With some trepidation, I took it out of the 4-jaw setup and tried it in the body,
where the fit did, indeed, prove to be just perfect. Now we needed some holes:
The other half of the mod was to make the retainer screw hole not only deeper,
but also not pressurized. The screw now fits into a blind hole, with almost
four times more thread than the original design.

Now, how did we get air through, since we can't drill down the center anymore?
Easy: I marked out what space I had to play with- that's the red dykem on the end.
I had two spaces to the sides of the screw hole, and inboard of the O-ring grooves.
So I just passed two .110" holes through to the ASA chamber. They're smaller than the
huge port the factory part had, but still more than enough to keep the gun fed.
