A suppressor sometimes called a “silencer,” is a device attached to or integrated into the barrel of a firearm that reduces the amount of noise and visible muzzle flash when the gun is fired.
Suppressors are most commonly used on pistols, rifles, and submachine guns. Some common pistol suppressors include the H&K USP Tactical, Glock 17/19 TSF, Smith & Wesson M&P9, and Sig Sauer P226. examples of rifle suppressors include combat application rifles like the Colt M4 and M16 series, PKM machine guns, sniper rifles like the PSG-1, and recently popular tactical carbines such as the Heckler & Koch XM8. There are also several submachine gun suppressors available, including the FN P90 and Heckler & Koch MP5.
How do suppressors work? Suppressors work by trapping the expanding gases that are released when a bullet is fired. These gases are what create the loud noise and bright flashes that are associated with gunfire. By trapping these gases, suppressors can reduce the noise of a gunshot by up to 20 decibels. This can be a significant reduction, especially if multiple shots are fired in quick succession. In addition, suppressors can also help to reduce muzzle rise and felt recoil, making them more comfortable and accurate for shooters.
