A device and method for stabilizing a rifle scope that employs a pocket cut in the bottom of a scope base (picatinny rail) that precisely mates with a key formed on the top of a recoil lug, such that when the scope base is attached to the rifle's action receiver and mated with the lug's key, the lug holds the barrel and the scope base locked in tandem so that they move exactly together during recoil events or any vibrations experienced by the rifle.

An optical sight and system. The optical sight includes a housing including a base. A first support and a and a second support extend from the base. A top support extends between the first support and the second support. The top support extends over an optical element and includes a surface adjacent to the optical element. The top support of the housing defines at least one opening extending above a portion of the optical element. The optical element is supported by the housing between the base, the first support, and the second support.

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.

Devices mountable to a rail having a recoil groove are provided. In one aspect a device mountable to a rail having a recoil groove has a rail positioner having a longitudinal length with a plurality of teeth arranged along an edge of the longitudinal length and a recoil groove insert extending away from the rail positioner and configured to be inserted into the recoil groove, a first body member having a first rail engagement surface and plurality of openings generally sized to receive the plurality of teeth and arranged along a length of the first body a second body member having a second rail engagement surface opposite the first body member, and a clamping structure operable to tighten and maintain a clamping force between the first body member and the second body member when the rail positioner is arranged in therein and that can be released facilitate installation and removal of the mounting to a rail.

Disclosed is a passive shock-absorbing system for a sighting apparatus installed on a device including equipment generating the shocks, the system including two rigid plates substantially parallel to one another, via a first plate secured to the part of the device including the equipment and a second plate secured to the sighting apparatus, the plates being connected to one another by a position return component returning the plates to a determined relative rest position after absorbing a shock. The system is characterized in that the position return component includes a line-point-plane positioning unit with balls between the two plates and a set of elastic return members connecting the two plates to one another. A corresponding device is also disclosed.

A weapon system includes a weapon, a weapon sight configured to sight a target of the weapon, and an electro-mechanical super-elevation (EMSEL) system. The EMSEL system includes a weapon adapter coupled to the weapon, an electronics mount coupled to the weapon sight, a drive assembly coupled to the weapon adapter and the electronics mount, and a controller. The controller is configured to determine that the weapon is changing in angular orientation. The controller is also configured, in response to the determination that the weapon is changing in angular orientation, to control the drive assembly to adjust an angle of the electronics mount relative to the weapon while the weapon is changing in angular orientation such that the electronics mount remains substantially at a predetermined angle relative to the target.

Implementations of an optical sight mounting system are provided. In some implementations, the optical sight mounting system comprises an optical sight having a base configured to be removably secured to an adapter interface of a pistol slide. In this way, the optical sight can be mounted on a pistol and used to aim. The base of the optical sight is configured so that it can be rotated into position within the adapter interface of the pistol slide. As another example, in some implementations, the optical sight mounting system comprises an optical sight having a base configured to be removably secured to an adapter interface of an optical sight mount. In this way, the optical sight can be positioned on a firearm (e.g., a rifle) and used to aim. The base of the optical sight mount is configured to releasably engage a mounting interface of a firearm (e.g., a MIL-STD-1913 rail).

A system and method for a weapon accessory mount is disclosed. The weapon accessory mount is configured to attach a weapon accessory to a rail of a weapon configured to fire a projectile in a projectile path. A flexure is configured to receive the weapon accessory. The flexure includes a first end attached to the rail at a first pivot portion, and a second end opposite the first end attached to the rail at a second portion. The first pivot portion is configured to convert at least a portion of energy of a shock recoil from the weapon from translational energy to rotational energy, the second pivot portion has a similar functionality to the first pivot portion.

Implementations of an adapter plate system for mounting optical sights on a pistol are provided. The adapter plate system may comprise an adapter plate configured so that an optical sight can be mounted thereon, a pistol slide having an adapter interface configured to receive the adapter plate, and, in some implementations, a slide cover plate configured to prevent the adapter plate from rotating while it is positioned within the adapter interface. The adapter plate is configured so that it can be rotated into position between the end walls of the adapter interface. In some implementations, the adapter interface of the pistol slide may comprise a bottom surface having a pivot boss and a rotation stop extending therefrom. The pivot boss and the rotation stop are positioned on the bottom surface of the adapter interface so they are received within a pivot bore and a guide channel, respectively, in the underside of the adapter plate.
