I bought the Leupold VX-I 1-4x20mm Shotgun Scope because of the Dark Earth® anodized finish and the quality of Leupold scopes. It is for my AR-15/M4. It works perfect for 50-75 yard firing. It lowers down to a 1.5x view so you can use it for close range sights. Vision is clear, dials are smooth, and finish is good looking. I mounted it to Burris AR mount and is a perfect match. Mount is solid and looks a little bulky compared to the small scope but that is ok. Operations matters more to me. Scope looks good with my dark earth tan accessories. Not a perfect match but good enough considering Magpul, Tangodown, Vltor tans are not a perfect match either.
