Abstract

FIELD: weapon, in particular, machine guns suing an optical or night sight. SUBSTANCE: to reduce the barrel thermal warpages and increase the quantity of similarly adjusted barrels in the weapon, a casing-screen is press-fitted on the barrel section past the gas chamber, and the muzzle is connected to the casing by means of a bush. The bending strength moment of the casing exceeds the bending strength moment of the barrel, and the bush is made with an eccentricity relative to the barrel. EFFECT: enhanced injurious effect.

Изобретение относится к оборонной технике, в частности к пулеметам, содержащим оптический или ночной прицел. С целью повышения эффективности оружия в процессе стрельбы путем снижения величины термических поводок ствола и увеличения количества одинаково пристрелянных стволов, в оружии на участке ствола за газовой камерой напрессовывается кожух-экран, а дульная часть ствола соединена с кожухом с помощью втулки. При этом момент сопротивления кожуха на изгиб больше момента сопротивления ствола, а втулка выполнена с эксцентриситетом относительно ствола.The invention relates to defense equipment, in particular to machine guns containing an optical or night sight. In order to increase the effectiveness of the weapon during the shooting process by reducing the thermal lead of the barrel and increasing the number of equally shot barrels, a shield casing is pressed in the weapon in the section of the barrel behind the gas chamber, and the muzzle of the barrel is connected to the casing with a sleeve. The moment of resistance of the casing to bending is greater than the moment of resistance of the barrel, and the sleeve is made with an eccentricity relative to the barrel.
