The Optika 6 5-30×56 riflescope sets a high standard in optical sighting devices for long-range sport and precision shooting. Equipped with 2 extra-low dispersion (ED) glass elements located in the objective lens, the 5-30×56 model provides maximum all-round image clarity and high resolution regardless of distance. The large 34 mm main tube diameter provides a wide range of windage and elevation adjustments, allowing the shooter to easily make these adjustments in changing terrain conditions. All 5-30×56 models are equipped with crosshairs in the first focal plane and a freely accessible, zero-stop windage and elevation adjustment mechanism, which is complemented by a parallax adjustment function that facilitates precise aiming when shooting at long distances. Optional reticle designs include a patented “tree” reticle with MIL scale, which allows for precise aiming throughout the entire magnification range as well as precise insertion and removal when used in the field.
