A suppressor, also referred to as a silencer, is a tool connected to the barrel of a firearm to cut 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 capturing, searching, and army functions. In goal capturing, suppressors may help to cut back noise air pollution and make it simpler to focus on the goal. In searching, suppressors may help to cut back the noise of the gunshot, which may be helpful for stealth searching. In army functions, suppressors may help to cut back the noise of gunfire, which may be helpful for covert operations.
