The Vector Optics Sentinel 4-16x50 GenII is built for confident precision at medium to long distances, combining a brighter ED-glass system with dependable tracking and a strengthened mechanical platform that maintains accuracy shot after shot. The larger 50 mm objective combined with fully multi-coated optics ensures improved light transmission, reduced glare and sharp image definition across the entire magnification range. Constructed from high-strength 6063-T6 aluminum, the scope features fully multi-coated lenses that enhance contrast and maintain clear target visibility in demanding shooting environments. The reinforced 30 mm nitrogen-purged monotube provides structural rigidity and supports a wide internal adjustment range, offering precise 0.25 MOA click values ideal for medium- to long-range shooting and fine precision corrections. The etched SFP VSE‑4 MOA reticle maintains its visual proportions across the entire magnification range, ensuring a consistent sight picture while providing reliable holdovers, windage references, and a floating illuminated center dot for precise aiming. The elevation turret includes a mechanical zero-stop system for instant and repeatable return-to-zero, while the side-focus adjustment ranges from 9.144m (10 yards) to infinity, supporting both close-range sight-in work and extended-distance engagements. With a generous eye relief of 100 mm and a precision-focused optical design, the Sentinel 4-16x50 GenII is ideal for shooters demanding optical quality, mechanical reliability, and consistent field performance. Included accessories: High-profile Picatinny mounts, lens caps, cleaning cloth and a sunshade. Precision Targeting for Medium- to Long-Range Engagement Precision shooting disciplines require optics capable of delivering clarity, stability, and reliable mechanical performance under varying conditions. The Sentinel 4-16x50 GenII provides the magnification range, optical resolution, and mechanical consistency required for confident medium - and long-distance shots. VSE-4 MOA RETICLE DESIGN FEATURES The VSE-4 MOA reticle is designed for practical precision shooting, offering a clean and uncluttered layout with straightforward MOA markings for reliable elevation and windage reference. CLEAR FLOATING CENTER DOT The illuminated floating center dot provides a precise aiming reference, improving visibility in low-light conditions and supporting accurate shot placement at any magnification. SIMPLE AND EFFECTIVE MOA MARKINGS The reticle features evenly spaced MOA hash marks along the vertical and horizontal axes, allowing shooters to apply consistent holdovers and windage corrections without visual clutter.
