The Sightron SII Blue Sky, like other Sightron optics, has been designed, tested, and retested by sportsmen for sportsmen. The SII Blue Sky features features twist up/down eyecups which gives it the versatility to accommodate both eyeglass wearers and non-eyeglass wearer to find the perfect eye relief. The pull out sunshade reduces glare an protects the objective lens. Fully-coated lenses employ coatings on both surfaces of our precision ground glass to provide the maximum optical quality and light transmission.
Like all Sightron optics, the SII Blue Sky is built using 100% sealed system ensuring a lifetime guarantee of great performance even under the most extreme weather conditions. Extra Low Dispersion Glass is a special glass added to optical systems to prevent chromatic aberration. The scope is nitrogen filled to provide a lifetime of use from fogging and internal water buildup.
Sightron is confident enough in the SII Blue Sky that it offers a Lifetime Warranty.
