Abrégé

An illuminated reflex optical sighting system integrated directly into a firearm includes a lighting module comprising an illumination source mounted to a body of the firearm at a discrete first mounting location, an optical lens assembly mounted to the body of the firearm at a discrete second location spatially distanced from the first location, and a power source operably coupled to the illumination source. The illumination source is configured and operable to project a reticle onto a lens of the lens assembly for use in aiming the firearm. The illumination source and lens assembly are separately mounted to and independently removable from the body of the firearm thereby providing a low profile sighting system which substantially retains the aspects of the original firearm. The illumination source, power source, and lighting control circuitry may be housed inside the metal rear sight of the firearm in one embodiment.

Abrégé

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.

Abrégé

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.

Abrégé

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.

Abrégé

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.

Abrégé

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.

Abrégé

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.

Abrégé

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.

Abrégé

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.

Abrégé

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.

Abrégé

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.

Abrégé

A magazine for a firearm comprises a tubular body defining a cavity for holding cartridges, a spring, and a follower biased by the spring for dispensing cartridges from the magazine. In one embodiment, the follower includes lateral guide projections which engage corresponding slots in the sidewalls of the magazine body. This guides movement of the follower and maintains a substantial horizontal orientation as it travels vertically in the magazine by preventing twisting/tilting which might otherwise create potential cartridge feeding jams. In some embodiments, the follower may include front and rear stabilizer projections to further guide movement of the follower in the magazine cavity.

Abrégé

A user-adjustable recoil reduction system for a firearm includes a buttstock and a butt pad assembly movably mounted to the buttstock. A spring is disposed in the buttstock which is acted on by opposing front and rear spring guides. A preload adjustment screw is rotatably coupled to the butt pad assembly which engages the rear spring guide. Rotating the screw in opposing directions alternatingly advances or retracts the rear spring guide in the buttstock. Advancing the rear spring guide compresses the spring to set a first spring preload condition and retracting the rear spring guide relaxes the spring to set a second spring preload condition different than the first condition. The spring preload conditions may be selected to match firing light or heavy type ammunition shell loads. In one embodiment, the adjustment screw is accessible for adjusting the preload without removing the butt pad assembly from the buttstock.
