The first couple inches just past the shoulder would be threaded 1 1/4 x 18, and any 1.25" section ahead of the threads turned down to just below the minor diameter. The shoulder feature could be performed with a lock nut or spacer.

Rather than cutting AR receiver threads on the barrel itself and threading an AR barrel nut on there, I was just thinking of making a replacement barrel nut that the desired handguard attaches to and then boring the inside out so that the barrel clamps it against the receiver like a recoil lug.
