An adjustable firearm sight includes a body made of a flexible and resilient material. The body includes an elevation arm connected to the body and extending proximally therefrom to a sight portion, where the elevation arm and the body comprise a monolithic structure. A cam body below the elevation arm has a cam surface in contact with a bottom surface of the elevation arm, where the cam body is rotatable to change a vertical position of the sight portion. Also disclosed is a front sight assembly where a sight element is disposed in a longitudinal bore through a sight body. A proximal end of the longitudinal bore has a reduced size. At a distal end, a retention pin is disposed in a retention bore that extends transversely to and intersects the longitudinal bore such that the retention pin occupies the longitudinal bore to retain the sight element.

A sight for a firearm includes a housing, a tritium light source, a light transmission rod, and a retainer. The housing is configured to be mounted to a firearm. The tritium light source is supported within the housing. The light transmission rod is disposed in a cavity of the housing and positioned adjacent the tritium light source. The light transmission rod is configured to collect and transmit both an ambient light and a light from the tritium light source. The retainer is removably engaged with the housing and fixes the light transmission rod within the cavity. Removal of the retainer provides access for replacement of the light transmission rod.

A collapsible sight for a firearm, including a lens attached to and rotatable with respect to the firearm, a light source that reflects a light off a reflective surface of the lens to aim the firearm, a one-piece hood rotatably mounted and in continuous contact with the lens and including an opening in which the light that is reflected off the reflective surface is viewed to aim the firearm, wherein the hood folds over the lens in a collapsed configuration and is angled from the lens in a deployed configuration.

An apparatus includes one or more light emitting diodes (LEDs) configured to be coupled to a power supply and to generate illumination, such as to generate a reticle in an optical scope. The apparatus also includes a first switch coupled in series with the one or more LEDs. The first switch is configured to selectively activate and deactivate the one or more LEDs based on whether the first switch is turned on or off. The apparatus further includes a low power detector configured to sense a low power condition of the power supply and to repeatedly turn the first switch on and off in response to the low power condition to cause the one or more LEDs to blink. The low power detector is configured to turn the first switch on and off at a given rate, and the given rate increases as the power supply is depleted.

A gunsight for aiming a firearm may comprise a display and an eyepiece optic positioned rearward of the display for allowing a user to view the display through the eyepiece optic and a motion sensing module. The eyepiece optic may comprise one or more eyepiece lenses. Circuitry of the gunsight is operatively coupled to the microbolometer and the display. The circuitry may comprise one or more processors and a non-transitory computer readable medium storing one or more instruction sets. In some embodiments, the one or more instruction sets include instructions configured to be executed by the one or more processors to receive a stream of motion signals from the motion sensing module and display an image to the user in response to the stream of motion signals.

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.

A collapsible sight for a firearm, including a lens attached to and rotatable with respect to the firearm, a light source that reflects a light off a reflective surface of the lens to aim the firearm, a one-piece hood rotatably mounted and in continuous contact with the lens and including an opening in which the light that is reflected off the reflective surface is viewed to aim the firearm, wherein the hood folds over the lens in a collapsed configuration and is angled from the lens in a deployed configuration.

A reticle for an aiming device includes a number of holdover indicators on the reticle that may be individually selected; an input for receiving ballistics data; and a processor configured to, based at least in part on the received ballistics data, select one or more of the holdover indicators; and cause the selected holdover indicator or indicators to visibly change state on the reticle. Methods of operating a digital reticle are also described. Further disclosed is a system that includes the reticle above, as well as a rangefinder for providing range data and a ballistics calculator for providing ballistics data.

The present disclosure is directed to a fixed magnification optical aiming device for a firearm including one or more high efficiency illumination sources alone or in combination with one or more lenses and/or other light collection devices to increase reticle illumination efficiency. The optical aiming device may include one or more internal power supplies, one or more external power supplies, and one or more solar cells.

An optical sight includes a housing, an optical element, and a photo detector. The housing has a main body, a pair of upwardly extending posts, and a cross member extending between the pair of upwardly extending post. The optical element is supported by the housing and positioned between the pair of upwardly extending posts and between the main body and the cross member. The photo detector is positioned in the housing and configured to detect ambient light at a target object. A first post of the pair of upwardly extending posts and the cross member are joined at a shoulder of the housing. The photo detector is formed in the shoulder of the housing.
