I have one, new-in-box, Surefire X300 that I used during the setup of the light rail adapters. Exactly as new, batteries never installed. Includes one complete 1911 Light Rail kit (installed). Please choose one of the following finishes for your rail; Blued steel, Matte black anodized aluminum, or Satin anodized aluminum. Set includes one rail, two Delrin adapters, 3 mounting screws and installation instructions. Professional installation is highly recommended. The price includes Priority Mail shipping to US addresses only.
