Special Features

• XD extra-low dispersion lens elements reduce chromatic aberration and color fringing across the full 5x zoom range, producing accurate color rendering and sharp resolution at maximum magnification.
• XR fully multi-coated lenses maximize light transmission at every glass surface, maintaining a bright, high-contrast image during low-light range sessions and early morning field use.
• ArmorTek exterior lens coating bonds to the outer glass at the molecular level, resisting scratches, oil, and debris through regular field and range handling.
• The RZR Zero Stop turret system lets you dial elevation corrections and return to your established zero with a single downward rotation, eliminating the need to count clicks back to zero under pressure.
• The Precision-Glide Erector System keeps the zoom mechanism moving smoothly and tracking accurately across the entire magnification range without binding or image shift.
• The EBR-4 reticle provides hash-marked holdover and windage correction lines in MOA increments, giving you fast, math-free hold references at any distance without leaving your shooting position.
• Backed by the Vortex VIP Unlimited Lifetime Warranty with no questions asked.
