Description

Technical Field

[0001] The utility model relates to a muzzle brake and belongs to the technical field of weapon equipment. Background Art

[0002] The muzzle brake is a hollow tubular structure with multiple through holes on the outer shell. The muzzle brake is installed at the muzzle. On the one hand, it reduces the forward flow of gunpowder gas through the central bullet hole, thereby reducing the recoil force on the weapon; on the other hand, it flows out from the side channel, changes the direction and size of the airflow, and sprays to the side and rear, thereby giving the weapon a forward reaction force. Installing a muzzle brake can improve the shooting stability of the weapon and reduce the weight of the weapon because it reduces the recoil impulse during firing. In the prior art, the muzzle brake is often installed on the barrel by welding or riveting, and cannot be disassembled, which makes it inconvenient to inspect and maintain the muzzle brake.
