Systems, methods, and computer program products for detecting, locating, and identifying gunshots. In response to detecting a discharge of a firearm, a discharge alert indicating one or more characteristics of the discharge is transmitted to a gunshot location system. The one or more characteristics of the discharge are compared to one or more characteristics of one or more gunshots detected by the gunshot location system based on acoustic signals received at one or more listening stations. In response to finding a match between the one or more characteristics of the discharge and the one or more characteristics of acoustically detected gunshot, the gunshot is associated with the firearm.

An optical apparatus flexible stop has a flexible surface element, which is flat/planar in a first state and rolled or wound into a hollow roll in a second state. Two tensioning cords guide around the hollow roll to hold the hollow roll shape. An optical apparatus is provided with a tubular body containing an optical unit and having a first open tube end, an attachment device having a device housing, wherein an optical through passage of the device housing is arranged in front of the open tube end, and the flexible stop. The flexible stop is rolled or wound around the open tube end of the tubular body and the optical through passage of the device housing, held in the shape of a tube with the tensioning cords, thus forming an optical tunnel between the open tube end and the optical through passage.

A cover kit for a firearm handguard having a plurality of slots, the cover kit includes a bottom side detachably mounted on the slot of the firearm handguard; fastening means for securing the cover body to cover the slot on the firearm handguard; a cable secured between the bottom side of the cover body and the firearm handguard; wherein the bottom side comprises a plurality of horizontal tunnels and a plurality of transversal tunnels intersected with the transversal tunnels; wherein the cable is embedded in at least one of transversal tunnel and/or the horizontal tunnels.

A magazine baseplate configured to receive a tool and the corresponding tool are described herein. The tool is configured to fit into a tool indention on the bottom side of the magazine baseplate and be secured therein. The tool has a front end and a rear end, each of which has various tools or heads, such as a flathead screwdriver or T10 torx head.

Systems and methods are provided for weapon monitoring, including a weapon measurement system with one or more sensors that record longitudinal operational information of a plurality of weapons and are used to produce a plurality of signals, a connection point that receives the plurality of signals within a deployment location, a server device running application software that uses the plurality of signals received from the plurality of weapons to detect and store longitudinal situational state data of each weapon of the plurality of weapons, and a machine learning system that uses the longitudinal situational state data to calculate a weapon system failure state.

An electrical power source for a firearm includes a housing, one or more rechargeable power cells stored inside the housing, and a microcontroller unit that receives data on a condition of the one or more rechargeable power cells. A network interface controller embeds the data onto an electrical circuit that is configured to be received by a firearm accessory mounted to the firearm. The data embedded on the electrical circuit is usable by the firearm accessory to provide a status of the electrical power source.
