A holster system for receiving and releasably retaining a handgun with or without a reflex sight mounted thereon. The holster body comprises a pair of opposing side wall portions and an upper wall portion. The holster body may define a rear accessory sight opening for receiving the handgun with the reflex sight attached thereto. The holster system may include a first rear sight cover selectively and robustly coupleable to the holster body so as to cover the rear accessory sight opening when a handgun with conventional sights extending upwardly about ⅜ of an inch or less mounted thereto is used in conjunction with the holster system. The holster system may also include a second rear sight cover selectively coupleable to the holster body so as to cover the sight opening when a handgun with a reflex sight mounted thereto is used in conjunction with the holster system.

A firearm attachment member includes a firearm mounting structure which includes a receiver support shelf for supporting thereon a receiver of a firearm. The firearm attachment member includes left and right halves, arranged for securing the firearm between the left and right halves, each of the left and right halves extending along a longitudinal axis corresponding to a longitudinal firing axis of the firearm. One of the left and right halves pivots in azimuth with respect to the longitudinal axis about a firearm attachment member pivot located rearward of the firearm mounting structure. Each of the left and right halves includes a forward fastening flange configured to be mounted below the receiver and in front of the trigger guard of the firearm. The forward fastening flanges are fastened together with a fastener.

A charging handle accessory has an upper portion with a pair of parallel, spaced-apart sidewalls connected at their upper extent. The upper portion is configured to be assembled over an upper portion of the charging slide. A lower portion has a pair of parallel, spaced-apart sidewalls connected at one end. Each of the sidewalls of the lower portion has a lip configured to engage a lower extent of the charging slide. A sliding connection is provided at the lower extent of the upper portion and the upper extent of the lower portion, wherein the upper and lower portions are coupled together in sliding relation. A fastener extends between the upper and lower portions to secure the upper and lower portions against sliding relative to one another and secure them on the charging slide of the firearm.

An optical sight, system, and method for a firearm. The optical sight includes a housing including a base. A first support and a second support extend from the base. A top support extends between the first support and the second support. The top support extends over an optical element and includes a surface adjacent to the optical element. A second cross member defining one or more openings between the first cross member and the first and second supports. An optical element supported by said housing between said first support and said second support. A reticle is displayed on the optical element.

A brace assembly includes a firearm attachment member to which a pivot arm is pivotally attached at a pivot. The pivot arm includes a brace member at an end opposite to the pivot. The firearm attachment member includes firearm mounting structure which includes a receiver support shelf for supporting thereon a receiver of a firearm, and a distal abutment against which a forward end of a receiver and/or a slide of the firearm is abuttable.

In one example, the disclosure relates to adjustable flip up sight assembly that can be adjusted vertically and laterally in particular, for an automatic firearm, comprising a front sight support element that is supported by an axle on a mount, in particular such that they can pivot thereon, wherein the front sight support element has an adjustment element supported on a spring element and releasably connected to a front sight, which contains a keyhole type opening through which the axle is inserted, wherein the adjustment element can be moved in relation to the axle against the spring force between two positions inside the front sight support element such that the keyhole opening prevents a lateral movement of the front sight support element along the axle when engaged with the axle, and allows the lateral adjustment of the front sight support element in a released position.

An optical sight and system. The optical sight includes a housing including a base. A first support and a and a second support extend from the base. A top support extends between the first support and the second support. The top support extends over an optical element and includes a surface adjacent to the optical element. The top support of the housing defines at least one opening extending above a portion of the optical element. The optical element is supported by the housing between the base, the first support, and the second support.
