  • Patent number: 11293721
    Abstract: A scope mount assembly is provided including a scope mount having a reference axis and a level indicator rotatably joined with the scope mount. The level indicator can be rotatable from a stored mode, where a level indicator axis is transverse to the reference axis, to an extended mode, where the level indicator axis is transverse to the reference axis, and the level indicator projects laterally away from the reference axis. The assembly can include a first magnet that magnetically secures the level indicator in the stored mode, and a second magnet that magnetically secures the level indicator in the extended mode. A user rearward of the mount can view the laterally extending level indicator when the level indicator is in the extended mode, and optionally when the level indicator is in the stored mode, to confirm the level of the scope and any weapon to which it is mounted.

  • Patent number: 11262167
    Abstract: A quick mount for removably attaching an accessory to a longitudinal rail, the mount including a base having a first leg with a first undercut wall that engages a first longitudinal rail surface, a second leg opposite the first undercut wall, a retention plate rotatably mounted to the base adjacent the second leg and a bias element. The retention plate is operable in a secure mode in which the bias element urges the retention plate to rotate and engage a second undercut wall of the plate against a second longitudinal rail surface opposite the first surface and thereby clamp the mount to the rail. The retention plate is operable in a release mode where the second undercut wall disengages the second surface thereby releasing the mount from the rail. The mount can include a toggle lock to lock the plate in the secure mode. A related method is provided.

  • Publication number: 20210310765
    Abstract: A stock assembly and related method are provided. The stock assembly can include a base that can be joined with a weapon and a butt portion that movably extends from the base so the stock assembly can be adjusted in length. The stock can include an adjustment limiter configured to stop extension of the butt portion at a predetermined length, which can be set by a user to fit their stature. The butt portion can include a longitudinal axis and a limiter surface offset at an angle relative to the axis. The adjustment limiter can be a wedge that wedges against the limiter surface to set the stock assembly at the predetermined length, thereby automatically setting that length in a consistent and repeatable manner. A lock, separate from the adjustment limiter, can selectively lock the butt portion in a fixed position as or after the stock assembly attains the predetermined length.

  • Patent number: 10962324
    Abstract: A handguard and related method are provided. The handguard can include a clamp with opposing ramped surfaces, wedges engaging the ramped surfaces, and fasteners extending through the wedges and opposite sides of the handguard. Rotating the fasteners urges the wedges against the ramped surfaces to urge the clamp and a corresponding clamp element against a barrel to clamp the handguard to it. Where multiple fasteners are included, they can extend in opposite directions over the barrel, and can have reversed locking directions to distribute clamping forces to the barrel evenly. The clamp and wedges can prevent rotation of the handguard and provide parallel upward and downward movement. A fastener can extend through a wedge bore without engaging that wedge bore, while another fastener can threadably engage another wedge bore in the same wedge to provide horizontal wedge movement via rotation of the fastener.

  • Publication number: 20200318929
    Abstract: A support pod that supports a weapon in a firing position includes a support tube telescopingly joined with a leg having a longitudinal axis. A lock portion defines grooves downwardly angled relative to the longitudinal axis. A guide portion defines recesses downwardly angled relative to the axis. The recesses can be distal and separate from the grooves, and both optionally are downwardly spiraling. The leg is operable in a locked mode, in which a lock element is in a groove, and a guide element is in a corresponding recess, to set a first overall length of the support. The leg can operate in an adjustment mode in which the lock and guide element can transition out from the groove and recess, and can move to other respective grooves and recesses chosen by a user to set the pod at another overall length. A related method of use is provided.

  • Publication number: 20200278179
    Abstract: An optical device includes a toolless rezero system and/or a zero locking system. The rezero system can operate in a first mode in which a scale ring is non-rotatable relative to an axis. The ring can be manually moved to a second mode, where the ring is rotatable relative to the axis, so alphanumeric characters and bars can be moved about the axis to align a preselected zero element with a reference element and rezero the device. The zero locking system can include a locking cover button that is manually movable to automatically operate a locking ring in a first mode in which it rotatably couples the dial with an adjusting pin to move a reticle, and in a second mode in which it couples the adjustment dial to an immovable wheelbase so the dial is non-rotatable, and the reticle is locked in position. Related methods are provided.

  • Patent number: 10670369
    Abstract: A handguard assembly and related method are provided. The handguard assembly can include a fastener assembly that installs in a handguard bore of a handguard. The fastener assembly can include a fastener head including first threads threaded in a first direction, a shaft extending from the fastener head, the shaft including second threads threaded in a second direction opposite the first direction, and a lock tab threadably engaging the second threads, the lock tab including a tab head. When the fastener assembly is converted from a retracted mode to an extended mode, the tab head can wedge into a barrel nut groove to secure the handguard to the barrel nut thereby impairing the handguard from rotating and/or sliding relative to the barrel nut. The shaft can thread into the lock tab when the fastener assembly is installed relative to the groove, with the overall length of the fastener assembly increasing as the tab head moves in the groove.

  • Patent number: 10612880
    Abstract: An index mount for a firearm includes a mounting base, a connector flange and a selectively configurable paddle, joined with the connector flange, and configured to establish a resting surface to index a digit of a user relative to the firearm and consistently establish a particular grip relative to the firearm. The mount can include an indexing element that aligns and/or sets the paddle in first or second positions relative to the mounting base. The paddle can be configured with a forward cant and/or a rearward cant and can be adjusted to fit the user's preferences. The paddle can include an upper surface canted at an outward angle between 55° and 85°, inclusive. A related method of use is provided.

  • Patent number: 10393467
    Abstract: A dust cover for a firearm includes a panel, a hinge pin and a spring disposed around the hinge pin. The spring engages the hinge pin so that the spring is non-slidable relative to the hinge pin. The spring includes a first prong that engages the panel to bias the panel away from the ejection port. The spring includes a second prong, distal from the first prong, that is manually engageable by a user to slide the hinge pin within a panel passageway while the spring remains non-slidable relative to the hinge pin so as to remove a part of the hinge pin from a hole defined by the firearm and thereby free the dust cover for removal from the firearm. A related method of use is provided.

  • Publication number: 20190242677
    Abstract: A quick mount for removably attaching an accessory to a longitudinal rail, the mount including a base having a first leg with a first undercut wall that engages a first longitudinal rail surface, a second leg opposite the first undercut wall, a retention plate rotatably mounted to the base adjacent the second leg and a bias element. The retention plate is operable in a secure mode in which the bias element urges the retention plate to rotate and engage a second undercut wall of the plate against a second longitudinal rail surface opposite the first surface and thereby clamp the mount to the rail. The retention plate is operable in a release mode where the second undercut wall disengages the second surface thereby releasing the mount from the rail. The mount can include a toggle lock to lock the plate in the secure mode. A related method is provided.
