摘要

The adjustable barrel muzzle attachment is used for bullet firing barrels of small firearms. This muzzle attachment ensures precision firing of bullets. Narrow slots following the rifling of the barrel are arranged in the adjustable muzzle attachment. These slots are used for stepless choke formation of the barrel. The barrel (3) outside surface (4) is conical and it has screw threads (5) on which is screwed a conical nut (7). Marks are drawn on the barrel for indicating a previously selected useful choke position of the barrel muzzle (9).
