Systems, devices, and methods are provided, wherein a device is attachable to or integrated in a firearm and includes a plurality of sensors that are each configured to sense a respective attribute of the firearm or of an environment surrounding the firearm, and are further configured to provide corresponding signals based on sensing the respective attribute. The systems, devices, and methods may be configured to determine an event from among a plurality of events based on the corresponding signals provided by the plurality of sensors. Systems that include the device may record event data and transmit the event data to various user systems for situational awareness, record keeping, training, and other organizational or legal-process purposes.

A movable position-limiting quick-release gun light, comprising a light main body, a bottom end of the light main body is fixedly connected with a support plate, and the left and right sides of which are slidable connected to the top of a base, the middle part of the fixing plate is fixedly connected with a tightening seat, the middle part of the right end of which is fixedly connected to the left end of the tightening rod, and the right end of which is rotatably connected with an tightening handle through a rotating shaft, the front and rear parts of the right end of the tightening seat are fixedly connected to the left end of the ejector rod. The structure of the gun light is simple, the maintenance and disassembly are easy, and the use is very convenient.

A sight magnifier assembly is configured to be releasably secured to a rail feature of a firearm to be used with a sight assembly to enhance a downrange image. The sight magnifier assembly includes a base configured to be releasably secured to the rail feature of the firearm and a housing rotatably coupled to the base. The housing is configured to support sight optics used to enhance or improve the downrange image. The assembly further includes a mechanism configured to enable the rotation the housing with respect to the base between a use position in which the sight optics is configured to be used with the sight assembly and a stored position in which the sight optics is moved so that the housing and the sight magnifier assembly is nearly completely obscured from the operator by the sight assembly as viewed along a longitudinal axis.

A linear crossbow operates in a linear manner parallel to an arrow flight path. The linear crossbow includes a plurality of limbs and a rotatable string let out assembly. The limbs include free ends that are drawn towards the rotatable string let out assembly as a drawstring is pulled rearward. The limbs power the drawstring to propel an arrow along the arrow flight path from a front end of the crossbow.

An integrated grip and rail adapter for a handgun includes two side panels having both grip sections that are adapted to form at least portions of the handgun grip and receiver sections that are adapted to extend from the grip sections along the receiver frame of the handgun beyond a trigger guard and beneath a barrel of the handgun. A mounting rail for mounting accessories beneath the barrel of the handgun is formed in the two receiver sections.

A modular handguard device configured to be slidably mated to an outer surface of an existing or affixed handguard. The handguard of the present invention may be configured to mate with any handguard to provide an extension of the handguard for purposes including mitigation of detectable heat signature, operator safety and increased reconfigurability of firearms for mission specific needs.

A lever-based clamping device.

The devices and methods described below provide for a forearm handguard for a rifle with multiple integrated power and communication channels that are accessible to any accessory through the different rail interface systems of the handguard. Any suitable rail interface systems may be used.

A mounting rail for a firearm is described, wherein the rail includes at least one catch arranged on a flat upper surface of the rail. The at least one catch serves as a means of fixation for at least one accessory. The rail also includes a housing that extends longitudinally, and the housing is suited to receive a printed circuit board allowing for an electrical connection with the accessory. The housing is partially defined by at least one recess, each recess being arranged between two opposite flanks of the corresponding catch. A top of the corresponding catch extends transversely on either side of a median plane of the rail above the housing.

A coupling mechanism comprises a first engaging portion constructed and arranged for direct coupling to a handguard of a firearm; a second engaging portion constructed and arranged for direct coupling to a body of the firearm; and at least one reinforcement element extending between the first engaging portion and the second engaging portion for applying a force that maintains an interface formed between the handguard and the body of the firearm.
