Straight-pull breechblock (20) with rotating-boss locking mechanism for repeating weapons, having a breechblock head (27) which is guided in a longitudinally and rotationally movable manner in a breechblock housing (22) and has locking bosses (42, 43), and having a breechblock sleeve (24) which carries a bolt handle (28) and in which is mounted a firing pin (23) which is acted upon by a firing spring (53), for the movement of the breechblock head (27) in the longitudinal direction, while the rotational movement thereof is forced by way of the pretension of the firing spring (53) which acts on the firing pin (23), wherein by way of a forcibly controlled spring-mounted stopping lever (58) associated with the breechblock sleeve (24), relative movements between the breechblock head (27) and the breechblock sleeve (24) can be prevented until the breechblock head (27) has gone into the region of the locking chamber (44) of the breechblock housing (22).
