Subsonic 308 Ammo: How Quiet is it?

This video demonstrates the effectiveness of the Zuk suppressor, which utilizes metal foam technology for sound suppression. The test involves firing standard and subsonic 7.62x39 rounds from an M72 Zastava rifle (an RPK variant) to showcase the significant decibel reduction achieved, particularly with subsonic ammunition.

This video highlights the effectiveness of subsonic 7.62x39mm ammunition when paired with a ZVUK suppressor. The speaker demonstrates how this combination significantly reduces firearm noise, to the point where it can be fired without disturbing neighbors. The key to the quiet operation is the ammunition's inability to cycle the bolt, which is a major source of noise in standard 7.62x39mm.

This video explores the Zebook suppressor, featuring a porous metal foam design for sound suppression. Tested on a Zastava M70 RPK chambered in 7.62x39mm, the suppressor demonstrated significant noise reduction, particularly with subsonic ammunition. The metal foam's porous structure is highlighted as key to slowing gas escape and reducing decibel levels.

This video demonstrates the significant impact of a suppressor on a Rossi 45-70 lever-action rifle. The presenter highlights how the suppressor effectively tames recoil and reduces noise, making the shooting experience more manageable, especially when comparing subsonic and supersonic ammunition.
