Vector Optics Sentinel‑X Pro 10‑40x50 SFP Riflescope – Extreme Precision for Benchrest and Long-Range Shooters
The Vector Optics Sentinel‑X Pro 10‑40x50 is a premium Second Focal Plane (SFP) riflescope purpose-built for precision shooting disciplines such as benchrest, field-target, and long-range competitions. With its impressive 10x to 40x magnification range, advanced optical design, and center-dot illuminated reticle, this scope is designed to meet the demands of expert marksmen seeking ultimate repeatability and clarity at long distances.
Unmatched Optical Performance with Fully Multi-Coated Lenses
Outfitted with a large 50 mm objective lens and fully multi-coated optics, the Sentinel-X Pro delivers outstanding brightness and sharpness throughout its entire zoom range. Even at 40x magnification, the image remains clear, making this scope ideal for daylight and indoor shooting environments where fine target definition is critical.
Purpose-Built COM‑25M Reticle for Target Precision
Designed for ultimate clarity and precision, the COM‑25M center dot reticle is tailored specifically for 25-meter benchrest shooting. The ultra-fine 1.5 mm illuminated center dot offers outstanding accuracy without cluttering the field of view. Because it's housed in the second focal plane, the reticle remains the same size at all magnification levels, ensuring a stable aiming reference.
