A dual clamping device.

A firearm accessory with a primary light oriented in a first direction to assist a user in aiming the firearm and a path light oriented in a second direction to assist the user in seeing a travel path. A motion sensor may actuate the path light. The path light may be positioned below the primary light. The accessory includes a mount for mounting the accessory on a firearm. A housing of the accessory may include lug receivers spaced longitudinally, and a lug received by one of the lug receivers and adapted to engage the groove on a firearm rail for preventing longitudinal movement of the mounted accessory. Actuators for turning the primary light on and off may be positioned adjacent sides of a trigger guard of the firearm when the housing is mounted to the firearm. Mounting features and battery compartment features are also disclosed.

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.

An accessory mount for removably attaching an accessory to a firearm rail includes a base having a mounting rail, a lock block moveable in a recess of the base and a throw lever, which when activated, allows springs to move the lock block in the recess so the lock block disengages the firearm rail in an open mode. The thumb lever also can engage the lock block to a closed mode in which it clamps the mount to the firearm rail in a fixed position relative to the firearm. An accessory thus can be firmly, consistently and securely mounted relative to the firearm with the mount. The thumb lever can be joined with a threaded shaft that engages a threaded element, for example, a keps nut, associated with the lock block. A toggle lock can selectively engage notches in the threaded element to set the overall clamping force of the lock block and mount on the firearm rail.

A crossbow includes a rail and an arrow retention device including a bridge, a supporting element, a rolling unit, and two springs. The bridge includes a first section connected to the rail and a second section extending over the rail. The supporting element is connected to the second section of the bridge. The supporting element includes a pocket intersecting a bore. The rolling unit includes a roller and an axle. The axle includes a middle section for supporting the roller and two lateral sections extending from the roller. The lateral sections of the axle are located in two portions of the bore divided by the pocket. The roller includes a portion located in the pocket and another portion extending from the pocket to contact an arrow. The roller includes a smooth periphery. Each of the springs is compressed between the bridge and one of the lateral sections of the axle.

An accessory rail mountable light includes an accessory rail interface configured to selectively attach to an accessory rail of a firearm, the accessory rail being aligned with the bore of the firearm, at least one light activating button, and at least one light element. The at least one light activating button is reachable by an operator for selectively illuminating the at least one light element and the at least one light element illuminates an area in front and below the firearm when the firearm is pointed forward from an operator.

A scope alignment assembly is provided that can automatically level a scope. The assembly can include a base defining a hole and including a first scope ring, a spring in the hole, and a detent in the hole, the detent urged toward the scope. The scope mount can include a registration element disposed on a lower portion of the scope, distal from a turret assembly. The detent and/or registration element can be operable in a transition mode in which the detent moves along a scope surface while the scope is rotated about an axis of rotation, and a levelling mode in which the detent is configured to register with the registration element to provide at least one of a visual feedback, an audible feedback and a tactile feedback to indicate the scope is level relative to the base. A related method of use also is provided.

A quick detach mounting system includes a base, an adapter, and a lock. The base includes a frame, a guide atop the frame, and a clamp configured to secure the base with a rail. The adapter includes a central beam, a platform atop the central beam configured to provide a securing point for accessories with the adapter, and an interface extending below the central beam engageable with the guide in order to couple the adapter with the base. The lock integrates with the base and is moveable between a lock position that secures the adapter with the base and an unlock position that releases the adapter from the base.

An adapter assembly for mounting an optic on a firearm using nuts mountable on bolts, threaded studs, or threaded posts is provided. The adapter assembly may include a bracket having a bottom section to mount to a firearm assembly, and a top side to receive the optic; wherein the threaded posts are integrally formed on the top side of the bracket, or wherein the bracket includes: pockets arranged to mate with at least part of heads of the bolts or studs, the pockets on a bottom side of the bracket; and through openings to receive shanks of the bolts or a different part of the heads of the bolts, or shanks of the studs. Other embodiments may be disclosed and/or claimed.

A system, method, and device for configuring an optical aiming device for ballistic drop compensation (BDC). The optical aiming device can include a housing with a reticle pane defining a reticle display field viewable by a user and indicating a zero point, the housing further including a plurality of axially spaced lenses and defining an optical path therethrough. In various embodiments the system includes a display device configured to project an image generated from a display, a processor, and a non-transitory computer readable storage medium. The computer readable data storage medium can include instructions executable by the processor to receive a first set of ballistics input data indicating a first type of ammunition, determine a BDC pattern including at least two holdover marks corresponding to at least two ranges for the first type of ammunition, and project the BDC pattern onto the reticle display field.
