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 height-adjustable optics mount includes a lower base attachable to the firearm including an angled platform having a plurality of male guiding teeth and located on the lower base; and an upper base which is operable between a slidable position where the upper base is sliding along the plurality of the male guiding teeth and a static position where the upper base is affixed on at least one of the plurality of male guiding teeth.

Disclosed are implementations of a pivot mount for an optical sighting device. A sight support member of the pivot mount is moveable between an operative position, wherein an optical sighting device can be used to sight the firearm on a target, and an inoperative position, wherein the optical sighting device is positioned below, and vertically offset from, the operative position.

A apparatus implementable on a firearm includes a handguard assembly which is configured to at least partially surround a barrel of the firearm when the handguard is installed on the firearm. The handguard includes at least first and second physical features such that: (a) the first physical feature is configured to accommodate mounting of an accessory of the firearm on the handguard, and (b) the second physical feature is configured to secure a cable of the accessory onto the handguard.

An apparatus and method for modifying a handgun to accept an optical sight comprises a modified slide mechanism adapted to include a flat recessed rear section configured to receive an adapter plate for mounting an optical sight. Various embodiments include modified internal components used to replace stock components what will no longer fit within the modified profile of the slide mechanism. Replacement of the slide mechanism and associated internal components will allow a user to add an optical sight to an existing handgun.

A firearm optics mount is configured to position an optic device on a firearm in a position offset from vertical alignment above the barrel when the firearm is in the vertical position. The canted mount includes a base, a support, and an optic mount at the end of the support. The support is configured to offset the optic between 5 and 30 degrees from vertical alignment with the barrel when the firearm is vertically positioned. The support may be configured to offset the optic between 12 and 22 degrees. The base of the mount may include a rear sight. The optic mounted to the firearm via the canted mount may be a primary or only optic of the firearm. The mount may vertically align a bullet drop feature of an optic with the centerline of the barrel when the firearm is canted to position the optic vertically above the barrel.

A mounting system securing a firearm sight to a firearm accessory rail includes a clamp with a downwardly open rail cavity for slidably engaging the rail. The sight is matched to a plate with pins that correspond to the sockets on the bottom of the sight, and the plate has sockets that correspond to pins on a base that contacts the rail. The clamp extends through the base and plate allowing the sight to be secured to the clamp. Securing the sigh to the clamp compresses the base, plate, and sight toward the rail, placing the system in tension to hold the sight to the firearm.

Improved firearms including one or more of a removable and/or interchangeable top cover, an improved extractor mechanism, a striker safety mechanism with a direct trigger interface, a sear with direct striker interface, and/or a striker with integral striker spring retention features.

An accessory mount system for connection to a rear sight block (RSB) of a Kalashnikov pattern firearm includes a locking insert that has a projection which extends in a first direction. The projection is adapted to be received within a first recess of the RSB for connection thereto. An adapter body is connected to the locking insert and has a projection that extends in a second direction opposite the first direction. The projection of the adapter body is adapted to be received within a second recess of the RSB for connection thereto. A mount body is connected to the adapter body and has an accessory interface which is adapted to connect to an accessory. An adapter body is secured with a push-pivot pin securely wedging the projection of the adapter against an internal wall of the RSB.
