A suppressor, also called a silencer, is a tool hooked up 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, looking, and navy purposes. In goal capturing, suppressors can assist to cut back noise air pollution and make it simpler to focus on the goal. In looking, suppressors can assist to cut back the noise of the gunshot, which could be useful for stealth looking. In navy purposes, suppressors can assist to cut back the noise of gunfire, which could be useful for covert operations.
