Very hideous looking to be sure. . .and as JasonC8301 alluded to regarding LUMENS! Somehow the marriage of an LED head with the SureFire M6 doesn't mix.
Thank you all, I was just looking to put the KL6 on the m6 to use indoors. That way I could have a bright LED with a looooooong runtime. If you have an M6 and a Kl6, beamshots would be greatly appreciated.
