Leupold released this video of their D-EVO or Dual-Enhanced View Optic last 6 February 2015 on YouTube... "Revolutionary solutions require original thinking. Leupold engineers have innovated again with the new D-EVO, an optic that creates a new class of carbine optics. A unique, innovative design allows the 6x20mm D-EVO to be fused with virtually any red dot sight to deliver the previously unobtainable --- a magnified image for long-range precision, a bold aiming point for reflexive shots, and the ability to switch effortlessly between them with the mere movement of your eye."
