bore such that complementary engagement features of the bore and the sleeve engage each other to lock the sleeve in place within the bore. In one version, the sleeve can be first received within an adapter configured for press-fit into the bore of the gun sight blank.
