  • Patent number: 10907937
    Abstract: A quick disconnect clamping assembly for releaseably attaching an accessory to an elongate support such as a picatinny-style mounting rail comprising a clamp body with a mounting yoke that is adapted to slide over and receive the picatinny rail. The yoke includes a substantially rectangular base plate defining the central upper surface of the clamp body and includes a pair of parallel sidewalls extending upwardly therefrom. A pair of spaced slots formed in the inner surfaces of the sidewalls are adapted to receive a spring and a spring biased positioning ball acts to precisely position the clamping assembly on the mounting rail.

  • Patent number: 9175926
    Abstract: A firearm sight is disclosed herein. The firearm sight may include a housing, a main body assembly, and a sight assembly. The main body assembly may be operably attached to the housing, and the sight assembly may be operably attached to the main body assembly. Moreover, a deployment mechanism may be operable to deploy the main body assembly and the sight assembly from a closed position at least partially within the housing to an open position at least partially outside of the housing.

  • Patent number: 9046320
    Abstract: A firearm sight is disclosed herein. The firearm sight may include a main body assembly, a first plate assembly operably attached to the main body assembly, and a second plate assembly operably attached to the main body assembly opposite the first plate assembly. A sight assembly may be operably attached to the main body assembly between the first plate assembly and the second plate assembly. Moreover, a deployment mechanism may be operable to deploy the first plate assembly, the second plate assembly, and the sight assembly from a closed position to an open position.

  • Patent number: 8496212
    Abstract: A bipod comprises first and second tubular, spring-loaded telescopically extendable legs terminating distally in substantially triangular, claw-like end effectors. Each end effecter includes a substantially planar central segment having an upper surface defining a polygon resembling a truncated triangle with the first, second and third corners projecting downwardly at an acute angle. The first second and third downwardly projecting corner segments define substantially planar, triangular claw members, and so form a cup-shaped three pointed claw ideally well suited to grasp but not sink into any terrain surface.

  • Patent number: 7631455
    Abstract: A bipod mounting device for mounting a bipod support to a forearm stock of a firearm or other bipod mounted device permits a user or shooter to selectively allow panning (or altering the aim point along an azimuth), tilting (or altering the orientation of a device relative to a horizontal line) and canting (or orienting a device at a selected rotational orientation relative to an axis of rotation). The bipod includes lockable controls for selectively limiting panning, tilting and canting in a manner which lets the shooter or user easily respond to changing situations when in the field.

  • Patent number: 7526890
    Abstract: A rugged, adjustable optical alignment device well suited for use as a pistol rear sight is adapted for use in a dovetail, as is customarily seen on the slide of an automatic pistol. The sight assembly includes a rear notch, but could just as easily include a peep aperture or other optical alignment structure. The rear sight provides an easy click-detent adjusting mechanism for horizontal translation of the notch, as well as a second click-detent mechanism for vertical translation of the structure defining the notch, thereby providing adjustments for windage and elevation. A base hingedly supports a vertical tilt member. A horizontal slide member mounted on the rear of the vertrical tilt member is horizontally translatable by adjustment of a windage adjustment screw.

  • Patent number: 7222451
    Abstract: A quick disconnect clamping assembly for releaseably attaching an accessory such as a bipod to an elongate support such as a picatinny-style mounting rail comprises a clamp body with a mounting yoke that is adapted to slide over and receive the picatinny rail. The yoke includes a substantially rectangular base plate defining the central upper surface of a clamp body and includes a pair of parallel sidewalls extending upwardly therefrom. The base plate has, in one embodiment, first and second transverse bores for first and second substantially rectangular upwardly movable bolts actuable to project upwardly from the yoke base plate. The clamp body's first and second transverse bolts, when raised and aligned with the transverse grooves of the picatinny rail, are received in the spaced transverse grooves of the rail to attach the yoke to the rail.
