The basic answer to your question is yes. TC barrels as well as Bullberry barrels use the same spacing for their dovetail nuts mounted in the barrel. So you can take a hanger bar setup from a Bullberry or VVCG barrel and put it right on your TC barrel and put their wood on it. The hanger bar is an 'add on' as opposed to something exclusive and different. Go for it.....makes a great setup and if you ever decide to go full custom you will be already setup.
