Description

Technical Field

[0001] The utility model relates to the technical field of gun muzzle suppressors, in particular to a tool for assembling and disassembling a gun muzzle suppressor. Background Art

[0002] Muzzle noise has always been a problem that has troubled scientific researchers, especially the muzzle noise generated by supersonic bullet firing. In recent years, newly developed firearms that fire supersonic bullets are required to be designed with muzzle suppressors to reduce firing traces. For example, domestic 5.8mm rifles and 7.62mm sniper rifles are all equipped with muzzle suppressors. First, the muzzle suppressor has high noise reduction requirements and needs to be designed with a longer suppressor barrel. Due to the limitations of structure, weight, and economic indicators, the suppressor barrel is usually designed as a long cylinder. When installing the suppressor barrel on the suppressor connector, due to the long barrel, general tools cannot be used to assemble and disassemble it; second, after the muzzle suppressor fires a bullet, a large amount of gunpowder residue is attached to the inner wall of the suppressor barrel, which is difficult to remove with a general brush, affecting the noise reduction effect.
