No, never was interested in the Invictus. I just do not like the "plunger" form factor.
I wonder if SF will ever incorporate the Invictus head on a M6 body ?
I see the M6 has a problem when it comes to playing host to "advanced" features such as LED bezels and "two-stage" TailCaps:
The M6's problem is it's incandescent legacy.
The body has volume/length forward of the battery compartment to accommodate the incandescent Lamp Assembly and it's shock isolation system.
A new body designed specifically for LED bezels would be shorter; obviously shorter. And it would allow the LED bezel to be obviously shorter too.
The TailCap could be a 4FTC but there are signal path issues with the MB20 I think. And as the M6LT is now it would make it even longer (I've seen a Clickie TailCap prototype for the M6 and it was too long).
Best we can hope for our M6 flashlights is a single-output LED bezel to replace the incandescent bezel. Not that we should trust such things but the vibe is that the KX9T bezel is coming once the M6LT orders are filled.
I'd much prefer SureFire concentrate on releasing the UDR though.
