Embodiment Construction
[0038] combine figure 1 , figure 2 , a double-layer rectification type 3D printed small-caliber muzzle brake of the present invention is an integrated centrosymmetric structure, with an inner cylinder 6 and an outer sleeve 1 .
[0039] Taking the direction pointed by the muzzle as the positive reference, the inner surface of the bottom end 9 of the inner layer cylinder is provided with a connecting thread, which is connected with the outer surface thread of the gun barrel head to form a thread pair.
[0040] Inner layer cylinder 6 head inner diameters are not less than the barrel caliber. The circumferential wall of the head of the inner cylinder 6 is provided with multiple groups of waist-shaped side holes 7 distributed symmetrically about the center of the gun axis. Each group of waist-shaped side holes 7 is equidistantly distributed along the gun axis direction with a plurality of waist-shaped side holes with different reclining angles and areas. In every group of waist...
