Systems, devices, and methods are provided, wherein a device is attachable to or integrated in a firearm and includes a plurality of sensors that are each configured to sense a respective attribute of the firearm or of an environment surrounding the firearm, and are further configured to provide corresponding signals based on sensing the respective attribute. The systems, devices, and methods may be configured to determine an event from among a plurality of events based on the corresponding signals provided by the plurality of sensors. Systems that include the device may record event data and transmit the event data to various user systems for situational awareness, record keeping, training, and other organizational or legal-process purposes.

A multi-laser bore-sighting riflescope system can receive a first laser beam having a first wavelength and a second laser beam having a second wavelength smaller than the first wavelength. The system can detect reflected light from the first laser beam. The system can calculate an initial range to a target. The system can determine a ballistics solution. The system can find a ballistics aimpoint. Further, the system can illuminate a display of a riflescope display assembly (RDA). The system can mark the ballistics aimpoint with an electronic reticle on the display. The system can redirect the first laser beam to the ballistics aimpoint. The system can redirect the second laser to the ballistics aimpoint. The system can detect secondary reflected laser light from the first laser beam. The system can calculate a secondary range to the target.

The present disclosure describes methods and systems for measuring crosswind speed by optical measurement of laser scintillation. One method includes projecting radiation into a medium, receiving, over time, with a photodetector receiver, a plurality of scintillation patterns of scattered radiation, comparing cumulative a radiation intensity for each received scintillation pattern of the received plurality of scintillation patterns, and measuring a cumulative weighted average cross-movement within the medium using the compared cumulative radiation intensities.

A point of aim shows where a weapon is aimed on a target. An electronic device determines an impact location on the target of a projectile fired from the weapon, determines a distance from the point of aim to the impact location, and moves the point of aim in order to sight the weapon to the target.

A rifle includes a magazine well, a barrel, an exo-bolt, and a rear magazine support. The barrel is detachably coupled to the magazine well. The barrel includes a forward barrel portion on an end of the barrel opposite the magazine well. The exo-bolt is configured to travel along an exterior of the barrel. The rear magazine support is coupled to the magazine well and opposite the barrel. The rear magazine support is configured to come forward toward the barrel and be secured in a plurality of distances from the barrel to adjust a length of the magazine well.

A non-lethal dazzling turret includes a laser operable in the visible spectrum. The non-lethal dazzling turret can be deployed, for example, behind a counter at a convenience store or a gas station, and can include a camera as well as an on-board computer. The non-lethal dazzling turret can stream video to a remote location where an operator can aim and fire the non-lethal dazzling turret at potential targets as needed. Alternatively, a fully autonomous version is disclosed that can be activated by, for example, a panic button.

A rangefinder scope crossbows and other firearms includes an emitter assembly for transmitting radiant energy toward a target, a first collimating lens assembly for receiving and collimating the reflected radiant energy, a prism assembly optically connected to the first collimating lens assembly for receiving the collimated reflected radiant energy, and a receiver assembly in optical communication with the prism assembly for detecting the radiant energy reflected by the target to thereby calculate a distance between the rangefinder scope and the target. A third collimating lens assembly associated with the emitter further increases accuracy of the scope.

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 variable range compensating device, including at least some of a housing having an optical cavity defined at least partially within the housing, wherein the optical cavity extends from an incoming image aperture to an outgoing image aperture; and two or more reflective optical elements, wherein each reflective optical element is adjustably positioned within at least a portion of the optical cavity, and wherein adjustment of at least one of the reflective optical elements adjusts the reflective optical elements such that a target image entering the incoming image aperture is reflected by the reflective optical elements, so as to exit the outgoing image aperture at a determined offset.
