The ZEISS LRP S3, with up to a staggering 160 MOA of total elevation travel, can deliver bullet impact on the most distant targets. Advanced optics allow the shooter to quickly locate and define the targets. The optical performance is assured via the use of multiple elements of ED glass, ZEISS T* (T-Star) lens coating, and 90% light transmission. The ZEISS Ballistic Stop, with its robust design and all-metal construction, provides an absolute and repeatable zero under any condition. The external locking windage turret offers the shooter easy access for immediate wind corrections and a locking feature to hold the setting. The daylight visible illuminated reticle - with a user-selectable option of red or green illumination - assures a viable point-of-aim in any lighting condition. Other features include side parallax with 15 meters to infinity adjustment range and one of the most rigorously shock tested first focal plane riflescopes available, tested up to 1,500 g-force.
