SYSTEMS AND METHODS FOR HAND-HELD SMALL ARMS WITH FIRE SELECTIVE MECHANISM Russian patent published in 2021 - IPC F41A17/46 

FIELD: weaponry.

SUBSTANCE: hand-held small arms with a fire selective mechanism, having an automatic fire mode with an open bolt and semi-automatic fire mode with a locked bolt, contains a trigger mechanism with a trigger support, which ensures that when the trigger is released in the automatic fire mode with an open bolt, the bolt carrier stops in the open bolt position, held by the sear with an open bolt. The trigger support may include a support that, following the first pull on the trigger in automatic fire mode with an open bolt, slides under the rear end of the trigger and props it up in a position that allows the sear with an open bolt to capture the bolt carrier, when the trigger is released and propped up, but prevents the firing pin from engaging with the trigger sear.

EFFECT: eliminating a premature shot due to sending a cartridge into a heated barrel after automatic fire.
