Sightron engineers sought to up the ante to create the perfect riflescope for hunting in a variety of lighting conditions when designing the Sightron S1 3.5-10x50mm G2 riflescope. Using modern optical designs and manufacturing techniques, the S1 3.5-10x50mm G2 sports a large 50mm objective and provides clear and sharp views in just about any lighting due to Sightron's all-glass lenses and exclusive MC-333 lens coatings. Sightron's Precision Focus Eyepiece provides a customizable sight picture with extended eye relief. A compact, lightweight 1-inch aircraft aluminum tube houses an all-new erector tube system which is nitrogen charged, O-ring sealed, providing IPX7 waterproof and fogproof performance, and construction is 1,000G rated shockproof. All of this provides the ability to take the hunt to the field earlier and later than ever and handle whatever obstacles Mother Nature throws at you.
