A stock for a movable firing unit equipped with an intermediate magazine with an internal lever cartridge feeder comprises a metal component based on a profiled carrier lengthy element and polymer components. Polymer components are made in the form of an upper longitudinal cover of a weapon that carries parallel recoil buffer of the firing unit and a return mechanism of a bolt support with a reloading handle, which is fixed in process of firing, under a longitudinal safety bracket. A protective neck for the lower longitudinal window and its lower cross links are connected with lower ends of weapon handles having polymer pads. ^ EFFECT: optimal ratio of strength and weight indices. ^ 6 cl, 3 dwg |
