I'm using the rotary indexing head now. Cutting the front sight base, cutting the rear sight base major diameter. Very tedious work. 4º cut at a time. (One rev of the indexing crank).
I'm not happy having to set the indexing head & chuck on one end of the barrel and do my cutting at the other end. But there's no room behind the work table, and the indexing head only has right-hand crank.
