Everyone who owns a gun owns a shotgun, but until SilencerCo stepped in, most of them had never been suppressed. The Salvo 12 is the only commercially-viable, modular, hearing safe shotgun silencer on the market. Designed to operate with most pump action and semi automatic shotguns and almost all commercially available ammunition, at its full length of 12″ the Salvo 12 brings sound down to 136.8 dB at the muzzle with #7 shot.
