5.56 vs 300 BlackOut || Suppression Sound Test

This video demonstrates techniques for using subsonic 7.62x39mm ammunition with a suppressed AK-pattern rifle, particularly in a hypothetical zombie apocalypse scenario. It highlights the need for adjustable gas systems or manual cycling due to insufficient energy for automatic ejection with subsonic rounds. The instructor also emphasizes conserving valuable ammunition and explores a method to further quiet shots by manually holding the bolt forward.

This guide demonstrates how to significantly reduce the noise signature of an AK-pattern rifle by attaching a specialized suppressor and employing subsonic ammunition with manual bolt cycling. The Zastava Zhuk titanium suppressor is featured, enabling a 'bolt gun quiet' experience when combined with ammunition that doesn't cycle the action. This technique allows for extremely quiet shooting, emphasizing the difference between the gunshot sound and the impact on a target.
