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.

ELECTROMAGNETIC FIRING SYSTEM FOR FIREARM WITH INTERRUPTABLE TRIGGER CONTROL
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.

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.

A bolt hold open assembly for a rotary magazine may include a bolt hold open lever movable to a locked position to inhibit forward motion of the bolt after firing the last round of ammunition. The bolt hold open lever may be moved to the locked position by a bolt hold open riser that is activated by a paddle movable with the rotor assembly of the rotary magazine.
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.

A modular magazine well insert system accepts and latches different types of magazines including front and side catch styles. The system includes a plurality of magazine well inserts each having a common mounting interface which interfaces with a mounting feature formed in a receptacle of the firearm stock. The inserts may have a common basic configuration with some different features adapted for use with different magazine catch features, such as latching levers for front catch magazines or lateral apertures to access side catch magazines. A universal latch stud slideably mounted in the stock comprises features which cooperate with each of the magazine well inserts to retain and release both catch styles of magazines in the insert.
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.

Dynamic variable force trigger mechanism for firearms
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.
An adjustable stock for a firearm includes a longitudinally-extending chassis supporting a receiver, a butt pad assembly adjustable in longitudinal position for varying the length of pull, and a cheek rest. The cheek rest is adjustable in longitudinal and vertical positions. A triple-acting locking mechanism having locked and unlocked positions is operable to simultaneously lock the butt pad assembly in longitudinal position and the cheek rest in both longitudinal and vertical positions. The locking mechanism may be a cam lever assembly in non-limiting examples having a pivotable cam lever operable to simultaneously unlock or lock the butt pad assembly and cheek rest, thereby providing a single point of operation for making all the foregoing stock adjustments.

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.

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.
