The reflector is held in place between the bezel ring and the body of the head
By screwing the head in or out, this will move the reflector backwards or
forwards, therefore allowing you to focus the beam.
Further focussing can be achieved by how deep or shallow you install the
dropin in the Mag.
Fred, trust me, you will not have any problems focussing the Malkoff for
more throw
I have two Malkoff Mags set up for throw, BTW use a smooth reflector
for maximum throw :devil:
I think maybe you are confusing the "unscrewing the head until it is about to fall off"
issue with Mags with aspheric lens installed
