A laser accessory device comprises a housing having a front side having a port, a rear side opposite the front side, a left side, a right side opposite the left side, a top side, and a bottom side opposite the top side. One or more laser emitters within the housing are configured to emit a beam through the port. A first cover assembly is positioned on the front side, the first cover assembly including a first safety cover and a first frame securing the first safety cover to the housing. The first safety cover is movable between a closed position covering the port and an open position not covering the port.

The present disclosure provides systems and techniques for an attachment that can be fastened to a gun. The attachment may include a top surface having a longitudinal axis and an aiming sight that is parallel with the longitudinal axis, a front surface having a latitudinal axis that is perpendicular to the longitudinal axis, the front surface including a muzzle aperture, a left surface, a right surface, and a fastening system. The fastening system may include a first mounting aperture of the left surface, a second mounting aperture of the right surface, and a locking pin capable of being positioned in the first mounting aperture and in the second mounting aperture such that the locking pin fastens the attachment to the gun. The attachment may be fastened to the gun such that the longitudinal axis is parallel with a longitudinal bore axis of the gun.

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.

A clamping structure and a tactical light, wherein a sliding groove is provided on a bottom part of a clamping space; a plurality of first positioning areas are provided inside the sliding groove along its length direction; a sliding block is slidably provided inside the sliding groove; a plurality of first positioning portions are provided on a side of the sliding block facing the first positioning areas; an abutting component is fixed on the sliding block; when the sliding block slides inside the sliding groove, the abutting component slides along with the sliding block inside the clamping space to adjust the position of the sliding block relative to the clamping device, also, each first positioning portion moves from one first positioning area to another one, thereby fixing the sidling block inside the sliding groove, and realizing adjustment of the position of the clamping device relative to the sliding block.

A direct enhanced view optic (DEVO) provides a user with enhanced target acquisition information, such as real time ballistic solutions, fused thermal imaging, extended zoom, and automatic target recognition. The direct view optic may include an optical device having a front objective, a rear ocular exit, and a waveguide. The front objective and the rear ocular exit may be separated by the waveguide, and the optical device provides a distant image onto a display. A diffractive based holographic display system is coupled to the optical device, and the holographic display system provides a see-through information overlay on the display.

A handgun may include a slider-integrated active illumination sight. By integration of electrical connectors into the slider that conduct power from a rear powered sight to a front sight mounting area, a light source inside the front sight can emit light to the shooter's eye and make the front sight visible in any light condition. In combination with actively illuminated rear sight marks, the user now sees three evenly illuminated aiming marks. Alternatively, light can be conveyed from the rear unit to the front aiming marks by means of fiber optics.

A barrel-mountable accessory to couple to a muzzle end of a firearm barrel, including: a first side having an opening arranged to fit around the muzzle end of the barrel; and a second different side having a taper pin opening; and a taper pin insertable into the taper pin opening of the barrel-mountable accessory, wherein the taper pin includes: a length including a first region arranged to mate with a taper interface provided on the muzzle end of the barrel; the length further including a second region to contact a sidewall that defines the taper pin opening of the second side; and means for driving the taper pin into the taper pin opening, wherein the driving means is located on an end of the taper pin.
