The SAI 6 1-6x24mm Riflescope was built with ruggedness and versatility at the core of its design. The reticle has a free-floating center cross with hash marks directly below to compensate for elevation as well as windage compensation holdover dots in the “Christmas tree” setup. The SAI 6 also has a VSOR rangefinder in the lower left-hand corner of the reticle, this feature allows the shooter to accurately estimate the range of objects with a known height. In addition, the reticle is in the first focal plane so the reticle shrinks and grows as you zoom in or out with your target for greater flexibility at any range.
