  • Patent number: 11614291
    Abstract: An accessory for a firearm includes a deflector structured to alter a path of discharge gasses and/or debris after such gasses and debris pass a Loaded Chamber Indicator (LCI) of the firearm. The LCI indicates a presence of a cartridge within a firing chamber of the firearm, but openings within and around the LCI also provide a path for hot gasses and debris to strike accessories, which causes fouling and other deterioration.

  • Patent number: 11614302
    Abstract: A compressed air gun trigger structure, the air refill lock cooperates with the trigger assembly to facility full auto and semi auto shooting. That is while the pressure of the eject chamber is lower than the set scale, the air refill lock will lock the piston even though the trigger is triggered by user. So the compressed air gun cannot be fired when the pressure is low. When the eject chamber is fully refilled and the pressure will push the air refill lock to releases the trigger and while user triggered the trigger, the compressed air gun is fired. That is the semi-auto mode. If the user keep holding the trigger, air refill lock will automatically trigger the piston for firing when the eject chamber is fully refilled. That is the full-auto mode.

  • Patent number: 11598596
    Abstract: A firearm system is provided. A pump-action firearm, such as a shotgun, includes a buffer attached to a trigger housing. The buffer consists of a resilient or semi-resilient material and is positioned such as to face towards an opening the receiver in which the magazine tube is partially received. The buffer includes a contoured bottom surface and an upper surface, configured in a way which shortens the space available within an opening of a receiver while accommodating the loading of shells into a magazine tube. Upon moving a shell into the opening, such as by pumping the action, the shell impacts the buffer, which stabilizes the shell prior to being lifted by an elevators. For shorter shells, this reduces the risk of a jamming event. For longer shells, the buffer is configured to compress to accommodate the additional length.

  • Patent number: 11592260
    Abstract: An airgun has a high pressure reservoir for providing a pressurized motive gas to a breech to fire a projectile. A regulator is intermediate the high pressure reservoir and a downstream firing pressure reservoir for providing a consistent regulated pressure of the motive gas in the firing pressure reservoir. The airgun includes a bypass line for selectively connecting the high pressure reservoir to the firing pressure reservoir, independently of the regulator. Thus, an operator can select a firing of the airgun with either a regulated gas pressure in the firing reservoir or the pressure of the high pressure reservoir.

  • Patent number: 11592248
    Abstract: An improved gas piston system for the automatic loading of a rifle, especially a rifle of the M-16/AR-15 type. The system employs a barrel nut, or an adaptor to a barrel nut, that has been modified to secure one end of a gas piston system. The other end of the gas piston system, namely the piston rod, engages, either directly or indirectly, the key on a bolt carrier group. This configuration positions the gas piston system at a point starting near the barrel nut and extending to the bolt carrier group of the rifle, while a gas tube extends from the gas block to the gas piston system a point near the barrel nut.

  • Patent number: 11592249
    Abstract: A system includes a movable assembly configured for pushing a piece of ammunition into a breech ring of a firearm and/or closing the breech ring, under control of a motor. A feeding device is configured for feeding the piece of ammunition into a position situated between the movable assembly and the breech ring. A synchronization device co-operates with the motor on one side and with the feeding device on the other side. The synchronization mechanism provides for selective transmission of motion, under control of the movable assembly, from the motor to the feeding mechanism, when the movable assembly is in a position away from the breech ring.

    Abstract: A pellet having a convex shaped front includes a plurality of radially disposed surface slots. The concave shaped rear portion has a matching number of surface ribs that can be frictionally attached to the convex portion's slots. The pellet is constructed of a combination of medical compounds along with appropriate binders and other compounds that are pressed together under high pressure to produce a rigid mass capable of being propelled at high speeds and to pierce the skin of an animal or person where the compounds can be dissolved when contacting the internal liquid portion of the animal or person. The pellet can be loaded and propelled by a standard air rifle, gun, or pistol.

  • Patent number: 11585623
    Abstract: Suppressors and baffles therein provide for sound and/or flash suppression of a firearm. The baffles include a first cone portion, a second cone portion, and a neck connecting the first cone portion and the second cone portion. The first cone portion and second cone portion define a passageway through which hot gases and a bullet may be expelled through and out of the suppressor. The first cone portion directs at least some expelled gases around the outer edge of the first cone portion and to the neck and second cone portion. The second cone portion together with a suppressor body block movement of the expelled gases. A port in the neck allows the expelled gases blocked by the second cone portion to escape toward the passageway to disrupt the flow of the expelled gases and thereby further suppress the sound and/or flash.

  • Patent number: 11585633
    Abstract: Apparatus and associated methods relate to a handgun brace arranged with a rigid structure extending radially away from a handgun trigger guard, and having a forward-facing surface configured to physically engage with at least one finger of a user's non-primary grip hand in a stable position below the handgun's barrel and in front of the handgun's trigger, such that a counter-force applied by the finger(s) at the forward-facing surface tends to prevent the handgun (especially the muzzle), from rising or rotating in response to shooting, such as due to muzzle jump. In an illustrative example, the brace may be releasably fixed to the handgun (e.g., as a modular handgun accessory). A handgun brace that substantially mitigates the unwanted effects of muzzle jump/recoil may advantageously yield higher shooting accuracy and beneficially promote proper handgun grip positioning.
