Anybody have time on the newer generation SureFire vampire scout lights or X300Vs?

I think the latest is a KM1-C head for the 300-series mini-scout (which I have), the KM2-B for the 600-series, and the X300V-B.

Wondering how much they've improved the IR throw on the other models.

My KM1-C can just barely touch the 200-meter range at my local club under IR. But that's definitely improved over the older version, which you can read about here: https://www.m4carbine.net/showthread...e-light-output
