Mount the Leupold Dual-Enhanced View Optic (D-EVO) in front of virtually any compact red dot sight and instantly maximize the range of your AR style rifle. 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 deadly 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.
