An embodiment firearm accessory mount includes: a main base including: a firearm groove at a bottom of the main base; and a mating groove at a top of the main base, the mating groove extending from a front of the main base to a rear of the main base, a first width of the mating groove decreasing continually in a first direction extending from the front of the main base to the rear of the main base; and an accessory mount including: an accessory groove at a top of the accessory mount; and a mating slide at a bottom of the accessory mount, the mating slide extending from a front of the accessory mount to a rear of the accessory mount, a second width of the mating slide decreasing continually in a second direction extending from the front of the accessory mount to the rear of the accessory mount.

A firearm optic assembly has a body, the body having a first mounting facility configured to removably connect the body to the firearm, the body having a first receptacle configured to receive a first accessory, the body having a second mounting facility configured to removably receive a second mount portion associated with a second accessory offset from the medial plane, the second mounting facility including a pocket defined by one of the body and the second mount portion, the second mounting facility including a protrusion on the other of the body and the second mount portion, the protrusion being configured to be slidably or loosely received in the pocket, the protrusion having a free end and an opposed base end, the second mounting facility having an alignment facility including flared surfaces at the base end, and the flared surfaces being on opposing sides of the protrusion.

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 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.

Certain aspects of a novel weapon sight system combine a direct view, a visible light video view, and an infrared (IR) video view mode. Each of the view modes may be viewed individually or simultaneously with one or more of the other view modes through a single viewing aperture. Further, the one or more view-modes may be provided while providing a bore-sighted reticle superimposed on the selected view. Further, the reticle may be powered separately from the video view electronics enabling use of the reticle regardless of the power status video view electronics.
