The invention relates to the breech of a fire arm with a breech head (11), a breech carrier (13) and a resilient annular catch (27). Said annular catch having a longitudinal slot is disclosed in German Patent DE 197 13 988 C1 and is allocated to a device that prevents the annular catch from freely oscillating in order to allow a complctcly troublefree operation. According to the invention, a widened bore section (25) is preferably configured in the breech carrier (13) which bore section accommodates the rear end of the annular catch (27) in the unlocked position, thereby preventing the annular catch from excessively oscillating.
L'invention concerne une culasse d'arme à feu, du type comportant une tête de culasse (11), un support de culasse (13) et une bague d'arrêt à ressort (27), dans laquelle la bague d'arrêt à rainure longitudinale, connue par le brevet allemand DE 197 13 988 C1 est associée à un dispositif l'empêchant d'osciller librement, en vue de garantir un fonctionnement complètement exempt de perturbations. De préférence, il est prévu, dans le support de culasse (13), une section d'alésage agrandie (25) qui, lorsque la culasse est déverrouillée, reçoit l'extrémité arrière de la bague d'arrêt (27). On empêche ainsi que celle-ci oscille indûment de tous côtés.
