In one embodiment, the receiver and magazine may be formed as a unitary integral structure formed as either a single piece or in half sections coupled together.

Abstract: Embodiments of the invention relate to a dynamic suppression mechanism for a semi-automatic firearm. An axial mass is positioned adjacent to multiple dynamic volume chambers, which are aligned within a housing. An aperture is provided within the mass and aligned chambers to accommodate the projectile. As the projectile travels through the aperture across the length of the housing, each of the chambers is subject to a dynamic expansion and contraction, with the dynamic volume change absorbing byproduct of the traveling projectile.

Abstract: A tactics support apparatus includes an operation unit configured to calculate a friendly military power necessary for each of defense areas which are set between an enemy and a target of the enemy based on a total quantified military power of deployed movable weapons of the enemy and a friend, and determine friendly movable weapons to be deployed in each of the defense areas.

Abstract: A magnetically actuated sear for simulated firearm training is disclosed. The magnetically actuated sear includes a magnet and a magnet catch. The magnetically actuated sear facilitates a crisp trigger break thereby replicating the actual sear release of a firearm. The application of a suitable external trigger force causes the magnet catch to travel along the fulcrum away from the magnet. The greater the difference between the holding force when the magnet is in direct contact with the magnet catch and the attraction force between the magnet and the magnet catch, the crisper the magnetically actuated sear will feel. The magnetically actuated sear can be designed so that slack or trigger creep of the magnetically actuated sear can be matched to the actual firearm's slack or trigger creep.

Abstract: A retrofit apparatus is disclosed for a gas-operated reloading firearm having a pressure control unit to operate the firearm in either manual or semi-automatic operation. The pressure control unit is coupled to the reloading unit to reduce a gas flow to the reloading unit in a first configuration and allow the gas flow to the reloading unit in a second configuration. A controller is coupled to the pressure control unit to operate the firearm in the first or second configuration. The firearm operates in a first configuration requiring manual operation until it receives continuous manual actuation to enable the reloading unit in a second configuration.

Abstract: Provided is a charge feeding apparatus including: a plurality of containers storing a plurality of charges; a chain link configured to connect the containers extending in a first direction and arranged in parallel to one another and configured to rotatably change positions of the containers; a chain driver configured to transmit a rotational force to the chain link to transfer a container of the containers to a discharge position; a rod configured to transfer at least one charge of the charges in the first direction of the container to discharge the at least one charge from the container located at the discharge position; a loading container configured to store the at least one charge discharged from the container located at the discharge position and comprising an opening which exposes the charge; and an extractor configured to extract the charge from the loading container via the opening.

Abstract: A striker-fired firearm in one embodiment includes a trigger assembly including a trigger and trigger bar supported by a frame, a rotatable sear operable to hold a spring-biased striker in a cocked ready-to-fire position, and a rotatable sear blocker operable to prevent rotation of the sear. The trigger bar is operably linked to the sear and blocker such that pulling the trigger rotates the sear and blocker. When the blocker is in a blocking position, the blocker engages and prevents movement of the sear and release of the striker in the absence of a trigger pull. When the blocker is in a non-blocking position effectuated by pulling the trigger, the blocker disengages the sear which rotates and releases the striker to fire the firearm.
