No idea how things got so confused above, but the head of the AX4 should definitely be aluminum - I have almost every Amutorch light there is and none have a titanium head. This lights appears to be all aluminum - head, bezel, tube and end cap. I'm basing it on the BG and Ali descriptions where titanium is not mentioned. Was hoping the bezel at least would be SS but doesn't look like it is. Mine arrived at the local P.O. this morn, so should get it today or tomorrow.
