Awhile back I saw pictures of a letter of approval that a guy had gotten for his contraption which was used for silencing paintball guns. I think I saw it on the X7OG, either originally or as a repost from somewhere else, but can't fully remember. This may be the pipe insulation thing, too. Like you, Doc, I'd be much happier to see a hard copy letter of approval for JCurt's baffled barrel tip, and then get a "Certificate of Authenticity" (as the infomercials say) with each purchase, being a xerox copy of that approval letter. On that issue we are in total agreement!
Even if it takes a few weeks or a few months, keep us updated on the progress of that part, JCurt. Then maybe we can all put this over-analysis to rest, ha!
