The housing has a bullet passage, a through slot for exit of powder gases, a nut-screwing thread, a dial, threaded holes for fixation of the housing, a radial projection for fixation of the housing on the insert and prevention of displacement of the housing along the gun barrel axis, a slot to provide crimping of the insert with the housing. The housing channel has diameter that is larger than bullet diameter. The insert has a thread for fixation on the barrel, radial slots for attachment of the housing, a slot to provide fixation on the barrel of the insert at its being crimped with the housing. The muzzle brake has a hole for installation on the housing, a groove for fixation on the housing, arrangement of the spring and provision of movability along the housing, a diaphragm for reflection of powder gases, openings formed with adjacent diaphragms, and an index.EFFECT: improving accuracy of hits of small arms, reducing jumps during shooting and providing unification of the device for different examples of small arms.2 dwg |
