Abstract

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.

Abstract

A fault tolerant electromagnetic safety system for firearms comprises an electromagnetic actuator with movable rotating member operably interfaced with the firing mechanism. The actuator is controlled via a programmable microcontroller coupled to an electric power source onboard the firearm. A safety actuatable by a user operably interfaces with the actuator and is manually movable between actuated and standby positions. In a blocking position, the actuator engages and prevents the firing mechanism from moving to prevent discharging the firearm. The safety when in the standby position is configured to prevent the actuator from disengaging the firing mechanism. Upon the detecting movement of safety to the actuated position, the microcontroller moves the actuator to a non-blocking position allowing discharge of the firearm via a trigger pull. The safety when moving to the standby position may be configured to mechanically reset the actuator to the blocking position in event of an electronics failure.

Abstract

An electronic trigger system with safety mechanism for firearms includes a trigger unit comprising an electromagnetic actuator operably coupled to the firing mechanism and a programmable trigger mechanism microcontroller. The actuator is changeable between a non-powered unactuated position and powered actuated firing position via pulling both an outer trigger and inner safety trigger of the trigger unit. The actuator is operably interfaced with a movable firing component of the firing mechanism operable to discharge the firearm. In a blocking position of the safety trigger, the safety trigger is configured to block outer trigger movement which prevents energizing and actuating the electromagnetic actuator thereby preventing the firearm from discharging. Conversely in an unblocking position, the safety trigger allows outer trigger movement sufficient to discharge the firearm by either energizing the actuator when a pre-selected trigger pull force threshold is applied or applying sufficient trigger force to manually trip the actuator.

Abstract

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.

Abstract

An interruptible electronic trigger system for firearms includes a trigger unit comprising an electromagnetic actuator operably coupled to the firing mechanism and a programmable trigger microcontroller. The actuator is changeable between a non-powered unactuated position and powered actuated firing position. Upon detecting user initiated trigger activity, the trigger microcontroller transmits a shot initiated signal to an adaptive optics unit of a fire control targeting system mounted to the firearm when the trigger activity exceeds a preprogrammed trigger setpoint. A targeting microcontroller returns a shot authorization signal to the trigger microcontroller after performing ballistics computations based on sensor input and displaying a corrected reticle on the optics unit sight for user visual alignment with the target. Multiple trigger setpoints may be programmed to confirm continued intent to fire. The trigger microcontroller may deactivate the actuator and permit manual firing when preprogrammed maximum trigger force/displacement limits are exceeded.

Abstract

A firearm with dual-acting safety mechanism in one embodiment includes a slide movably carried by a frame, hammer, sear operable to hold the hammer in and release it from a cocked position, and firing mechanism including a trigger and trigger bar which collectively operate to actuate the sear to release the hammer. The safety mechanism includes right and left actuator levers coupled together and cooperating with a safety rocker. The safety rocker is operably interfaced with the trigger bar and pivotably movable between two positions. Moving either actuation lever to activate the safety mechanism rotates the safety rocker which simultaneously both blocks the trigger bar from movement and displaces the trigger bar to disengage the sear which can no longer be actuated via a trigger pull. In one embodiment, the safety mechanism is further operable to lock the slide in the closed breech position when the safety is activated.

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.

Abstract

A hybrid magnetically variable firing system for a firearm includes a trigger mechanism configured to allow a user to selectively adjust the trigger pull force-displacement profile. In a closed magnetic flux loop configuration, the trigger mechanism includes a selectively energizable electromagnetic and mechanical biasing member providing a static holding torque which creates resistance opposing movement of the trigger. Energizing the electromagnetic at a user-preselected point during the trigger pull event creates a magnetic force opposing the static holding torque, which dynamically changes the trigger pull force required to discharge the firearm. The electromagnetic assists the user in completing the trigger pull thereby creating an adjustable lighter trigger pull. In one embodiment, the electromagnet is energized when the actual trigger pull force applied or trigger displacement reaches a corresponding trigger setpoint preprogrammed into a control circuit. A microcontroller may control operation of the trigger mechanism.

Abstract

An electromagnetic actuator in one embodiment 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 on the yoke 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 blocking applications.

Abstract

A pump action firearm with bolt slide locking mechanism includes a receiver, a barrel assembly coupled by the receiver, and a bolt slide slideably disposed in the receiver for movement between rearward open breech and forward closed breech positions. A slide lock pivotably mounted to the bolt slide about a pivot axis is selectively engageable with an interference surface on the receiver. When the firearm is fired via a trigger pull, a rotatable hammer strikes and actuates the slide lock. The slide lock rotates from a locked position engaged with the interference surface to prevent the slide from moving out of the closed breech position, to an unlocked position disengaging the interference surface. This allows the slide to be manually moved to the open breech position for cycling the action. A manual actuator is provided for unlocking the slide lock absent a trigger pull.

Abstract

A bolt assembly for firearms utilizing a blowback type operating system. The bolt assembly comprises a non-rotatable bolt slideably disposed in the receiver for forward and rearward movement and a dead blow weight assembly slideably coupled to the bolt. The dead blow weight assembly may be two-piece comprising a dead blow weight and dead blow top member. These parts are separate components movable independently of each other, but functionally interacting and cooperating under recoil after discharging the firearm to eject a spent cartridge casing and chamber a new cartridge as the action is reset. When the firearm discharged, a two-stage felt recoil force is generated by this mechanism, thereby advantageously producing peak forces which are less in magnitude than the single strong felt recoil force experienced by users with conventional one-piece bolt used in many blowback type firearms.

Abstract

A variable barrel camming system for a firearm includes a linearly reciprocating slide supported by a frame and a barrel removably coupled to the slide for movement therewith. A cam slot on the barrel slideably engages a cam pin mounted transversely in the frame. The slot includes a cam track surface having multiple angles and contours designed to control the motion and orientation of the barrel. When the firearm is discharged, the slide and barrel initially move rearward together under recoil forces generated. The pin slides forward in the slot over the cam track surface which is configured to rotate and uncouple the barrel from the slide which continues rearward alone. The cam track surface has a varying cam profile selected to gradually dissipate the kinetic energy of the barrel/slide unit in a controlled manner, thereby reducing the felt recoil imparted to a user compared to conventional cam systems.

Abstract

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.

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.

A chamber reinforcement for composite firearm barrel and method for forming the same. In one embodiment, the barrel includes an inner tube defining a bore that provides a bullet path and an outer sleeve preferably made of a material lighter in weight than the tube. In some embodiments, the inner tube is made of a material that preferably has a greater density and strength than the outer sleeve. The reinforcement in one embodiment may be in the form of an end cap disposed on a portion of the sleeve. The reinforcement preferably is made of a material comparable to the inner tube in density and strength to reinforce the area where a chamber is formed for receiving a cartridge. In the preferred fabrication, the reinforcement, tube, and sleeve are forged together to provide a strong and unitary structure for withstanding combustion pressures and forces associated with discharging the firearm.

Abstract

A pistol including a loaded chamber indicator to identify the presence of a cartridge loaded in the firing chamber. The pistol may generally include a barrel, a receiver attached to the barrel thereby defining a barrel-receiver assembly, and a chamber associated with the barrel-receiver assembly. An indicating element is provided which in one embodiment may be pivotally mounted in the barrel-receiver assembly. The indicating element is displaceable in response to contact by the cartridge from a first position which may in one embodiment correspond to an absence of a cartridge loaded in the chamber, to a second position which may in one embodiment correspond to a presence of a cartridge loaded in the chamber. A biasing member, such as a spring, may be provided to bias the indicating element towards the first position. In one embodiment, the indicating element protrudes outwards from the exterior of the pistol in response to contact by the cartridge rim to provide a visual and tactile indication of a loaded chamber condition to a user of the pistol.
