The Bowers Group Wardog K9 is the shortest hearing safe wipeless dry 9mm/300 Blackout silencer in the world.
At 1.7 X 4.3 inches long, it weighs in at a featherweight 7.8 ounces but is still rated for heavy full auto fire with both 9mm and 300 Blackout, both subsonic and supersonic.
You can expect it to be hearing safe on 16″ .300 Blackout rifles that are set up correctly. In shorter barrel lengths firing .300 Blackout, it will not be hearing safe, but will be significantly better for fighting with than no silencer, and will work well enough that it will keep you from being stunned by your own gunshots in a small room even with a very short barrel. You’ll want to use hearing protection when training with shorter barrels.
