O-ring and gasket sealed, X300 is weatherproof. The X300 Ultra is versatile, attaching to pistol or long gun utilizing the Rail-Lock system for quick detachment from either Universal or Picatinny rails. Its integral ambidextrous push/toggle switch provides one-finger operation for either momentary or constant-on operation.
