Over the course of its production history, the M6 has gone by a variety of names including MagnumLight, Millennium Magnum, and finally Guardian.  Due to its larger body size, the M6 uses a unique tailcap that is not interchangeable with any other handheld SureFire lights.  The bezel threads match those found on the M3 and M4 Devastator.
