For starters, it built with an aircraft grade aluminum alloy 30mm main body tube. With an Illuminated X-MRAD reticle, the riflescope delivers 25 MIL internal adjustment travel for the X-MRAD reticle. The reticle is placed in the riflescope’s second focal plane, so all holdover corrections, ranging and other measurements using the indicated reticle subtensions should be done at 16x magnification. The specialized reticle and adjustment system in the BLACK X1000 is a glass-etched MIL tactical-style variant with illuminated option. Windage and elevation turret internal travel is enhanced for long-range dialing and crisp, click-stop movements operate with no backlash and are both precise and repeatable. The X-MRAD reticle presents the shooter with clean and visually simple, yet highly functional and advanced tools for estimating range, maintaining holdovers or dialing elevation come ups and compensating for wind. An advantage of using these tactical-style reticles is that it can be applied to virtually any shooting application regardless of caliber or ballistic performance, and can be further optimized for specific shooting situations utilizing Nikon’s Spot On Ballistic Match Technology.
