The Leupold Mark 6 was designed to serve the most common need for optics in tactical situations, that is to be light, fast, and small. The Leupold MK 6 delivers on all three of those requirements, and it will earn favor with even the most stringent critics. Culminating in the Leupold Mark 6 3-18x44mm, every Mark 6 ships free and is a great value for the performance it delivers. Don't forget, Leupold rifle scopes come with a Golden Ring Lifetime Guarantee, so if the scope doesn't perform like it is supposed to, they will either fix it or replace it to make things right.
