The structure of the gun light is simple, the maintenance and disassembly are easy, and the use is very convenient.

A firearm barrel tray having a barrel channel and a firearm accessory mounting interface, wherein the firearm barrel tray is configured to be attached to a firearm stock such that the barrel channel sits on a first side of the firearm stock and the firearm accessory mounting interface is configured to align with a recess on a second side of the firearm stock.

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.

An automatic zoom-sensing riflescope display adapter (RDA) system can illuminate an iris of a user with a beam from a light emitter. The RDA system can activate a display which includes at least one graphical element visible by the user through an eyepiece. Additionally, the RDA system can focus an image of the iris on a sensor. The RDA system can determine a diameter of the iris from the image of the iris using an iris analyzer. The RDA system can develop a calibration table that correlates the diameter of the iris to a zoom level of an optical scope. The RDA system can estimate the zoom level of the optical scope from the diameter of the iris via the calibration table. Additionally, the RDA system can adjust, to match the zoom level, a font size of the at least one graphical element of the display.

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.

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.

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.

Implementations of an integrated optical sight mount are provided. In some implementations, the optical sight mount may be integrated into the frame of a handgun via a locking block and used to position an optical sight over the slide thereof. In some implementations, the integrated optical sight mount may comprise a mounting platform that is supported by a first side wall and a second side wall, each of which extend from a locking block seated in the frame of the handgun. In some implementations, the mounting platform is configured for an optical gun sight to be secured thereon. In some implementations, the mounting platform and the side walls define an opening therebetween configured (e.g., dimensioned) so that the slide assembly of the handgun is able to pass therethrough without interference.

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.
