Partially closed muzzle brake for use on large-caliber long gun pipe, has chambers connected with bores by screwing disks with different bore diameters, where bore diameters run conically forward, and one of chambers has perforated grid

摘要

The brake has bouncing surface disks (2) screwable with inner-lying chambers and provided with circulating pressure relief bores (4), where diameters of the bores run conically forward. One of the chambers arranged at an end of the brake turned towards a partially closed muzzle has an oval perforated grid. The chambers are equally large, and bore diameters exhibit values of 11 mm, 10 mm, 9 mm, 8.5 mm and 8.2 mm. The chambers are connected with the pressure relief bores by screwing the bouncing surface disks with different bore diameters.
