Implementations of an adapter plate system for mounting optical sights on a pistol are provided. An example adapter plate system for mounting optical sights on a pistol comprises: a pistol slide, the pistol slide includes an adapter interface, the adapter interface comprising a bottom surface that extends between a first end wall and a second end wall; and an adapter plate, the adapter plate includes a mounting surface on a top side thereof, the mounting surface is configured so that an optical sight can be attached thereto. The adapter plate is configured so that it can be rotated into position between the first end wall and the second end wall of the adapter interface.

A multi-accessory mount assembly for use with a firearm, and methods for coupling the assembly to the firearm are provided. The assembly may include a proximal portion having a lower surface configured to be removably coupled to the firearm and an upper surface configured to be removably coupled to a sub mount. The sub mount may be configured to be removably coupled to a first firearm accessory, e.g., an optic scope, a red dot sight, a reflex sight, a night vision monocular or scope, or a magnifier. The assembly further may include a distal portion extending distally from the proximal portion via a neck portion, such that the distal portion is elevated higher than the proximal portion. An upper surface of the distal portion may be configured to be removably coupled to a second firearm accessory, e.g., an infrared laser or a night vision monocular or scope.

Implementations of an optical sight mounting system are provided. An example optical sight mounting system comprises an optical sight having a base that can be secured to a pistol slide having an adapter interface. The base of the optical sight is configured so that it can be rotated into position within the adapter interface. In this way, the optical sight can be mounted on a pistol and used to aim. Another example optical sight mounting system comprises an optical sight having a base that can be secured to an adapter interface of an optical sight mount. The base of the optical sight is configured so that it can be rotated into position within the adapter interface. The optical sight mount is configured to releasable engage a mounting interface of a firearm (e.g., a MIL-STD-1913 rail). In this way, the optical sight can be positioned on a firearm (e.g., a rifle) and used to aim.

Some embodiments of the present invention provide a mounting apparatus for supporting a device such as a night vision (30) device comprises a clamp (60) having an opening for receiving an end portion of the night vision device. The clamp has a concave inner surface (68) when viewed in cross-section and a longitudinal axis (54). An insert (70) is configured to locate within the opening of the clamp (60). The insert (70) has an inner surface (72) for locating against the night vision device (30), or the insert (70) being integrated with the night vision device (30), the insert (70) having a convex outer surface (78) when viewed in cross-section, wherein the convex outer surface (78) of the insert is movable across the concave inner surface (68) of the clamp to allow adjustment of a position of the insert (70) relative to the clamp (60) about an x axis and/or a y axis which are mutually perpendicular to the longitudinal axis (54). The clamp (60) is configured to secure the insert (70) in a selected position.
