Thanks for the suggestion, but....
the tool shown in the website that you were kind enough to supply is quite similar to that shown in the catalogs I looked through at a local tool and hardware retailer.
The headache we have with the disc which needs to be removed from the front of the suppressor in order to disassemble it is that it is recessed into the tube approximately 1.5 inches. At this point, I am sorely tempted to check with local machine shops and simply have one made for me. Unfortunately, that would mean having to bring it in, and, being security-conscious, I am not wild about that idea.
Anyhow, thanks for the followup!!
