Firing pin release system

A firing pin release system, comprising:

• a support;
• a first sequence of a plurality of bores distributed about an axis at a first distance from said axis;
• a second sequence of a plurality of bores distributed around said axis at a second distance from said axis which is different from said first distance;
• a plurality of firing pins each disposed in a respective bore and movable at least parallel to said axis, each firing pin comprising a first extremity adapted to strike a primer of a cartridge and a second extremity arranged to be retained in a cocked position by a retaining system rotatably mounted on said support about said axis;
• and
• a plurality of firing pin springs each arranged to bias a respective firing pin towards a fired position,
• the retaining system adapted to retain said firing pins in a cocked position against an effect of said firing pin springs,
• said retaining system including a rotatable ring carrying a first shoulder extending along a circle centered on said axis and adapted to cooperate with the second extremity of each firing pin situated in said first sequence of bores, so as to retain each firing pin in the cocked position against the effect of the corresponding firing pin spring, said first shoulder comprising at least one opening adapted to permit the passage of the second extremity of said firing pins, and
• said retaining system also including a second shoulder extending along a circle centered on said axis and adapted to cooperate with the second extremity of each firing pin situated in said second sequence of bores so as to retain said firing pins in the cocked position against the effect of each corresponding firing pin spring, said second shoulder comprising at least one further opening adapted to permit the passage of the second extremity of said firing pins.
