Now the LU60A is the E to C adaptor that comes with the scout light; see below how the only way to attach that huge M head would be with the use of the LU60A adaptor.
The photo shows an M600B ScoutLight (with it's E2e bezel and Z68 shrouded Clickie TailCap, MH60 Housing Body and M75 thumbscrew rail mount), a KL4-BK LED bezel, a UE07 (UE00 TailCap with ST07 remote pressure switch on a 7" long plug-in cable).
The M600A features the KL4 bezel
The M600B features the E2e bezel
The M600C features the KX2C bezel
The M600C KIT01 additionally features the LU60A Lamp Module and FM63 IR BeamFilter.
The photo shows the M952C WeaponLight consisting of the MH90 Millennium Universal Housing Body, SW02 shrouded Clickie TailCap, LU60 Lamp Module and M50 ARMS Throw Lever Mount
It's important to specify which bezel you mean by "M head" as there are essentially three:
"M2" bezel
"M3" bezel (Z46)
"Millennium TurboHead bezel"
If you purchase the two WeaponLights in the photos show above you will not get the LU60A since it is not shown, nor the KL4-BK even though it is. You will not be able to attach the "M2" bezel from the M95 to the ScoutLight housing body. To achieve this you much have either the adapter collar from the LU60A (which is not sold individually AFAIK), or perhaps an aftermarket so-called "E to C" adapter.
I hope this helps?
