I have a question about the Blackout that indexes back over the barrel. It's my understanding that there are 2 different socket sizes you can get (large socket: fits .755 barrels & small socket: fits .670 barrels).

Does this mean that the portion that fits over the barrel needs to almost be an interference fit, or does an air gap not matter? I'm confused as to whether the design is to ensure concentricity with the bore, or to reduce OAL with the suppressor, or both.

Any insights are appreciated.
