Abstract: A gun sight clamping system utilizes a resilient device and an over-center cam to attach a gun sight to the rail of a gun. The body of the clamping system is clamped to the rail using a clamping mechanism on one side of the assembly and a resilient device on the other side of the assembly. The resilient device operates in a direction parallel to the clamping direction. A cross bar connects the clamping mechanism to the resilient device and provides a means to squeeze the body of the mount to the rail. As the lever is closed, the cam drives the cross bar, pulling the clamping mechanism against the rail. The resilient device allows the cam to move to an over-center position wherein the unit resists loosening during operation. Once the over-center position is achieved, the spring force of the resilient device holds the cam in the closed position.

Abstract: A night sight includes a notched bottom portion, permitting the use of a large objective lens for maximized light gathering capability while also permitting the night sight to be mounted with its center line relatively close to the center line of the barrel of the weapon with which it is used.

Abstract: A rifle scope system allows adjustment of the scope while a shooter maintains the shooting posture and the scope sight picture. The scope system comprises an adjustment system comprising an electromechanical mechanism that responds to a signal from a remote controller manipulated by the shooter without having to significantly disturb the shooting posture. The adjustment system allows the shooter to adjust the scope's point of aim to coincide with a bullet's point of impact at a target. Such adjustment can be performed either by the shooter. Alternatively, such adjustment could be performed by a processor configured to adjust the point of aim based on a ballistic parameter associated with the bullet or the shooting environment. The adjustment system allows such processor-determined adjustments to be effected in a quick manner.

A set of scope reticulate components—cross-hairs and the like—or a scope alignment reference true to those components—is then brought operably into alignment with the aligning cap's reticulate means and the scope and cap together are re-set into alignment with the firearm bore's center or a firearm alignment so as to eliminate a canted disposition between scope and firearm.

Abstract: Disclosed is a riflescope that incorporates physical measurements and user specific firearm parameters to calculate and designate the target impact point. The scope incorporates a laser range finder with the receiver integrated into the visual sight path thus utilizing the large objective aperture to collect as much reflected light as possible. This ensures long distance operation while maintaining a compact form factor. The line-of-sight laser distance and inclination angle are measured and used to calculate the actual horizontal target distance. A user interface keypad and display provide a mechanism to enter in firearm and ammunition specific parameters such as muzzle velocity and ballistic coefficient. A barometric pressure and temperature sensor measure the actual air density; this and the user entered ballistic coefficient quantify the resulting bullet drag and thus resulting final velocity.

Abstract: A device is disclosed which enables a scoped firearm owner to determine whether a scope has lost zero due to being moved or hit. A blank cartridge form is attached to a second scope by a bracket. To use, the rifle is first sighted in, then the blank cartridge form is inserted to the rifle chamber and the device is rotated around the chamber until a stop device protruding from the bracket touches the rifle scope. The rifle is then placed in a firm rest with the crosshairs of the rifle scope centered on a target at a known distance and the second scope then adjusted to indicate the same aiming point. If the owner is later unsure whether the scope has lost zero, a target can be set up at the same distance, the device again mounted to the rifle, and the two scopes viewed to determine whether the same impact point is indicated. If it is not, the rifle scope can then be adjusted to the spot indicated by the device scope.
