  • Patent number: 11371799
    Abstract: An example simulated weapon includes a delayed trigger and a pellet ejector. The delayed trigger includes a chamber and a piston slidable between armed and triggering positions. A spring biases the piston towards the triggering position. A locking member releasably locks the piston in the armed position. Release of the piston by the locking member causes the spring to move the piston from the armed position to the triggering position. The pellet ejector is coupled to the delay trigger to be triggered by the delay trigger in the triggering position. The pellet ejector includes a pressure chamber to receive a pressurized fluid and a pellet chamber to receive pellets. A valve is disposed between the pressure chamber and the pellet chamber communicates pressure from the pressure chamber to the pellet chamber. A barrel that extends through the pressure chamber is connected to the pellet chamber to eject the pellets.

  • Patent number: 11371819
    Abstract: A packaging arrangement for 30 mm×173 mm ammunition rounds. The packaging arrangement has a heavy duty standoff device of defined height, which standoff device mounts a very high strength support plate and a heavy duty restraining plate. The support plate has through holes (of diameter slightly less than the rounds defined maximum diameter) to hold the rounds of in an upside down position and from sliding/moving. The height of the standoff device keeps the rounds from being able to touch the bottom of the metal box. The restraining plate has multiple recessed areas sized to accommodate the back ends of the said rounds. The packaging arrangement is lowered into a metal box with handles for carriage purposes. On top, there are Homosite filler pads, and the box accommodates a top lid.

  • Patent number: 11365946
    Abstract: A system for improving firearm safety is provided comprising a firearm comprising a trigger mechanism for discharging the firearm, a trigger safety member to prevent accidental discharging of the firearm, and an electronic housing contained in a pistol grip of the firearm. The housing receives a message from a mobile device, determines that the message contains an instruction associated with an owner of the firearm, and transmits, based on the instruction, a command regarding the trigger safety member. The electronic housing transmits the command along an internal cable to a motor embedded in the trigger mechanism and receives the message via a transceiver component of the electronic housing. The motor, based on the command, turns an eccentric component to one of block and unblock the trigger safety member. The electronic housing further comprises an externally visible LED indicating one of engaged and disengaged status of the eccentric component.

  • Patent number: 11365945
    Abstract: An assembly for directing propellant gas to an action of a firearm includes a barrel and a gas block. The barrel has a plurality of gas ports that communicate with the bore of the barrel. The barrel and the gas block define a passage that receives pressurized propellant gas from the bore by way of the barrel gas ports, and directs the propellant gas to a gas port of the gas block. The plurality of barrel gas ports and the passage act as a manifold in which the propellant gas is taken from multiple locations within the barrel, combined into a single flow, and directed into the gas block via the gas block gas port. The pressurized gas is then routed to an action of the firearm by way of a gas tube and a gas key.

  • Patent number: 11353288
    Abstract: An illumination device for a firearm may include a housing supporting multiple lamps. A switch actuator of the device is rotationally coupled to a rear end of the housing. A cam is coupled to the switch actuator, such that the cam rotates with the actuator, the cam having a first end including a magnet and a second end having a shaped cam surface configured to interface with a cam follower. The actuator and the cam are biased toward a neutral position. Selective rotation of the cam causes a magnet of the cam to operate one or more magnetic switches. The cam is transitionable between a plurality of discrete positions, e.g., including a pair of toggle positions in the first rotational direction from the neutral position, and a pair of momentary positions disposed on the cam in the second rotational direction from the neutral position.
