A bolt locking housing (16) on a gun, behind the chamber (4) thereof, for receiving a bolt (6) including an extractor (10) having an extractor hook that grips a corresponding extractor groove (21) of a cartridge (2) within said chamber (4), characterized by said bolt locking housing (16) being asymmetrically machined internally, such that there is provided at least a first protrusion (18) that becomes co-aligned with and serves to support head of extractor (10), when bolt (6) is fully closed and lugs (7) thereon are interlocked into bolt locking housing (16), thereby preventing deformation of casing of said cartridge (2) after detonation.
La présente invention concerne un corps (16) de verrouillage du canon situé sur une arme, derrière la chambre (4) de ce dernier, qui est destiné à recevoir un verrou (5) comprenant un élément extracteur (10) pourvu d'une griffe qui retient une rainure correspondante (21) d'une cartouche (2) dans ladite chambre (4). Cette invention se caractérise en ce que le corps (16) de verrouillage du canon est usiné de manière asymétrique à l'intérieur, de sorte qu'il existe au moins une première partie saillante (18) qui s'aligne sur la tête de l'extracteur (10) à laquelle elle sert de support, lorsque le verrou (6) est entièrement fermé et que des pattes (7) formées sur cette dernière se bloquent dans le corps (16) de verrouillage du canon, ce qui empêche ainsi la déformation de la douille de la cartouche (2) après la détonation.
