The Salvo 12 is the only commercially-viable, modular, hearing safe shotgun silencer on the market. Designed to operate with most pump 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. Configurations of 6″, 8″, 10″, and 12″ allow the end user to customize the Salvo 12 for sporting clay, waterfowl, turkey hunting, home defense, and many other applications and accept the appropriate trade off of size for sound reduction.
