    Abstract: A muzzle brake has body having a muzzle end and an exit end with at least one side connecting the ends. A muzzle aperture in the muzzle end is sized and configured to fit a firearm muzzle. A projectile aperture in the exit end extends to the muzzle aperture. A line segment within the space of the muzzle aperture aligns with the centerline of the firearm and defines a projectile line through the body. Apertures pass through the body with their generating lines being perpendicular to the projectile line. The apertures are shaped to allow more gases to escape in one direction and to contain gases in the opposing direction. This causes the gases to exert forces on the muzzle brake which compensates for the tendency of the muzzle to rise when the firearm is fired.

  • Patent number: 11067354
    Abstract: A breech for noise reduction in a recoil-less weapon is described. The breech is adapted to be arranged in fluid communication with a launcher of the weapon to release exhaust gas. The breech comprises a venturi tube. The venturi tube has an inlet at a first end adapted to be connected to the launcher, and an outlet for releasing the exhaust gas at a second end, wherein the area of the outlet is larger than the area of the inlet. The venturi tube further comprises an exhaust gas controlling element formed at the venturi tube structure. The exhaust gas controlling element is arranged to control the release of exhaust gas so as to decrease a sound pressure peak at the weapon. The inner envelope surface of the venturi tube is configured, such that the inner envelope surface does not alter or at least has a very small influence on recoil characteristics of the weapon.

  • Patent number: 11015895
    Abstract: An apparatus implementable on a pistol includes a compensator and a guide rod. The guide rod has a front distal end and a rear distal end opposite the front distal end. The compensator includes a muzzle brake having a recoil-reduction device, a first through hole and a second through hole. When the compensator is implemented on the pistol: (a) the recoil-reduction device redirects propellant gases to counter a recoil force upon firing of a round of ammunition by the pistol; (b) the first through hole is aligned with a barrel of the pistol to allow firing of the round of ammunition, and (c) the second through hole receives the front distal end of the guide rod therein such that an interface between the guide rod, the muzzle brake and a slide of the pistol is keyed to prevent rotation of the guide rod.

  • Patent number: 10969188
    Abstract: A firearm suppressor configured for coupling to a firearm with its stock barrel bushing removed. The firearm suppressor includes a barrel bushing feature, a recess, and a release. The barrel bushing feature duplicates the barrel bushing of the firearm, which constrains the movement of the barrel of the firearm. The recess is positioned below the barrel bushing and is configured to receive and retain a cap of a recoil spring plug of the firearm. The firearm suppressor is coupled to the firearm when the cap of the recoil plug of the firearm is retained in the recess. The release is configured to press against the recoil spring plug of the firearm. Actuating the release pushes the recoil spring plug of the firearm away from the firearm suppressor, such that the firearm suppressor is removable from the firearm in the same manner as the original barrel bushing.

  • Patent number: 10941998
    Abstract: A Glock compensator integral with a barrel, and a slide assembly allow escaping gases to dampen recoil associated with firing a Glock firearm. The Glock barrel is removed from the front of the firearm allowing for the integrated compensator at the front of the firearm. Various features, including a lock design, debris port, swept back side ports, height offset, nose ring design and mass-reducing rear cutout, result in an efficient and effective integrated compensator suitable for 4th and 5th generation Glock firearms. The compensator and barrel may be fabricated from the same piece of billet. A pair of side rails may be positioned and configured to slidably receive a slide assembly.

  • Patent number: 10935338
    Abstract: The suppression device and system attaches to the muzzle end of the barrel. A vent in the suppression device releases the gases from the barrel in a direction to compensate for drift and recoil. The suppression device adjusts to change the direction and distance from the user at which the device vents the gas. The user adjusts the positioning of the vent on the barrel to control the distances from which the vent is located from the user. The user also adjusts the direction of the vent. The vent directs the gases in a direction chosen by the user from a location designated by the user. Such adjustability enables the user to adapt the suppressor device to the user's specific needs.

  • Patent number: 10890403
    Abstract: Methods and systems are provided for a firearms suppressor adapted with blowout panels. In one example, the blowout panels may be configured to have a lower tolerance for pressure than the materials from which outer components of the suppressor are formed. During over pressure events of the suppressor, the blowout panels may rupture, thereby dissipating pressure in the suppressor.
