MUZZLE BRAKE Russian patent published in 2022 - IPC F41F1/08 

FIELD: weapons.

SUBSTANCE: muzzle brake comprises a body with an annular section, conical and cylindrical sections defined by walls, windows in the front part of the walls, a front wall of the body, bosses in the front part of the body with vertical windows in the bosses. The internal diameter of the annular section and the minimum internal diameter on the conical and cylindrical sections of the body are made equal to the bore caliber, the body is rotated around the longitudinal axis by 90 degrees with the walls positioned horizontally. The bosses, symmetrical relative to the central horizontal plane, are made T-shaped in a normal section. Windows are formed between the bosses, arranged symmetrically relative to the central vertical plane. The back wall of the bosses is made of two interconnected vertical faces, mirrored relative to the longitudinal vertical plane of the body. The angle of inclination of the back wall faces from the central vertical plane equals 70 degrees.

EFFECT: structural simplification and increased momentum of the tractive force of the structure.
