  • Patent number: 10234245
    Abstract: A ballistic shield may include multiple ballistic plates. The first plate may be smaller contain a handle and viewport and be able to connect to a second plate. The second plate shall be able to connect to the first plate and when combined, can create a larger shield using only the handle and viewport of the first plate. Other plates may be connected to the second plate to increase the ballistic coverage required. A rotating plate can be connected with a hinge and spacer. When dropped the rotating plate would enable extended coverage. When the rotating plate is rotated upward, an additional layer of ballistic coverage is provided.

  • Patent number: 10048028
    Abstract: Because of a clearance between a barrel supporting member and a barrel, a rotational movement of the barrel is not always constant. Thus, trajectory of a bullet is misaligned. A counterweight 40 is located upper than a barrel 10, and rings 61, 62, which are support portions, are located nearer to the counterweight 40 than a gravity center of the barrel 10. Since the barrel 10 is located lower than the counterweight 40 and engaged with a lower surface side of a gear 30, when a bullet is shot and the barrel 10 is moved backward, a force to rotate the barrel 10 itself clockwise is imparted by a circular surface shape of the gear 30. The barrel 10 receives a force to be rotated clockwise from the gravity center position, the ring 61 and the ring 62, and the barrel 10 is in contact with the inner surface of the barrel supporting member 50. Thus, in spite of the existence of the clearance, the barrel 10 is not displaced in the barrel supporting member 50.

  • Patent number: 9995551
    Abstract: A universal custom recoil solution will comprise of, a provided firearm or barrel, prismatic shaped shell housing mounted or connected to the gas block, a gas block with pathways to direct firearms gas pressure from firing bullet into device interior pushing a counter weight, and spring to counter act the firearms recoil when fired. This device is fitted to or around a provided barrel where the counter weight and spring are mounted on and reciprocate from front to back of the systems interior volume. The systems main function is to create a counter balance to the firearms kinetic energy by providing a moving mass, to counter the recoil from the firearms action movement when firing. The gas pressure is also expelled and redirected allowing the device to cycle synergistically with the firearm actions.

    Abstract: A machine gun and associated armament apparatus, including an ammunition box for supplying belted ammunition to the gun, are exteriorly supported on a landing gear sponsor tow plate of a helicopter, adjacent a cabin area gunner's window, using a specially designed pintle support structure. The machine gun is horizontally rotatable about a vertical azimuth rotation axis which is forwardly tilted and substantially parallel to the similarly tilted rotor mast axis. The gun's upward firing elevation angle is limited to 1.5 degrees when the gun is pointed forwardly. However, due to the forward tilting of the gun's azimuth rotation axis, its maximum upward firing elevation angle automatically increases as the gun is swung rearwardly, thereby desirably increasing the gun's firing range to the side and rear of the helicopter while at the same time automatically maintaining the bullet path of the forwardly pointed gun safely below the forwardly drooped operational rotor tip path.
