PBS-1 Suppressor

The PBS-1 Suppressor is a silencer that was designed for use with the AK-47 Soviet rifle. It is 40mm in diameter and 120mm in length.

History
The purpose of a firearm suppressor is to reduce the noise generated by the ammunition when firing.

Although such devices are frequently referred to as "silencers," they cannot in fact silence a firearm discharge entirely, but rather they reduce the overall decibel (dB) level of the discharge.

The PBS-1 suppressor, designed for use with the AK-47, is a two-chambered suppressor utilizing baffles and a rubber wipe. It was designed for use in conjunction with subsonic rifle ammunition and has been extensively tested by the United States Army Foreign Weapons Test Lab.

Used mostly by Spetsnaz forces and the KGB, the rubber wipe in the PBS-1 requires replacement after 15 rounds [citation needed]. With a rubber wipe in place the PBS-1 reliably reduces the sound of an AK-47 discharge by 15 dB.
