Anyone who takes a very nice original '03-A3 and replaces the barrel for whatever reason is a Bubba, but not necessarily the professional gunsmith who was paid to do the work.
Just my 2c worth. And the number$ will support it! And the number$ don't lie.

p.s.,
If the rifle has been arsenal overhauled, refinished, and re-assembled from mixed parts, then re-barreling can be justified if necessary.
