  • Patent number: 10415912
    Abstract: A gun includes a bolt, a bolt stop member and a shock-absorption device. The bolt is movable forward or backward in a gun body, accumulates a pressure of a buffer spring while moving backward according to manipulation of the gun, and moves forward by releasing the accumulated pressure. The bolt stop member stops the bolt moving forward. The shock-absorption device includes a shock-absorption link which engages with a shock-absorption shaft which acts on the bolt stop member to absorb an impact force applied to the bolt stop member by the engagement of the bolt and the bolt stop portion.

The fixture is made up of several parts that when used in conjunction with one another mitigate the transfer of torque from the barrel nut to the firearms receiver during barrel installation. The fixture affords the user a method and apparatus that holds the barrel in alignment with the firearm receiver and secures the barrel against rotational movement during installation of a barrel nut or similar device. The fixture may be configured to work with the legacy AR15/M16 type barrel nut, as well as other designs as disclosed herein.

  • Patent number: 9476672
    Abstract: Hand guards for firearms and related methods are provided. In one example, a hand guard for a firearm includes an elongated tubular housing having a lumen extending between opposite ends thereof. A hand guard mounting assembly is coupled concentrically to a rear end portion of the housing. The mounting assembly includes a pair of opposing transverse surfaces respectively disposed on opposite sides of a transverse flange located on a front end of a barrel nut extending forwardly from a receiver of the firearm. At least one of the transverse surfaces is longitudinally moveable toward the other transverse surface. A mechanism adjustably urges the at least one transverse surface longitudinally toward the other transverse surface so as to clamp the flange firmly between the two transverse surfaces and such that the barrel of the firearm is disposed concentrically within the lumen of the housing.

  • Patent number: 9410757
    Abstract: A heat dissipating and strength enhancing cover for a firearm gas tube includes a wire helix formed of closely adjacent coils having an inner diameter sized to closely fit over and in contact with an exterior surface of a gas tube. The wire of the gas tube cover may be made of a Beryllium-Copper alloy and have sufficient flexibility to accommodate at least one bend in the gas tube. The ends of the gas tube cover may be formed to a substantially flat surface that is substantially perpendicular to a longitudinal axis of the helix and may include caps covering first and second ends of the gas tube cover. The caps may prevent rotation of the cover when installed. The cover may extend substantially between a gas block and means for mounting a barrel when installed.

  • Patent number: 9395155
    Abstract: An electromechanical system translates an “aiming error” signal from a target tracking system into dynamic “pointing corrections” for handheld devices to drastically reduce pointing errors due to man-machine wobble without specific direction by the user. The active stabilization targeting correction system works by separating the “support” features of the handheld device from the “projectile launching” features, and controlling their respective motion by electromechanical mechanisms. When a target is visually acquired, the angular deflection (both horizontal windage and vertical elevation) and aiming errors due to man-machine wobble (both vertical and horizontal) from the target's location to the current point-of-aim can be quickly measured by the ballistic computer located internal to a target tracking device. These values are transmitted to calibrated encoded electromechanical actuators that position the isolated components to rapidly correct angular deflection to match the previous aiming error.

  • Patent number: 9389033
    Abstract: A strengthened firearm includes at least one metal/composite material formed into at least one firearm component, and a polymer/composite material combined with the at least one firearm component. The metal/composite material replaces the polymer/composite material in a specific area or component of the firearm that may be weak or tend to fail earlier than other areas or components of a polymer/composite firearm. The method of combining the multiple materials allows for additional strength in the firearm.
