Abstract: A bolt for a firearm having an extractor for cartridge cases, comprising a cylindrical body having a locking portion with a breech face, an undercut, groove-shaped, rearwardly-running recess for an extractor with an extractor claw and a leaf spring, as well as an inwardly-projecting bearing protrusion and a second lever arm with a rearwardly-projecting spring bearing portion. The bearing protrusion is designed to be hook-shaped so as to abut against the extractor axis in the installed state with a bearing opening open rearwardly, and, on the body, the groove-shaped recess for receiving the leaf spring is laterally open at least partially on one side tangentially to the circumferential direction, via an insertion portion, and is designed to merge laterally and/or rearwardly into the undercut, and the body has a cavity for receiving the bearing protrusion relative to an imaginary plane of the recess in the region of the extractor axis.

Abstract: The invention relates to a bolt (1) having an extractor (2) for cartridge cases (4), comprising a cylindrical body (11) having a locking portion (13) with a breech face (15), an undercut, groove-shaped, rearwardly running recess (12) for an extractor (2) with an extractor claw (22) and a leaf spring (3), as well as an inwardly projecting bearing protrusion (23) and a second lever arm with a rearwardly projecting spring bearing portion (24), wherein the bearing protrusion (23) is designed to be hook-shaped so as to abut against the extractor axis (21) in the installed state with a bearing opening (231) open rearwardly, and, on the body (11), the groove-shaped recess (12) for receiving the leaf spring (3) is laterally open at least partially on one side tangentially to the circumferential direction (92), via an insertion portion (122), and is designed to merge laterally and/or rearwardly into the undercut (121), and the body (11) has a cavity (16) for receiving the bearing protrusion (23) relative to an imagina
