Abstract: 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.

Abstract: A target dot sight includes a target illumination sensor that senses the amount of illumination at a target, rather than merely sensing the ambient sight of the entire operating environment. Then, based on the sensed target illumination, the target dot sight may automatically compensate for the brightness of the target.

Abstract: A brace assembly is configured for use with a longitudinal support of a firearm, such as a cylindrical bar or receiver extension. The assembly includes a brace body with a first or lower body member and a second or upper body member. The body members are configured to engage opposite surfaces of the longitudinal support. A brace portion can be attached to the brace body. In one example, a mounting post extends rearwardly from the brace body and the brace portion includes left and right brace members each having an upper end portion configured to attach to and pivot about the mounting post.

Abstract: 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.
