Breechblock assembly for a firearm and related firearm

A firearm comprising:

• a recoiling mass;
• comprising:
• a breech ring;
• a barrel;
• a braking system adapted to brake recoiling motion of a recoiling mass of the firearm;
• an actuator system for actuating the firearm, moving integrally with said recoiling mass;
• a breechblock assembly, comprising:
• a guiding element comprising, a slide adapted to slide along a guide comprised in an actuation system of the breechblock assembly driven by a motor;
• a shutting element, adapted to shut an opening in the breech ring of the firearm;
• a percussion pin, which is pushed by an elastic element;
• said shutting element comprising an axial hole in which said percussion pin is adapted to slide along a longitudinal axis, as a function of a firing cycle of the firearm with which said breechblock assembly is associated;
• said percussion pin being shaped to partially come out of said axial hole of the shutting element for firing a piece of ammunition;
• said breechblock assembly comprising a control system for controlling the percussion pin;
• said control system being adapted to control prevention of movement of the percussion pin independently of the firing cycle of the firearm;
• the breechblock assembly adapted to connect to the breech ring to allow firing the piece of ammunition;
• an actuation system for said breechblock assembly, adapted to move said breechblock assembly into different positions, as a function of firing phases of the firearm.

A breechblock assembly for a firearm, comprising:

• a guiding element comprising, a slide adapted to slide along a guide comprised in an actuation system of the breechblock assembly driven by a motor;
• a shutting element, adapted to shut an opening in a breech ring of the firearm;
• a percussion pin, which is pushed by an elastic element;
• said shutting element comprising an axial hole in which said percussion pin is adapted to slide along a longitudinal axis, as a function of a firing cycle of the firearm with which said breechblock assembly is associated;
• said percussion pin being shaped to partially come out of said axial hole of the shutting element for firing a piece of ammunition;
• said breechblock assembly comprising a control system for controlling the percussion pin;
• said control system being adapted to control prevention of movement of the percussion pin independently of the firing cycle of the firearm;
• wherein:
• said guiding element comprises a housing;
• said breechblock assembly comprising a supporting element adapted to be partially inserted into said housing of the guiding element, positioning said supporting element coaxial to said housing;
• said supporting element being pushed by a second elastic element;
• said percussion pin being adapted to be housed, at least partially, inside said supporting element;
• said axial hole being shaped for receiving, at least partially, said supporting element;
• said guiding element, said supporting element and said shutting element being constrained to one another so that said shutting element and said supporting element are telescopically movable relative to said guiding element.
