A method of installing a safety selector in a firearm includes inserting the safety selector into an opening in the firearm, aligning a hole extending through the safety selector with a cavity extending transversely from the opening, inserting a spring through the hole and into the cavity, inserting a detent plunger through the hole and at least partially into the cavity, thereby compressing the spring, and moving the safety selector within the opening transversely to the cavity so as to capture the detent plunger at least partially within the cavity. The invention also encompasses a method of removing the safety selector.

A firearm safety system and method is described herein. The system may include a tracking system, a smart firearm and/or a smart magazine, and a smart tracking unit. The tracking system is in communication with satellites that monitor specific locations, a smart firearm and a portable electronic device. The tracking system includes an internal geographical database of specific monitored locations. The smart firearm includes a microprocessor and a receiver. The motor operates in response to a signal received, which may indicate that the firearm is approaching a no gun safety zone, whereby the signal causes the microprocessor to operate the automatic safety lock to prevent the apparatus from operating. The receiver monitors signals and receives location data from the satellites. The method of operating a smart firearm includes receiving a signal at the at least one receiver and responding to the signal by locking the automatic safety lock.

A magazine well for a firearm having an angled spine receiving portion. A charging handle for a firearm having latch that extends below a bottom surface of a crossbar. A bolt carrier for a firearm having a pair of vent holes disposed in the indented portion and at least one additional vent hole on indented portion adjacent to the pair of vent holes. A bolt catch for a firearm having a receiving portion curved to match the contours of a human thumb. A scope assembly for a firearm having markers on a scope and amount that correspond to the same radial positions. A bolt for a firearm having a plurality of ribs disposed on a main body and extending from a front end toward a tail portion of the bolt.

Safety lock mechanisms (C1-C28) for a portable weapon is disclosed. Such a mechanism includes an actuator (M3), and locking means operable from an unlocked state to a locked state by the actuator (M3) for blocking a firing sequence of said portable weapon. The blocking of the firing sequence is carried out at a trigger, a trigger lever, a hammer, or a firing pin of the portable weapon. The actuator (M3) may be a push-pull solenoid or servo motor.

A charging handle, charging handle latch, and firearm with a charging handle. The charging handle includes a charging handle body that extends between a front and a rear of the charging handle; a crossbar at the rear of the charging handle, wherein the charging handle body has a top surface and a bottom surface opposite the top surface, wherein at least a portion of the bottom surface bottom surface defines a first plane. The charging handle further includes a latch pivotally connected to the charging handle, wherein the latch includes a gripping surface configured to be depressed by a user, wherein an extension portion of the latch extends below the first plane.

A breech block assembly for a firearm includes a guiding element having a slide adapted to slide along a guide in an actuation system of the breechblock assembly driven by a motor. A shutting element shuts an opening in a breech ring of the firearm. A percussion pin is pushed by an elastic element slide along a longitudinal axis, as a function of the firing cycle of the firearm to an axial hole in the shutting element. The percussion pin is shaped to partially come out of the axial hole of the shutting element for firing a piece of ammunition. The breechblock assembly comprises a control system for controlling the percussion pin. The control system controls the operability and the movement of the percussion pin independently of a firing cycle of the firearm.
