The D-EVO's unique design lets you move between your 1x red dot site and the 6x magnification D-EVO by simply shifting your eye line–not your head. Now you can quickly move between close-quarter shots and mid-range shots with speed and accuracy. Whether your target materializes at 20 yards or 200 yards, you'll be ready to engage. It's not magic, it's the future of carbine optics. Discontinued and hard to find, like new.
