The new KL4 Style LED Head Unit is now available.

The Surefire KL4 was truly a classic and iconic design, we are happy to be able to bring it back for the fans.
Available in HA3 Natural and HA3 Black anodizing with Flat or Crenelated Bezel options.

These heads will look great on any E series flashlights or M300/M600 Scout lights.
