The Schmidt & Bender 2.5-10x56mm Klassik riflescope is a tried-and-true hunting optic that excels in situations with poor lighting conditions such as the break of dawn or the failing light of dusk. Its excellent low light performance can be attributed to its large 56mm objective lens and the use of premium SCHOTT glass to make the best use of the last remaining light – resulting in an image with the brightness and contrast akin to high-quality binoculars. The 2.5-10x56mm Klassik also comes standard with Schmidt & Bender exclusive features including high-precision adjustments, multilayered glass coatings, and solid anodized aluminum construction that ensures the Klassik riflescope meets and exceeds the needs of the 21st century hunter. The 2.5-10x56mm Klassik also features an illuminated reticle with an auto-off function, and can be upgraded with the advanced Klassik CT turrets.
