Update: I emailed Henry Arms on Saturday got a response today (Sunday). Anthony Imperato must put in a lot of overtime. Good news for owners of these rifles.
Thank you very much for owning a Henry. The H003 is a round barrel and the front sight is fixed blade. HiViz is coming out with a fiber optic in January that will fit that gun and our H001 levers as its same sight.
Sincerely,
Anthony Imperato
President
