The duo has m4, but I believe the Vier is an M3. I have it on a different mount and had to re-tap it to an M4 (Although the Vier is probably a bit big for a helmet anyway, the Duo is fine, and I have the battery in my camelbak)
Strange that the Vier being larger has a smaller screw, my 5 LED main lamp is a design that looks near identical the Vier and has the same size screw as the rest. It is what it is I guess, I did wonder why the Vier wasn't offered with the excellent clamp/bracket that comes with the selecta, this explains that.
