This SureFire is made up of leftover parts. It's a KL4 LED head from an old SureFire Scout M600, with the crenellated bezel from an E2D, and a tailcap from an old E1B Backup. All those parts are black anodized. The body is from an E2L Outdoorsman and is type 3 gray hard anodized. Single stage, runs on 2x CR123A batteries, not included.
