The Diligent Defense Co Zilch HUB Adapter is a titanium thread adapter that lets a Cherry Bomb style muzzle device mount to a suppressor with industry-standard 1-3/8×24 hub threads. Those threads are also called ASR or Bravo, and Diligent Defense says they fit all of its own suppressors plus many others that share the thread. The adapter is machined from 6-4 titanium and weighs only 1.5 ounces, so it adds very little to the front of the suppressor. It lengthens the setup by just 3/16 inch (.187 inch), which keeps the whole package compact. A hex on the outside of the adapter makes installation and removal easy with a wrench.
