  • Patent number: 11441872
    Abstract: A novel and improved rotating stock butt and rotating sight apparatus that applies to a shoulder fired firearm where the firing mechanism and the sight apparatus is elevated above the stock butt when in a horizontal shooting position. This system comprises a cooperation between the rotating stock butt and the rotating sight apparatus that allows the firing mechanism and the barrel of the firearm to be off set to either the right or to the left of the stock butt while the sight of the rotating sight apparatus can be rotated and secured at the top center of the firearm barrel, allowing the shooter minimal head movement in the gun mount.

  • Patent number: 11293721
    Abstract: A scope mount assembly is provided including a scope mount having a reference axis and a level indicator rotatably joined with the scope mount. The level indicator can be rotatable from a stored mode, where a level indicator axis is transverse to the reference axis, to an extended mode, where the level indicator axis is transverse to the reference axis, and the level indicator projects laterally away from the reference axis. The assembly can include a first magnet that magnetically secures the level indicator in the stored mode, and a second magnet that magnetically secures the level indicator in the extended mode. A user rearward of the mount can view the laterally extending level indicator when the level indicator is in the extended mode, and optionally when the level indicator is in the stored mode, to confirm the level of the scope and any weapon to which it is mounted.

  • Patent number: 11268789
    Abstract: New systems, devices and methods for extremely precise aiming and shooting of firearms by relatively unskilled users are provided. In some embodiments, shots may be planned in advance. In some embodiments, a device including specialized computer hardware and software aids a user in planning a shot(s), evaluating the accuracy of the planned shot(s), adjusting the location of the planned shot(s), and executing the planned shots. In some embodiments, the system may prevent shots where motion, acceleration and positioning of the device and/or firearm relative to the planned shot location(s) and/or the surrounding environment may cause an inaccurate shot, but execute shots where those factors facilitate a highly accurate shot. In some embodiments, the control system may similarly account for, counteract and/or otherwise adjust for any other relevant ballistic and other accuracy-impacting factors with a position-actuable firing mechanism to maintain a projected flight path of such a point of impact.

  • Patent number: 9482489
    Abstract: A method for shooting a projectile weapon involves determining the inclination of a line of sight from a vantage point to a target and a line-of-sight range to the target, then predicting a trajectory parameter at the line-of-sight range, for a preselected projectile. Using the trajectory parameter, an equivalent horizontal range may then be determined, wherein the equivalent horizontal range is the range at which the trajectory parameter would be expected to occur if the projectile were shot from the vantage point toward a theoretical target located in a horizontal plane intersecting the vantage point. The equivalent horizontal range may be utilized to compensate for ballistic drop when shooting the projectile weapon. The method may be embodied in a handheld laser rangefinder including a memory for storing ballistic data. Systems for automatic hold over adjustment in a weapon aiming device are also disclosed.

  • Patent number: 9448027
    Abstract: A quick-attach/quick-detach coupler assembly used for mounting a hand guard around a rifle barrel, allowing prompt barrel change. The coupler assembly has a generally cylindrical barrel nut with a plurality of external rail-mounting teeth centrally around its exterior circumference, interior threads for connection to the upper receiver of a rifle, and multiple fastener holes allowing set screws to contact a two-piece separable extension and provide anti-rotational engagement between it and the barrel nut. The barrel nut's interior threads also connect it to the extension. A tool configured as a hand guard fastener and stored/carried on the hand guard is easily accessed to tighten/release the set screws. The tool's handle may also be configured to engage notches on the extension's barrel end and facilitate its release from the barrel nut. The coupler assembly will mount almost every hand guard currently marketed to the upper receiver of the AR family of rifles.

  • Patent number: 9377271
    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.

  • Patent number: 9291424
    Abstract: Systems, apparatuses, and methods for improving situational awareness for a user of a firearm are disclosed. An example camera system for a firearm includes a camera assembly, display panel, a mounting fixture, and switching mechanism. An example camera assembly includes a plurality of cameras fixedly oriented in a plurality of different directions. An example mounting fixture is secured to the camera assembly and configured to be removably attached to a firearm. An example switch is configured to select between the plurality of cameras to cause an image from the selected camera to be displayed on the display panel. An example method includes activating a firearm-mounted camera system, receiving a switch input from a user selecting a camera, generating an image of a portion of an environment with the selected camera, and displaying the image on a display panel to alert the user to conditions in the portion of the environment.

  • Patent number: 9157696
    Abstract: A modular rail assembly for supporting accessories upon a modular weapons platform. The modular rail assembly includes a fore rail preferably positioned above the foretube, and an aft rail preferably positioned above the receiver, which cooperate with one another to enable a modular system whereby one rail may be removed or replaced without affecting the other rail and any accessories mounted thereon. One rail defines a mating member and the other rail defines a mating channel for receipt of the mating member. The rail assembly configuration provides increased flexibility and interchangeability to the modular weapons platform.

  • Patent number: 9033231
    Abstract: Disclosed is an automatic correction apparatus for a trajectory of a projectile from a firearm of which a sight and a gun barrel are installed in parallel, the apparatus including: a distance measurer which is installed in parallel with the sight and measures distance from a target to be hit; a central processing unit which calculates a correction value for parallelization between the gun barrel and the sight so that a trajectory curve and the target can intersect with each other on the basis of the distance measured by the distance measurer; and a parallelization adjuster which connects the sight and the gun barrel and adjusts axial parallelization between a sight line of the sight and the gun barrel on the basis of the parallelization correction value calculated by the central processing unit. With this, the trajectory of the projectile is automatically corrected in accordance with the distance from the target, and thus quick and correct aiming and firing are possible.
