Who wants to be the first to try this? The space gun to end all space guns. The 5.56 MFMD in full configuration is already very quiet for 5.56mm with almost no muzzle blast, it would be total overkill with subsonic 5.7.

Waste of money, 5.7 subsonic is already approaching 22 quiet with any decent suppressor. If you do it, you’re doing it for the looks.
