Sur les armes semi-automatiques ou automatiques, mécanisme qui, actionné par le plateau du chargeur, retient la culasse vers l'arrière après le tir de la dernière cartouche; lorsqu'il s'enclenche, il faut recharger l'arme. Quand on insère un nouveau chargeur, le mécanisme se libère automatiquement ou on le libère manuellement. Alors, la culasse revient vers l'avant et introduit une cartouche dans la chambre. Sur les pistolets automatiques, il est appelé «arrêtoir de glissière». 2, record 2, French, - arr%C3%AAtoir%20de%20culasse
