  • Patent number: 11585636
    Abstract: A laser bore sight with arbor system is disclosed which includes a bore sight with a housing, a laser and an activation switch. The system also includes a plurality of arbors, each arbor having a sleeve with an interior channel configured to be received the bore sight. Each arbor is configured to fit within the bore and/or breach of a firearm. The exterior configuration of each arbor is different and specifically configured to fit a specific caliber of firearm. The sleeve has a rear end to which is coupled an end cap having and opening through which the bore sight activation switch extends.

  • Patent number: 11162761
    Abstract: An adjustable laser sight is described to be utilized with a firearm and a select ammunition having a known trajectory. The sight has an outer housing and a movable laser diode. The sight also includes a vertical adjuster for varying the vertical angle of the diode. The vertical adjuster has a turret with a series of detent holes therein which mesh with a spring biased detent. The turret detent holes are unevenly spaced from each other, with the spacing increasing between each successive pair of turret detent holes. Each turret detent hole is associated with a progressively increasing incremental target distance mark on the turret. A first bushing is rotatably coupled to the turret and is rotatably coupled to a second bushing with camming members. The second bushing also has an internally threaded adjustment screw therein for even adjustment of the laser diode.

  • Patent number: 6900730
    Abstract: A heat source locator (10) is disclosed having an elongated housing (11) in which is mounted a thermal detector (21), an infrared laser (22), a visible laser (23), and a light bar (25) all coupled directly or indirectly to the outputs of a semi-conductor (27). The thermal detector (21) is mounted within the housing (11) to sense a thermal input within a field of view FV along a central longitudinal axis LA. The infrared laser (22) is mounted within the housing (11) to transmit an infrared laser beam IRB generally parallel to and closely adjacent the longitudinal axis LA. The visible light (23) is mounted within the housing (11) to transmit a visible light laser beam VB generally parallel to and closely adjacent the longitudinal axis LA. With this construction, a target may be generally located by the thermal detector and the location pinpointed through an illumination of the target by one of the lasers.

  • Patent number: 6622414
    Abstract: A laser bore sight (10) is disclosed hollow, outer housing (11) having an internally threaded, rear portion (14), and a threaded end cap (17) is sized and shaped to be threaded to the housing rear portion (14). The end cap (17) includes a threaded, tubular stem (18) having an annular rim (18′), an electrically insulative spacer (20) and a spring (21). The bore sight (10) also includes a laser diode (24), lens (25), a series of three batteries (26), an electrically conductive spring (27), and an electrical conductor. The end cap (17) is movable between an extended position with the spacer protruding from the end of the stem (18) and a retracted position with the spacer recessed within the stem so as to allow the battery to electrically contact the end cap.
