With over seventy-five years in the business, Weaver Optics is an American company dedicated to assisting the hunter's pursuits at a great price.  The 6-20x40 A/O Grand Slam® is equipped with Weaver's best stuff, featuring all you'll need in a premium scope at a price that isn't too expensive.

The 6-20x40 A/O Grand Slam® features Weaver's Micro Trac® 4-point elevation/windage adjustment system, which allows you to adjust one without affecting the other.  Conventional adjustment systems employ two adjusting screws and a single biasing spring, which eventually results in the spring affecting the adjustment of the other axis after you've tried to adjust one screw too far.  Rather than bearing down directly upon the erector tube itself, the Micro-Trac® 4 Point System bears down upon a single, consistent point of contact-for repeatable, unparalleled accuracy.
