摘要： A modular two-piece bolt system for firearms with blowback actions provides a rear bolt piece which detachably couples to plural different front bolt pieces each of different mass. The front bolt pieces have a similar configuration and common coupling interface which forms an interlocked relationship with a complementary configured coupling interface on the rear bolt piece to prevent axial separation of the pieces when the action of the firearm is cycled. The system allows various front bolt pieces to be selected and used interchangeably with the rear bolt piece so that a front bolt piece of proper mass can be matched to the energy of ammunition to be fired. The front and rear bolt pieces when coupled define a continuous extended longitudinal passage which receives the rear breech end portion of the firearm barrel therethrough to reduce the projected length of the barrel.

摘要： An electromagnetic actuator includes characteristics of very fast actuation, shock invariant design, and compact size. The actuator may be controlled via a small low voltage power source such as a battery and simple switching logic. Such characteristics are ideally suited for incorporating the actuator into the firing mechanism of a firearm, which are subjected to drop tests to confirm the firearm will not discharge in the absence of trigger pull. Very fast snap-like action is attained by balancing the magnetic forces of two opposing permanent magnets around a stationary yoke and rotating member to create three circulating magnetic flux circuits. A central electromagnet coil amplifies the magnetic flux of one side of the rotating member or the other depending on the power source actuation polarity, thereby creating two possible snap-like actuation positions. The actuator is usable in firing mechanism release or enabling/disabling applications, and interfacing with other type mechanical linkages.

摘要： forward closed breech position in battery with the barrel and rearward open breech position, a cockable hammer controlled by a trigger, and a bolt release mechanism operably interacting with the bolt. The mechanism may comprise a user-actuated release button and spring-biased disconnect lever coupled thereto and selectively engageable with the hammer. Upon firing, the bolt travels rearward under recoil contacting and partially rotating the disconnect lever to engage the hammer, while simultaneously engaging the hammer which holds the bolt rearward. Actuating the release button fully rotates the disconnect lever to disengage the hammer from the bolt which returns to its forward position via a recoil spring to reclose the breech. A dual interlock safety in one position provided by the release mechanism prevents pulling the trigger and in another position prevents actuating the release button.

摘要： A magnetically variable firing system for a firearm includes a trigger mechanism allowing a user to selectively adjust the trigger pull force-displacement profile by changing the static magnetic field in the mechanism. In a closed magnetic loop configuration, the trigger mechanism includes a stationary yoke and pivotably movable trigger member. The trigger member includes a trigger portion and working portion operably interfaced with the firing mechanism of the firearm for discharging the firearm. An openable first air gap formed between the trigger member and yoke is maintained in a closed position via magnetic attraction therebetween absent a trigger pull. A control insert movable relative to a second control air gap in the yoke allows adjustment of the static magnetic field to alter the trigger pull force required to actuate the trigger mechanism. Other embodiments provide open magnetic loop trigger mechanism designs adjustable to magnetically vary the trigger pull force.

摘要： A magazine for a firearm such as long guns comprises a housing defining a cavity for holding a double staggered stack of cartridges and spring-biased tiltable follower for dispensing the cartridges into the action of the firearm. Features include an accordion type flat spring specially configured to fold into a flat condition in which adjacent bends of the spring are arranged side-by-side to reduce the folded height of the spring. The follower includes bosses slideable in mating vertical housing slots to guide the follower upward/downward motion and allow front to rear tilting action. A coupling mechanism includes a plurality of interlocking mounting teeth forming a selectively interlocked arrangement for detachably assembling the floor plate to magazine housing. A resilient snap fit tab on the floor plate secures the coupling. The magazine is longitudinally elongated and configured to fit flushly with the underside of the firearm when mounted.

摘要： An integrally suppressed firearm in one embodiment includes a rear firing portion defining an axial projectile bore and front suppressor portion. The suppressor portion includes a longitudinal stack of sound suppression baffles each defining a gas expansion chamber in fluid communication with the projectile bore. A mounting rod extends rearward from a front end cap of the suppressor portion and threadably engages a mounting adapter that removably couples the suppressor portion to the firing portion. A muzzle cap disposed inside a rearmost baffle removably couples the mounting adapter to the firing portion. When tightened, the rod axially compresses the baffle stack and forms a combustion gas tight enclosure without need for an additional external pressure retention tube or sleeve. The baffles are configured to form a press-fit frictional interlock with each other such that the baffle stack is self-supporting. An optional accessory rail may be coupled to the adapter.

摘要： An electromagnetically variable firing system for a firearm is disclosed which may include a trigger assembly or mechanism comprising an electromagnetically-operated control device which allows the user to select and adjust the trigger pull force-displacement profile electronically. In one embodiment, the control device may be an electromagnetic trigger mechanism comprising an electromagnetic snap actuator operated via a microcontroller. The microcontroller is configurable by a user to adjust the trigger force-displacement profile according to preset user preferences. The microcontroller energizes the actuator during a trigger pull according to a preprogrammed trigger force and/or displacement setpoint aided by a trigger sensor(s). The energized actuator creates a magnetic field which dynamically increases or decrease the trigger force required to fully actuate the trigger to discharge the firearm. In other embodiments, the control device may be an electromagnetic magnetorheological fluid actuator.

摘要： A shell loading system for a firearm in one embodiment includes a barrel, receiver, reciprocating slide and bolt assembly, tubular magazine, tilting carrier operable to receive and feed shells from the magazine into the action, a spring-biased carrier latch laterally moveable to engage the carrier, and a pawl pivotably mounted on the carrier. A carrier latch disconnect is movable between an unblocking and blocking position that prevents engagement of the carrier latch with carrier. To prevent bouncing of the carrier after firing a shot, a first detent feature on carrier assembly automatically engages a second detent feature in the receiver as the carrier returns downward from an upward position when the action is cycled by discharging the firearm. The detent features automatically disengage when the slide moves rearward to permit normal operation of the carrier when cycling the action.

摘要： A light-weight firearm and related fabrication method are described for a wear resistant feed ramp for chambering cartridges from an ammunition magazine. In one embodiment, the firearm includes a barrel and a frame defining a magazine well and cartridge feed ramp. A wear insert formed of a different material than the frame is implanted in the feed ramp adjacent to the barrel chamber. The wear insert is then machined in situ to shape forming an obliquely angled wear surface. After machining, both the frame and implanted wear insert undergo a surface hardening process together. The surface hardened wear insert has a greater surface hardness than the surface hardened frame and is better adapted to resist wear after repeated chambering of rounds. In one non-limiting example, the frame may be hard anodized aluminum and the wear insert hard anodized titanium.
