Did this ever end up manufacturing teenut's ideas?

I do not think so. If I recall correctly the outfit isn't in business any longer, either. Could be wrong though.

Teenut passed away.

The company was sold to his brother in law who did nothing with it.

I understand from an AR forumite's post that the facility was empty as of a couple of years ago.

500, I remember he passed away. I did a net search the other day on big bores and a page came up with one of his posts on it from some metal working forum in about 2000! It was a bit poignant.
That's why I asked about the company.
