Patent number: 11402175Abstract: An electronic indicator on a see-through optical scope indicates whether an optical system is canted. The indicator may include illuminable visual indicators positioned on opposite sides of a field of view through the optical scope. The indicator may be visual, haptic, or aural. The visual indicator may include one or more LEDs positioned on the periphery of the field of view, and may be optically coupled to an appropriate position on the face of the reticle using a suitable waveguide. The LEDs are coupled to a microprocessor which is, in turn, coupled to a solid-state electronic inclinometer that is incorporated into the internal structure of the optical system. The microprocessor is configured to selectively illuminate one or more of the visual indicators based on the output of the inclinometer, thereby indicating how the reticle is canted, if at all.Type: GrantFiled: November 19, 2019Date of Patent: August 2, 2022Assignee: SIG SAUER, INC.Inventors: Andrew W.

Patent number: 11365952Abstract: A firearm stock with adjustable length of pull and/or comb height is disclosed. In one example, a butt plate assembly includes a tongue defining top and bottom chamfered outside edges. A stock body defines top and bottom chamfered inside edges along a slot opening. Moving a locking assembly to a locked position draws the chamfered outside edges on the tongue against the chamfered inside edges along the slot opening. A locking plate can be used between the fastener and the tongue. In another example, an adjustable comb assembly includes a cheek plate with posts received in post openings that extend into the stock body. A locking lever is coupled to a fastener that extends laterally through the stock body. Moving the lever to the locked position draws together opposite sides of the stock body to constrain the post openings, thereby retaining the position of the comb.Type: GrantFiled: August 14, 2020Date of Patent: June 21, 2022Assignee: Sig Sauer, Inc.Inventors: David B.

Patent number: 11326852Abstract: A hinge joint includes first and second hinge leaves pivotably mounted on a hinge pin, where the hinge joint is operable between open and closed positions. The hinge joint has a locking mechanism that prevents opening the hinge joint from a closed position until the locking mechanism is moved to the unlocked position. In one example, the locking mechanism includes a plunger retained in the hinge pin. When the plunger is depressed, one or more protrusions can move from a blocking position to a non-blocking position. In some embodiments, the locking mechanism must be moved to the unlocked position prior to opening the hinge joint. The locking mechanism may be used alone or in combination with engagement structures between the first and second hinge leaves. The hinge joint can be part of a folding rifle stock assembly or other hinged assembly.Type: GrantFiled: October 16, 2020Date of Patent: May 10, 2022Assignee: Sig Sauer, Inc.Inventors: Luke E.

Patent number: 11280571Abstract: A flash hider is configured to reduce a firearm's visible signature. The flash hider extends along a central axis from a proximal end to a distal end. The proximal end defines a central opening to an expanding central volume of a first flash hider portion. One or more outer volumes are located radially outside of the central volume and can be part of first and/or second flash hider portions. When the outer volumes are part of the first flash hider portion, the outer volumes can communicate with the central volume. Optionally, a second flash hider portion includes one or more gas passageways located radially outside of the central volume. For example, gas passageways are interspersed circumferentially with outer volumes of the first flash hider portion, where the gas passageways are isolated from first flash hider portion and receive gas flows via vent openings in the outer wall.Type: GrantFiled: November 20, 2020Date of Patent: March 22, 2022Assignee: Sig Sauer, Inc.Inventors: Evan Miller, Krzysztof J.

When the striker is in the cocked position, the first sear is movable from an engaged position to a disengaged position in response to moving the trigger from the resting position to the pulled position. A second sear is movable from a blocking position to a non-blocking position in response to moving the trigger from the resting position to the pulled position. When the trigger is in the resting position, the second sear is positioned to halt forward motion of the striker from the cocked position to the fire position.Type: GrantFiled: February 22, 2021Date of Patent: March 15, 2022Assignee: SIG SAUER, INC.Inventors: Krzysztof J.

Patent number: 11248862Abstract: A charging handle for a firearm includes a longitudinal body with a proximal end portion and a distal end portion. The proximal end portion includes at least one latch lever operable between a first position and a second position, the latch lever including a blocking plate. Moving the handle from the first position to the second position moves the blocking plate from a blocking position to a non-blocking position. The charging handle can be used with a firearm that includes a protrusion extending up from the rear-end portion of the lower receiver or from the recoil assembly. In the blocking position, the blocking plate is aligned with the protrusion and prevents the charging handle from rearward movement. When the blocking plate is in the non-blocking position, the blocking plate clears the protrusion to permit the charging handle to be drawn rearward.Type: GrantFiled: December 1, 2020Date of Patent: February 15, 2022Assignee: SIG SAUER, INC.Inventors: Kenneth Samuel Frazier, Bryan Charles Dustin
