Implementations of an adapter plate system for mounting optical sights on a pistol are provided. In general, the adapter plate system comprises an adapter plate configured so that an optical sight can be mounted thereon and a pistol slide having an adapter interface configured to receive the adapter plate. The adapter plate can be rotated into position between end walls of the adaper interface. An example adapter interface may include a pivot boss that extends up from the bottom surface thereof. The pivot boss is positioned to be received within a pivot bore located in the underside of an example adapter plate.

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

Disclosed is a scope mount for a firearm that can be used for firing different types of ammunition without having to re-zero the scope when switching from one type of ammunition to another. The scope mount can include a base and a chassis pivotally mounted to the base. The chassis adjusts both elevation and windage alignments of the scope with respect to the base. Also disclosed is a method of operating a scope assembly mounted to a firearm, including the steps of setting a handle of the scope mount to a rested position corresponding to a first type of ammunition, zeroing the scope when the handle is in the rested position; moving the handle to an engaged position corresponding to a second type of ammunition different from the first type of ammunition; and zeroing the scope when the handle is in the engaged position.

Implementations of an adapter plate system for mounting optical sights on a pistol are provided. The adapter plate system may comprise an adapter plate configured so that an optical sight can be mounted thereon, a pistol slide having an adapter interface configured to receive the adapter plate, and, in some implementations, a slide cover plate configured to prevent the adapter plate from rotating while it is positioned within the adapter interface. The adapter plate is configured so that it can be rotated into position between the end walls of the adapter interface. In some implementations, the adapter interface of the pistol slide may comprise a bottom surface having a pivot boss and a rotation stop extending therefrom. The pivot boss and the rotation stop are positioned on the bottom surface of the adapter interface so they are received within a pivot bore and a guide channel, respectively, in the underside of the adapter plate.

A scope mount with a rectangular plate with a top channel that extends to an upper portion of the rectangular plate, a bottom channel that is perpendicular to the top channel, a hole for a screw to be inserted through to secure the plate to a Daisy Red Ryder BB Gun to allow an optic sight to be mounted to the Daisy Red Ryder BB Gun.

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.

A scope mount with a rectangular plate with a top channel that extends to an upper portion of the rectangular plate, a bottom channel that is perpendicular to the top channel, a hole for a screw to be inserted through to secure the plate to a Daisy Red Ryder BB Gun to allow an optic sight to be mounted to the Daisy Red Ryder BB Gun.

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.

A quick-attachment/quick-release firearm accessory mounting assembly releasably and rotatably attached to a firearm rail, chassis, or handgun slide to receive any of a number of different accessories, such as, a telescopic sight, reflector sight, laser sight, night vision sight, thermal scope, range finder, and other secondary instruments. The mounting assembly is in the form of an adaptor plate having attachment structures for receiving the accessory on a top surface, and securing to the firearm structure on a bottom surface. The firearm is modified to receive the adaptor plate, the firearm frame having a recess portion with a center protrusion in rotatable communication with a center aperture in the adaptor plate, and having grooves or slots formed at each end of the recess portion to receive flanges at each end of the adaptor plate upon rotation.

An improved device for enabling a user to quickly and securely attach and detach an accessory (e.g., a scope, light, bayonet, etc.) to the Picatinny or tactical rail of a firearm. In a preferred embodiment of the present invention, the device comprises a lower portion, an upper portion and a locking mechanism. The device is relatively inexpensive to manufacture and safe and easy to use.
