ZEISS Conquest 6.5-20x50 AO MC Riflescope w/Mil-Dot (#43) Reticle (5214519943)

Conquest riflescopes are Best-in-Class solution that is driven to acknowledge the requirements of the American hunter and shooter.

Zeiss riflescopes have excellent price performance ratio with Zeiss branded quality. Features are: fully multi-coated with Zeiss MC coatings, durable one piece tube body and anodized finish, self centered 2nd image plain reticles, wide fields of view, 1/4 MOA, wide adjustment ranges, complete waterproof, dustproof integrities.

The diameter of a scope's center tube (or main tube) impacts the overall strength and durability of the rifle scope. And it obviously determines the size of bases and rings required for mounting. But beyond that, the center tube diameter must be adequate to allow a sufficient range of windage and elevation adjustment. Conquest riflescopes have either a 30mm or a one-inch center tube, depending on the model.

As light strikes an air-to-glass surface, a small percentage of light is reflected away to become stray light. This effect is limited when these glass surfaces are treated with a microscopic layer of refractive material, such as magnesium fluoride.

To achieve multicoating, several such refractive layers are applied. When properly applied, coatings can dramatically enhance light transmission properties by delivering more of the available light to the shooter's eye. Zeiss' two proprietary coatings are called T* and MC anti-reflective coatings.

All Conquest riflescopes, whether fixed or variable power, have constant eye relief throughout their power range. And the 6.5-20x50 riflescope is not an exception with its 4" eye relief distance.

Eye relief distance describes the distance between your shooting eye and eyepiece lens. It's an important safety consideration. Because if the eye relief is too short, there's an increased risk of dangerous contact between you and your scope under recoil.

Eye relief is determined by the field-of-view, and by the focal lengths of the objective lens and eyepiece lens. Generally, the higher the magnification and the larger the field-of-view, the shorter the eye relief.
