A pivoting accessory mount used for attaching auxiliary devices such as sighting devices to a firearm. The accessory mount includes a base member that attaches to the firearm and includes a mounting support and a shaft. An accessory receiver is pivotally received and retained about the shaft. The accessory receiver is pivotable between an inactive position along the side of the upper receiver of the firearm and an active position extending substantially vertically relative to and in alignment with the upper receiver of the firearm. The mounting shaft is linearly displaceable, thereby engaging the accessory receiver when in the active position to prevent accidental displacement of the accessory receiver.

A firearm laser sight alignment assembly includes a laser module for emitting a beam along an optical axis, the laser module having an outer seat. The alignment assembly encompasses a resilient grommet mechanically engaging the outer seat in a first adhesive free interference fit.

A bow sight automatically corrects and compensates for various dynamically changing aiming, shooting, and / or environmental conditions. The bow sight can perform situation-specific aim evaluations and corrections to correct or compensate for situation-specific shooting and environmental factors, at a given time and on a per-shot basis. The bow sight includes integrated sensor-type devices, such as a range finder, an inclinometer, and an anemometer, which detects values of situation-specific shooting and environmental factors and communicates such detected values with a processor or other control device. The processor uses the situational specific data, as well as bow and arrow performance data, and data from shot calibrations, to calculate precise vertical and horizontal aim compensations required to accurately hit the desired target point. The bow sight displays a new crosshair, dot, or multiple dot set, to direct the archer to a situation-specific aiming point for the most accurate shot under those particular circumstances.

A firearm sighting system includes a rear sight unit having a plurality of separate sight elements adaptable for “zeroing” the same gun with different ammunition. In preferred embodiments, a rear sight unit comprises windage and elevation adjustments for each of two sight elements, so that multiple ammunition types having different trajectories may be fired accurately from a single firearm after zeroing-in one of the plurality of sight elements for each of the different ammunition types. Preferably, the separate sight elements may be connected to each other or to a common pivot arm or movable bracket so that moving one sight element into the sight path automatically removes the other from the line of vision. Elevation adjustments may be done in various ways, for example, by sliding sight elements out along an arm or bracket, or by changing an angle of the arm or bracket relative to the firearm. The preferred sighting system also includes an elevation-adjustable front sight unit, which may act as an extension member for gross adjustment of the front end of the firearm by significantly lowering the barrel position for a given line of sight between the user's eye, the selected rear sight, and the front sight. Alternatively, the rear sight unit multiple sight elements may comprise only one that is windage adjustable and elevation adjustable, which rear sight unit may cooperate with a front sight unit that has one sight element that is windage adjustable and elevation adjustable.

A day / night weapon sight assembly that consists of daytime sight and a nighttime sight allows the use of both sights without change in eye relief even when the nighttime sight is attached to the rear end of the daytime sight. This is achieved by supporting the daytime sight moveably in the direction of the optical axis and by supporting the nighttime sight with the use of a plane-parallel motion mechanism that allows switching of the nighttime sight between the upper inoperative position and the operative position behind and coaxially with the daytime sight.

An apparatus, a kit, and a method of use thereof for assisting snipers or long-range shooters in arriving at a firing solution for adjustment of an aiming system are provided. The apparatus can include a housing including a viewing area and a slide including a matrix of firing solutions printed thereon based on a plurality of density altitude values. The slide is movable with respect to the housing such that a portion of the matrix of firing solutions is viewable in the viewing area of the housing based on a density altitude value. This allows a user to adjust the trajectory compensation of a telescopic sight or any other aiming system by using the current measured density altitude.

For a firearm sighting device with an electrical illumination device that can be turned on and off by means of a switch, the switch is embodied and arranged in or on the sighting device such that, for the conventional attachment of the sighting device on the firearm, the switch is activated mechanically to turn on the illumination device by the activation of an actuator provided in or on the firearm for setting the firearm into the armed state. By disabling the firearm, the switch is activated mechanically to turn off the illumination device. Preferably, the activation of the switch is performed using a non-contact method, for which, in particular, the configuration of the switch as a reed contact is suitable. The switch can also be part of a retrofit kit, by means of which a sighting device for a firearm can be equipped at a later time with the previously mentioned function. Here, the switch of the retrofit kit replaces a standard switch operated by hand separately from the firearm.
