摘要： A breechblock assembly includes a breechblock configured to reciprocate along a top of the firearm receiver between a recoil position and a battery position. An actuator is coupled to the breechblock and is configured to move between first and second positions. A lever on the breechblock in contact with the actuator is movable between a blocking position and a non-blocking position. For example, the lever is generally oriented along the central axis and extends rearward beyond a proximal face of the breechblock. When the actuator is in the first position, the lever is in the blocking position. When the actuator is in the second position the lever is in the non-blocking position. When assembled in a firearm, an end of the lever is positioned to block the hammer from striking the firing pin when the breechblock is out of battery by more than a predefined distance.

摘要： A firearm slide accessory includes a charging handle attachment that includes a base member and a pulling member that extends from the base member. The pulling member includes a pair of side members that extend from the base member and which join to form a cross member parallel to the base member. The side members and the cross member define an opening through which sights of a firearm are viewable.

摘要： A semi-automatic or fully automatic firearm (2) having a barrel (4), the rear end of which is in the form of a cartridge chamber (8), in which each round can be inserted from the rear; a breech body (6) that is movable in a longitudinal direction of the barrel between an open position for releasing the cartridge chamber (8) for reloading a round and a locking position that locks the cartridge chamber (8), wherein in the locking position the breech body (6) closes the cartridge chamber (8) at the rear and the cartridge casing acts as a thrust bearing, wherein the firearm (2) has a breech body locking device (20) that is designed to move a breech body lock from a breech body release position for releasing the breech body (6) to a breech body locking position for locking the breech body (6) and from the breech body locking position to the breech body release position, wherein the breech body locking device (20) has an electromagnet (24) for moving the breech body lock from the breech body release position to the breech body locking position, and/or an electromagnet (24) for moving the breech body lock from the breech body locking position to the breech body release position, as well as a firearm (2) with an electromagnetically driven firing pin (18).

摘要： A sliding breechblock for a cannon includes a translatable, removable insert assembly that contains electrical firing pin and data link modules. The removable insert assembly is translatable in a direction normal to the central longitudinal axis of the barrel thereby enabling removal of the insert assembly without removing the breechblock from the breech ring. Mating portions formed on the breechblock and on the insert assembly prevent displacement of the insert assembly with respect to the breechblock in the direction along the central longitudinal axis of the barrel.

摘要： A spring/rod recoil assembly may be improved with Belleville springs arranged in combinations of nested and inverted stacks that absorb recoil impact energy while providing rebound energy to properly load cartridges from the magazine into the chamber. A firearm assembly may include a cylindrical spring, and guide rod—having stops at both ends—lengthwise situated within the cylindrical spring. The assembly may include a Belleville spring stack captured on the guide rod between a back-end stop and the cylindrical spring, with one or more stacks of nested springs and one or more stacks of inverted springs. The spring stack may be arranged to return some of the recoil energy produced during firing of the firearm, and decelerate slide velocities without damage to the firearm. Each spring has a diameter allowing it to fit within a back chamber where at least the back-end of the guide rod and spring are situated.

摘要： The invention comprises improved designs in a recoil control device comprising a bolt and slider for use in a variety of firearms. In one embodiment, the bolt and slider are articulated so that the displacement of the bolt results in a force component accompanying the slider as it moves along a slider path that traverses a line formed by a linear firing axis of the barrel of the firearm. The slider can have additional structural and functional features, including stabilizing features, vibrational damping elements, elements of the fire control mechanism, and devices to manage the peak impulse of the slider movement as it contacts a base or terminus point.

摘要： Automatic and semi-automatic firearms of remarkably reduced mass yet capable of long-range accuracy because of unique recoil reduction are characterized by (A) a temporary combination of a barrel, an integral breech and a separable chamber that in operation of the firearm is moved by a compressed spring distally before and while a chambered cartridge is fired, (B) run-out of such temporary operative combination diminishes firearm recoil, (C) recoil of the temporary operative combination recompresses the spring and (D) the separable chamber is loaded with a round while spatially separated from the breech and barrel.

摘要： A single shot, falling block rifle is shown having a one-piece stock. The rifle includes a barrel having opposing ends with a receiver mounted on one end of the barrel. The receiver has a rearward face which includes an arch-shaped opening. A breechblock of lesser width than the receiver slides upwardly and downwardly within the arch-shaped opening allowing the size and weight of the action to be reduced. The action also includes a positive sear lock safety and a spring loaded striker which is manually cocked by means of the cooperative action of an operating lever, connecting link and cocking lever.

摘要： Disclosed is a repeating firearm having a vertically slidable block mounted behind the barrel. The upper portion of the block carries a firing pin, and one or more cartridge holding chambers are provided in the lower portion. A cartridge ejector is mounted at the rear of the barrel. The block is slidable between a lower position permitting operation of the ejector, an intermediate position aligning the firing pin with the barrel, and one or more upper positions aligning said cartridge holding chambers with the barrel for transferring cartridges from the chambers to the barrel for firing. In one embodiment a tubular magazine is provided beneath the barrel for holding additional cartridges end-to-end and means are provided for transferring cartridges from the magazine to a cartridge holding chamber in the block, for ultimate transfer therefrom into the barrel.
