Anyone have any ideas?
What in the world is this for?
I don't think that is a standard thread anywhere in the world, so there aren't going to be any taps for it.

It's a standard .45ACP suppressor thread.
I would hope that suppressor manufacturers are single-point CNC turning threads for concentricity's sake.
Any reason not to install a can instead of a flash suppressor?
