An accessory mounting interface for a firearm, and a related method, are disclosed. The interface has a firearm accessory, a first elongated fastener, and a second fastener rotationally mated to the first elongated fastener. The first elongated fastener has right-handed threading and is arranged through a through hole in the firearm accessory with a first end extending below first and second halves of a first slot protrusion of the firearm accessory. The second fastener has a length greater than a width, the length measured along a longitudinal axis of the second fastener, the second fastener having a plurality of straight edges. At least one of the plurality of straight edges prevents the second fastener from rotating further than a closed position when the at least one of the straight edges abuts a sidewall of an elongated slot in the firearm.

A sight assembly for a firearm includes an optical sight configured for mounting to a firearm. The optical sight includes a sight body retaining a lens and has a point-of-aim indicator visible on the lens. A light source on the sight body is configured to communicate a firearm status to a user, such as whether a round is chambered in a chamber of the firearm. In one example, the sight assembly can be mounted to a handgun or atop a rifle. In some embodiments, the optical sight is configured as a reflex sight.

A method for forming a weapon accessory mounting device to attach to a projectile firing weapon is disclosed. A flexure for receiving a body of the weapon accessory is formed. A pivot portion is formed at a first end of the flexure to attach the flexure to the weapon at a first attachment region. A second attachment portion is formed at a second end of the flexure to attach the flexure to the weapon at a second attachment region. A first aperture is formed in the pivot portion configured to receive a pivot pin. A second aperture in the weapon accessory body receives the pivot pin at a weapon accessory body first end to attach the weapon accessory body first end to the pivot portion. The pivot portion is configured to convert at least a portion of energy of a weapon shock recoil from translational energy to rotational energy.

An adjustable firearm scope mounting assembly includes first and second mounting members, each including a base portion fixable relative to a firearm, and an upper portion configured to support a respective scope portion. The first upper portion is selectively adjustable relative to the first base portion in vertical and lateral directions. The second upper portion is selectively adjustable relative to the second base portion in a vertical direction. In one embodiment, one of the first base portion or the first upper portion includes a vertically extending element movable along an arcuate path within a vertically extending socket defined by the other of the first base portion or the first upper portion. In another embodiment, the first and second mounting members include bearing elements that encircle the first and second scope portions and facilitate angular movement of the firearm scope relative to the upper portions when at least one of the upper portions is moved vertically relative to its respective base portion.

A sighting system for a firearm, configured for securing, about a firearm, the sighting system housed in a housing, with a smart phone or smart device mounting platform rotatably coupled thereon, with an additional rear viewing camera, integral or attachable to an armature. This said armature, additionally passes through an open portion of a clamping device, that is attachable to a threaded base portion, of the back side of said smart device mounting platform, and is both height and angularly adjustable. This said sighting device, provides the target image that is either received from other target viewing devices mounted on the firearm, or provides its own target image, to the smart device, where this said target image is viewable by the user, from any position that the user could position himself in relation to the firearm, by means of the said rotatable smartphone or smart device mounting platform. The image of the area behind the user would also be provided at the same time, by means of the said height and angularly adjustable rear viewing camera, that would either display its image simultaneously in a window of, or on, a split screen on the smart, device's viewing screen, or would provide the image behind the user simultaneously, in its own viewing screen.
