They're the hexless signature series for Mr.Dot (formerly known as KT)
I don't know about you guys but I want to see the beam shots from these gems!!! What can a properly designed parabolic reflector do with a 5W? I hope the KL4 and KL6 make it from print to part!!
Why? The Bezels stick out of your pockets anyway since the PocketClip is below the bezel.
The KL4 appear to be the same size as the M2 Bezel. The length and bulk of the KL4 would mean a different carrying experience compared to the E2e, but the KL1's length already changes the balance of the E2e (and especially the E1e). I'm sure that to have a KL4 on your E2e you'd manage to carry it!
If SureFire could make it smaller it would be smaller don't you think?
