  • Patent number: 10126095
    Abstract: A handguard for attachment to a standard AR-pattern firearm upper receiver. A barrel nut has a substantially cylindrical outer surface with an annular groove. A handguard sleeve has an end opening configured to slide over the outer surface of the barrel nut, a channel with a bottom guide surface, and a substantially transverse cross bore positioned to at least partially intersect the end opening to align with the annular groove when the handguard sleeve is positioned on the barrel nut. A pair of wedge members are sized to be received in the channel and connected by at least one wedge fastener configured to adjustably move the wedge members together. When the barrel nut is attached to an upper receiver, the handguard sleeve is attached to the upper receiver by sliding the end opening over the barrel nut and inserting a cross bolt fastener in the cross bore and a portion of the annular groove.

  • Patent number: 9863740
    Abstract: A sight mechanism for firearms such as pistols, rifles and the like. The sight mechanism includes a sight member that has a rear sight that is vertically adjusted. The sight member can be mounted on a vertically moveable member that has a fixing member that sets the vertical position of the sight member. The vertically moveable member may, without limitation, be a pivoting member. The sight mechanism includes magnets that bias the vertical member against the fixing member so that the magnets maintain the sight at the vertical position defined by the fixing member.

  • Patent number: 9835394
    Abstract: A charging handle having a base and a substantially perpendicularly-oriented cross-member. The cross-member is configured to be received longitudinally within an upper receiver for a firearm with the base being positioned fully forward of the upper receiver. The charging handle further includes a spring-biased charging handle latch that pivots about a fulcrum pin. The charging handle latch has an upper arm and a lower arm. The upper arm includes an angled surface that, when engaged, contacts an upper edge of a charging handle latch pocket within a side of the upper receiver. The lower arm is biased by a compression spring that is positioned within a bore of the base. When engaged, the angled surface of the upper arm is retained within the latch pocket of the upper receiver and creates an angle relative to an imaginary centerline of the charging handle cross-member.
