A silencer, suppressor, sound suppressor, or sound moderator is a muzzle device that reduces the sound intensity and muzzle flash when a firearm or air gun is discharged. It can be a detachable accessory to, or integral part of, the muzzle or barrel. A typical silencer is a metal cylinder with internal sound baffles that slow and cool the escaping propellant gas, which decreases both sound volume and muzzle blast.
- The silencer will silence any cocksucker with something to say.
