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.

Mounting device for accessories of a firearm, and accessories with such integrated mounting devices, the firearm having guide elements with a recess, where the mounting device has at least one bearing knob and at least one locking spindle configured to cooperate with the bearing knob and the at least one recess. The at least one locking spindle has a selector knob with a resting protrusion, a connection piece and a center part on which at least one locking protrusion is formed. The locking spindle is rotatably and/or longitudinally displaceable in the device housing and is arranged to interact with the bearing knob and the spring.

Systems and apparatuses of a crossbow including a stock defining a front end and a rear end, and a limb including: a fixed end affixed to the stock between the front end and the rear end, and a free end positioned between the front end and the rear end. The limb is configured to flex in a substantially vertical plane.

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 kinematic mount assembly is provided. The kinematic mount assembly includes a fixed mount and a pivot mount. The fixed mount and pivot mount together have a plurality of an protrusions and recesses to guide the mounts into a repeatable position when rotating from an opened to a closed position. The protrusions may be semispherical balls and the recesses may be gothic-arch shaped. The pivot mount and fixed mount may be coupled by a pivot pin and rotate about the pivot pin. The pivot mount may contain holes configured to mount an accessory. A latch assembly may hold the fixed mount and pivot mount closed until the latch is actuated, usually by a switch, to allow the system to open.

A firearm accessory and associated components and methods. The firearm can be a firearm sight, such as a red dot type sight. The firearm accessory includes a base configured to mount to at least first and second different mounting adaptors to permit selective mounting of the firearm accessory to a firearm via the first mounting adaptor or the second mounting adaptor.

Implementations of an adapter plate system for mounting optical sights on a pistol are provided. An example adapter plate system for mounting optical sights on a pistol comprises: a pistol slide, the pistol slide includes an adapter interface, the adapter interface comprising a bottom surface that extends between a first end wall and a second end wall; and an adapter plate, the adapter plate includes a mounting surface on a top side thereof, the mounting surface is configured so that an optical sight can be attached thereto. The adapter plate is configured so that it can be rotated into position between the first end wall and the second end wall of the adapter interface.

A height-adjustable optics mount includes a lower base attachable to the firearm including an angled platform having a plurality of male guiding teeth and located on the lower base; and an upper base which is operable between a slidable position where the upper base is sliding along the plurality of the male guiding teeth and a static position where the upper base is affixed on at least one of the plurality of male guiding teeth.

An electronic weapon accessory system includes an electronic weapon accessory, such as a light, and a detachable mount with an integrated control switch. The electronic weapon accessory includes an electronic component, such as an LED, and a power source disposed within a housing. The electronic component and the battery are electrically connected with a circuit having electrical contacts exposed on an outer surface of the housing. The mount has a body with a clamp structure, a dome switch disposed on an outer surface of the mount body and a circuit having electrical contacts exposed on the outer surface of the mount body. Fasteners removably secure the mount body and accessory housing in assembled relation. When the electronic weapon accessory and mount are assembled, the accessory electrical contacts physically and electrically engaging the mount electrical contacts to complete an electronic control circuit and provide integrated control and operation of the electronic accessory.

A high clarity rifle display beam splitter may include a housing defining a central conduit extending along a length of the housing. The central conduit may include first and second ends. A pellicle frame may be disposed within the central conduit. The pellicle frame may include a surface that is at an angle relative to a longitudinal axis of the pellicle frame. The pellicle frame may be secured to the housing along a central spine of the pellicle frame with a remaining portion of the pellicle frame floating relative to the housing to form an air gap between the pellicle and the housing. A pellicle may be mounted on the surface such that the pellicle is angled relative to the longitudinal axis. The pellicle may have a thickness of less than about 100 microns. Optical window may be coupled with each of the first and second ends.
