A computer-implemented method of a smart-gun system that includes obtaining a set of smart-gun data, determining one or more states of a smart-gun based at least in part on the set of smart-gun data, determining one or more states of a user based at least in part on the set of smart-gun data, determining to generate a conversation statement based at least in part on the one or more states of the smart-gun and the one or more states of the user, and presenting a conversation statement generated based at least in part on the one or more states of the smart-gun and the one or more states of the user.

US12467705 - Ambidextrous bolt catch system

An ambidextrous bolt catch system for a firearm receiver includes a neck having upper, middle, and lower portions; a bolt catch at the upper portion; and an ambidextrous actuator at the lower portion having a spring retention structure. The middle portion extends along a plane perpendicular to a vector extending from the rear to the front of the receiver, and includes a first terminal point towards one side of the receiver, the upper portion extends along the plane and includes a second terminal point towards the side and further than the first terminal point, and the lower portion extends along the plane and includes a third terminal point towards the side and beyond the first terminal point.

US12467706 - Trigger mechanism for firearms

The invention is aimed at improving the accuracy of shooting by reducing the force on a trigger of a firearm during firing. The technical result is achieved by the fact that the design of the trigger mechanism includes a housing in which a hammer and a hammer spring are installed, a tubular axle on which the trigger having a groove allowing longitudinal movement along the axle is installed, thereby disengaging a return mechanism installed in its housing, a roller sear, and a single-fire sear. To engage the return mechanism, the trigger and the hammer are equipped with cams, and when a breechblock carrier is recoiled, the hammer is lowered and its cam affects the trigger cam, forcing the trigger to move backwards (if it has been moved to a forward position before). The return mechanism is also engaged when a safety lock is activated.
