Abstract: In an exemplary embodiment of the present disclosure, a target marker for a firearm may comprise a module having a first portion, and a second portion electrically connected and coupled to the first portion. A light source may be disposed within and electrically connected to the second portion. An optical component may be coupled to the first portion at a first fixed distance from the light source. A circuit board may be electrically connected to the light source via at least one lead, wherein the lead may permit relative movement between the circuit board and the light source and may maintain a second fixed distance between the circuit board and the light source.

Abstract: Devices mountable to a rail having a recoil groove are provided. In one aspect a device mountable to a rail having a recoil groove has a rail positioner having a longitudinal length with a plurality of teeth arranged along an edge of the longitudinal length and a recoil groove insert extending away from the rail positioner and configured to be inserted into the recoil groove, a first body member having a first rail engagement surface and plurality of openings generally sized to receive the plurality of teeth and arranged along a length of the first body a second body member having a second rail engagement surface opposite the first body member, and a clamping structure operable to tighten and maintain a clamping force between the first body member and the second body member when the rail positioner is arranged in therein and that can be released facilitate installation and removal of the mounting to a rail.

Abstract: Laser systems are provided with a semiconductor laser having an emission face, a drive circuit adapted to supply electric energy to the semiconductor laser to cause the semiconductor laser to emit a beam; a user input system adapted to sense a user input action; a controller adapted to control the drive circuit based upon the sensed user input action; a housing within which the laser is positioned and having an opening with a window through which the semiconductor laser can emit the beam. The semiconductor laser is positioned to emit the beam through the window and the emission face of the semiconductor laser is sized to cause a divergence in the beam to create a patterned emission with a predetermined shape without passing the beam through beam shaping optics.

Abstract: The present disclosure relates to a firearm which may include a frame with a first outer wall, and a second outer wall opposite the first outer wall. A laser module may be disposed between the first and second outer walls. An alignment pin may be in communication with the first outer wall and may be configured to move the laser module relative to the frame.

Abstract: Laser systems are provided. In one aspect a laser system has a battery unit and a transistor having a source and a drain in series with the laser and the battery unit with the laser with the transistor having a source, and a gate that allows sufficient current to flow to the laser to allow the laser to emit light when a voltage at the gate is at a higher level and that does not allow sufficient current to flow to allow the laser to emit light when a voltage at the gate is at a lower level. A microcontroller is operable in an active mode and a reduced power mode having an activation input connected to a switch, a reduced power input connected in parallel with the capacitor and an output connected to the gate.

Abstract: A firearm laser sight alignment assembly includes a laser module for emitting a beam along an optical axis, the laser module having an outer seat. The alignment assembly encompasses a resilient grommet mechanically engaging the outer seat in a first adhesive free interference fit. The grommet includes an external seat sized to form adhesive free interferences fits with a laser cover and the housing, as the laser cover engages the housing to retain the grommet with respect to the housing and the laser cover. Upon operable assembly, the interference fits substantially preclude axial and longitudinal movement between the grommet and the laser module as well as the grommet and the laser cover and housing, while allowing angular movement of the laser module to a desired alignment position.
