Can't confirm authenticity, I've never seen suppression like this... but I want to believe it's real. https://video.nostr.build/c6f0df0597f45c8702a712a6727a5fa138427dce357690e2e27b0b5feaff4e84.mp4

There is no magic in a suppressor. The action running is exactly as loud as if you pull it back and let it go to chamber a round.
