The SP-5006’s overall design has been optimized for durability, ease of use and customization. The rings are diagonally cut for better visibility of the windage and elevation turrets, and the interior contact surfaces feature grooved texturing which can be used with adhesive to better secure the scope in place. This option is perfect for firearms prone to sever vibrations such as bench-rest shooters or for those used in off-road vehicles. In addition, the SP-5006 is equipped with seven sets of interfaces to attach over 40 different accessories, making customization options virtually unlimited.
