Okay, here's the Henry .410 info with regard to choke tubes:
The tubes I ordered from Henry on 2-27 came yesterday; a Skeet and a Turkey tube with a knurled ring. They're made by Briley, just like the nice lady said. The internal portion is 2" overall, but they're 1 3/4 from the front to the beginning of the threads, so Carlson's Invector tubes won't fit, which is fine.
