The M-TACTICAL ratchets up riflescope performance through a profound mix of optical design, superior glass, innovative materials and a 100 years of Nikon optical ingenuity. The proprietary glass and multi-coating technology used in these optics prioritizes bright, high contrast sight pictures–and those views are complemented by purpose-driven reticles designed for long range. All long-range M-TACTICAL models feature side-focus parallax adjustments, while the full range of models feature directional indicators on turrets, 4x zoom range and utilize robust 30mm main body tubes drawn from aircraft-grade aluminum alloy. Turrets and zoom rings have knurling that is ergonomically designed for comfortable function with virtually any finger size. Each M-TACTICAL riflescope is finished with ultra-matte anodizing for extreme durability and reliability during a lifetime of real world performance.
