Firearm associated electronic devices are provided. In one aspect a firearm associated device has a housing having a holding area and an opening through which a removable component may be positioned in the holding area, a door movable relative to the housing and having a door latch that moves along a path as the door moves and a housing latch movable between a first latch position where the housing latch is not in the path to a second latch position where the housing latch blocks movement of the door latch from a first range of positions where the door prevents the removable component from passing through the opening to a second range of positions where the door does not prevent the removable component from passing through the opening. A housing latch biasing member biases the housing latch into the second latch position. When the door latch is in the first range of positions and the housing latch is in the second latch position the door latch is movable along the path but is blocked by the housing latch from passing to the second range of positions.

A portable camera may be activated in response to the activity of a firearm. Furthermore, an individual who discharged a firearm may be identified. Furthermore, information related to the firing of a firearm may be recorded, assessed, identified and transmitted. Furthermore, the status of an implement at a mount may be monitored. Furthermore, a charging device for delivering electrical power to components of a firearm may be used. A communications channel may be established between a firearm telematics sensor and a video camera, optionally by means of intermediary devices. A communications channel may be established between a mount (e.g., holster) telematics device and local and/or remote monitoring service components, optionally by means of intermediary devices. When the telematics sensor detects that its associated firearm has been removed from a holster, is in motion, or is being discharged, the telematics sensor may signal the video camera to initiate recording.

An ammunition monitoring apparatus of the present disclosure includes at least one object-position detection sensor and a controller. The at least one object-position detection sensor is installed near a shell or charge route to face at least one set area and to output position information of each shell or charge in the at least one set area. The controller is configured to determine whether a position range occupied by the shell or the charge in the at least one set area exceeds an allowable position range, based on the position information received from the at least one object-position detection sensor, and to output an alert signal indicating a poor position upon determining that the position range occupied by the shell or the charge in the at least one set area exceeds the allowable position range.

Embodiments of an apparatus configured for attachment to a firearm are described herein. In some embodiments, processing circuitry may be configured to process outputs of one or more accelerometers to identify a firearm discharge event, capture firearm orientation data provided by an attitude sensor and a geolocation of the firearm at a time of the firearm discharge event, and encode a firearm discharge message comprising the firearm orientation data, the geolocation, and the time, for transmission via a communication interface. In some embodiments, the apparatus may be configured for target tagging. Some embodiments are directed to a battlefield information node configured to decode a plurality of firearm discharge messages received, via a communication interface, from one or more other battlefield information nodes. Each firearm discharge message may comprise firearm orientation data, a geolocation, and a time associated with a firearm discharge event. The data from the plurality of firearm discharge messages may be aggregated using a sliding time-window to identify target locations in a hostile zone.

An apparatus converts a pair of poles into a weapon mount by mounting one pole to another pole in order to form an X-shaped configuration with the poles. The X-shaped configuration, formed by the poles, provides a pivot point on which a barrel of a firearm can be supported. The apparatus includes a first brace, a second brace, and a brace-attachment mechanism. The first brace allows the apparatus to attach onto one pole, and the second brace allows the apparatus to attach onto the other pole. The brace-attachment mechanism allows the first brace to be selectively attached to the second brace and, therefore, one pole can be mounted to the other pole in order to form an X-shaped configuration that provides the pivot point on which the barrel of a firearm can be supported.

An interchangeable barrel assembly for a firearm including a novel barrel and tool assembly which are used with a receiver having an open aft end. The tool assembly is configured to be inserted into the receiver open aft end so as to engage the aft end of the barrel. Torque applied to the tool assembly thereby transfers torque to the barrel without transferring forces to the action. This enables the same action to be used with different barrels and the barrel may be removed without removing the receiver or other components of the modular chassis or accessories mounted thereon. Additionally, standard torque may be applied to the barrel for connection to the receiver and firearm precision is maintained.
