Specifications for Nikon Prostaff 7 5-20X50 SF Riflescope:

Features of Nikon Prostaff 7 5-20x50mm Second Focal Plane Riflescope:

• Massive Adjustment Range with a larger body tube that allows for much greater windage and elevation travel - an important attribute for extreme long-range shooting.
• Rugged, 30mm Main Body Tube.
• Engineered for minimum weight and maximum strength and durability, Nikon builds these scopes from aircraft grade aluminum alloy and utilizes larger internal lenses for wider field of view. Larger tubes allow for superior wall strength and durability.
• Compatible with Spot On Ballistic Match Technology to maximize your long-distance accuracy with virtually any cartridge.
• Hand turn Reticle Adjustments with Spring-Loaded Instant Zero-Reset Turrets. To simplify field adjustments, Nikon has integrated this feature into all Prostaff 7 riflescopes. Just sight in as usual, then lift the adjustment knob, rotate to your zero, and re-engage.
• Fully Multicoated Optical System maximizes light transmission for a bright, high-contrast sight picture.
• Prostaff 7 riflescopes can be customized with Nikon's Spot On custom dials to match bullet drop for virtually any factory or custom load - allowing crosshair-center aiming for various distances.
• Choice of Nikon's BDC Reticle, which allows hunters to hold dead-on at ranges exceeding those previously thought possible. The BDC's unique see-through ballistic circles offer an incredible advantage for long range shooting, yet allow a normal sight picture for shorter range shots where the crosshair itself is the aiming point.
• Smooth Zoom Control for quick magnification changes.
• Second Focal Plane.
• Nitrogen-purged and O-ring sealed.
• 4 inches of constant eye relief.
• 4x zoom technology.
• Precise, positive click 1/4-inch at 100 yds adjustments.
• Quick focus eyepiece.
