Abstract: A fire control group system for a firearm includes a trigger that includes a trigger base, a trigger extension extending from the trigger base, and an over-travel member coupled to the trigger base at a front end thereof. The trigger base has a sear hook extending therefrom and defining a recess and a transverse bore intersecting the recess. The over-travel member has a contact surface and is moveable relative to the trigger base such that a distance in a vertical direction between the contact surface and the trigger base is adjustable.

Abstract: A multipurpose tool that includes a handle and a body. The body has an opening that extends through the body and has a first set of pins that are removably connected to the body. The first set of pins are arranged along and adjacent to at least a portion of the perimeter of the opening and project away from the first side of the body. The multipurpose tool also includes a modular hammer and other tool features, some of which are configured to operate on a firearm for its disassembly and reassembly.

Abstract: 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.
