Rearward Patents (Class 42/16)
  • Patent number: 10458731
    Abstract: A bolt for a bolt-action firearm in one embodiment is movably disposed in a receiver between forward closed breech and rearward open breech axial positions. The bolt includes an operating handle and plurality of bolt lugs arranged to selectively engage locking lugs in the firearm. The bolt is rotatable between locked and unlocked breech positions when in the closed breech position. The bolt body has a dimensionally reduced middle section with unique configuration adapted to allow the bolt to rotate when closed without interference from the magazine feed lips. Using this design, the bolt may include three bolt lugs in one embodiment for secure lockup and minimal angular rotation between the locked and unlocked breech positions. The bolt is usable with both single and double stack box type magazines with one of the bolt lugs operating to reliably strip cartridges from either type magazine.

  • Patent number: 10422595
    Abstract: The present device is a shortened recoil system designed to replace the AR-15 type recoil system, comprising the standard recoil systems of many commonly used rifles including the AR-10, AR-15, M-16 and M-4. This shortened recoil system removes or replaces the parts of the traditional recoil system located in the stocks of these rifles and place the entire recoil system within the receiver, while maintaining the alignment of the recoil system with the barrel of the rifle. A major advantage of the present system is that it allows the rifle to be fired with a folded stock or even with no stock at all, as no part of the present recoil system is located within the stock.

  • Patent number: 10401101
    Abstract: A firearm includes a frame, a slide assembly, an actuator, a bolt assembly, and an adjuster. The slide assembly includes a threaded bore, the slide assembly releasably and slidably coupled to the frame. The actuator includes a body and an extension, the extension protruding from the body. The bolt assembly includes a catch. The adjuster includes a first end, a second end, and a plurality of threads. The first end includes an interface configured to accommodate the extension of the actuator. The plurality of threads are disposed between the first end and the second end. The plurality of threads are configured to interface with the threaded bore of the slide assembly such that rotation of the adjuster within the threaded bore of the slide assembly by the actuator translates the bolt assembly and thereby facilitates firing ammunition having different casing lengths.

  • Patent number: 10401102
    Abstract: A device for converting a semiautomatic firearm to a non-semiautomatic firearm. The device includes a bolt stop lever pivotally attachable to a receiver of a firearm, a spring configured to be installed in contact with the bolt stop lever and a firearm receiver such that the spring exerts a force on the bolt stop lever to retain the bolt stop lever in a first position, and, a bolt release mechanism operatively coupleable to the bolt stop lever and configured to pivot the bolt stop lever against the force of the spring into a second position. The bolt release mechanism is operatively decoupled from the bolt stop lever when the bolt stop lever reaches the second position. When in the first position the bolt stop lever restricts motion of a bolt of the firearm, and when in the second position, the bolt stop lever permits motion of the firearm bolt.

  • Patent number: 10401103
    Abstract: The present invention relates to firearms and, more particularly, to automatic or semiautomatic firearms. In a first embodiment, the gas block of the firearm is tightly bound with the upper receiver rather than the barrel, and the receiver serves as a dampening element for gas block vibrations during shooting such that the impact on the barrel is significantly reduced. Fasteners and barrel nuts are used to rigidly position the gas block relative to the upper receiver to best reduce the impact on the barrel. In another embodiment the gas block is attached both to the upper receiver and to the barrel using a support element. Such fixation of the gas block prevents rotation of the firearm and further decreases vibrations of the barrel. In yet another embodiment, the firearm fits interchangeable magazine wells to change the caliber of the firearm.

  • Patent number: 10378839
    Abstract: The present low pressure bolt carrier group is configured to maximize the axial force component, and minimize the radial force component, applied to both the bolt carrier and the bolt under low-pressure gas conditions, so that the two separate with greater acceleration and under greater force than a standard bolt carrier group when firing low-pressure ammunition. Thus, the present low-pressure bolt carrier group effectively and completely ejects the spent case and chambers the next round. These and other benefits are provided by the present low-pressure bolt carrier group comprising one or more of an increased piston bore diameter, an increased piston diameter, an increased flatness of the piston surface in the radial plane, and an increased stroke length of the piston by lengthening the cam pin slot. Therefore, the present low-pressure bolt carrier group solves long-persisting problems with standard bolt carrier groups when using low-pressure rounds.

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.

  • Patent number: 10247497
    Abstract: A firearm gas redirection assembly directionally directs discharged gases from a barrel towards a bolt frame, and uses the energy from discharged gases to force a bolt rearwardly in an action. The barrel has an elongated body, an inner barrel sidewall, an outer barrel sidewall, a rear end, and a forward end. The forward end of barrel forms gas vents. The barrel is fixed motionless on the frame of the weapon. A jet nozzle concentrically couples around the barrel and integrates with a bolt frame. The jet nozzle has inner and outer jet sidewalls and a jet nozzle edge. The inner jet sidewall and outer barrel sidewall form a gas space that is in communication with the bolt frame. Discharge of firearm forces high velocity gas through gas vents that form in the barrel, through gas space, and finally against the jet nozzle edge. This forces bolt frame rearwardly.

  • Patent number: 10151544
    Abstract: A bolt carrier for a firearm, including lugs on the first end to engage corresponding lugs of a barrel receiver/extension. The bolt carrier includes a cam slot within which a cam pin from a bolt is constrained to travel along a cam slot path during rotational and translational movement of the bolt. The cam slot defines (1) a first cam slot means for constraining motion of the cam pin and the bolt during engagement or disengagement of the lugs of the bolt and the corresponding lugs of the barrel receiver or extension; (2) a second cam slot means for imparting rotational movement to the cam pin and bolt during linear movement of the bolt carrier; and (3) a third cam slot means for constraining motion of the cam pin at an end of a rearward travel of the bolt and bolt carrier during an ejection cycle. The combination of the first, second, and third cam slot means yields an extension of the unlocking by over 10% and a delay of the actual unlock of the bolt by over 5% relative to TDP.

  • Patent number: 9874417
    Abstract: A firing control system for a firearm includes a frame, a barrel with chamber configured for holding a cartridge, a spring-biased striker movable forward and rearward in a linear path along a longitudinal axis, a trigger mechanism comprising a trigger, a pivotable sear, a pivotable sear connector engaged with the sear, a sear pivotable connector blocker engaged with the sear connector, and a linearly movable sear connector actuator engageable with and operable to move the sear connector and sear connector blocker. Pulling the trigger slides the sear connector actuator which in sequence engages and rotates the sear connector blocker to disengage the sear connector, and engage and rotate the sear connector to disengage the sear and release the striker from a cocked position to discharge the firearm. In the absence of a trigger pull, the sear connector blocker remains engaged with the sear connector to prevent firing the firearm.
