A suppressor, also referred to as a silencer, is a tool connected to the barrel of a firearm to scale back the noise produced by firing. Suppressors work by trapping and increasing the propellant gases, which reduces the strain and velocity of the increasing gases, leading to much less noise.
Suppressors are sometimes used for goal taking pictures, searching, and navy functions. In goal taking pictures, suppressors may help to scale back noise air pollution and make it simpler to focus on the goal. In searching, suppressors may help to scale back the noise of the gunshot, which will be useful for stealth searching. In navy functions, suppressors may help to scale back the noise of gunfire, which will be useful for covert operations.
