Steiner combines military-grade durability, German precision, and American craftsmanship with the H6Xi. Available in 2-12x42mm, 3-18x50mm, and 5-30x50mm configurations, the H6Xi comes standard with high-density HD glass with special multi-coatings. This gives the H6Xi a light transmission of 92% for optimal brightness, clarity, and definition even in the golden hours of dawn or dusk. The H6Xi’s optical abilities also extend to an extra wide field of view, allowing the user to acquire, track, and engage targets faster and easier even at higher magnifications. In addition to its impressive optical abilities, the H6Xi also features extreme ruggedness. The one-piece tube is milled from a solid piece of 6061-T6 aircraft grade aluminum, and a shockproof, waterproof, and fog proof design ensures a lifetime of reliable service. Other features of the H6Xi include a fine parallax adjustment down to 25 yards, and a locking diopter allows you to secure your preferred reticle focus to maintain optimal clarity.
